| Develop Alternative Water Source | 4.13 PNNL,USGS: Evaluate increased production potential of chum salmon using artificial hyporheic upwelling | Task 4.13 Develop alternative water source - Evaluate increased production potential of chum salmon using artificial hyporheic upwelling. Description: PNNL and the USGS will collaboratively select suitable sites for experimentally creating areas of hyporheic upwelling for spawning chum salmon. USGS and PNNL will map the physical habitat (e.g., depth, velocity, substrate, embeddedness) and hyporheic conditions (bed temperatures, river surface temperatures, bank seepage) around known potential chum salmon spawning locations (e.g., Multnomah site). This information will be used in the USGS spawning habitat model to predict the suitability of the mapped areas for chum salmon. Potential areas selected for hyporheic manipulation will be those judged suitable for chum salmon spawning based on suitable depths, velocities, and substrates with the exception of the presence of warmer hyporheic bed temperatures, which are characteristic of heavily used sites. In other words, nonuse sites will be chosen that appear identical to sites used for chum salmon spawning, but will not have the thermal cues that chum salmon require for selecting redd sites. Agency conducting work: PNNL and USGS Start and end dates: 10/1/06-1/1/07, 10/1/07-1/1/08, 10/1/08-1/1/09. Deliverables: During FY2007 PNNL will assist the USGS with habitat model modification and validation. During FY2008 the model will be used to identify potential locations where artificial upwelling could be field tested. During FY2009 a pilot scale test would be conducted at the selected location to determine whether spawning could be induced in an appropriate location. Results of the experiment would be summarized in an annual report during FY2009. | 10/1/2006 | 9/30/2009 | $80,232 |

| Analyze/Interpret Data | 4.1.2 USFWS: Model, validate and calibrate one-dimensional steady and unsteady flow hydraulics for the lower study site using a One-Dimensional water surface model such as the USACE’s River Analysis System (HEC-RAS) or MASS1. | Subtask 4.1.2: Analyze/Interpret Data – Model, validate and calibrate one-dimensional steady and unsteady flow hydraulics for the lower study site using a One-Dimensional water surface model such as the USACE’s River Analysis System (HEC-RAS) or MASS1. Description: Instead of developing an expensive and complicated finite element hydrodynamic model capable of modeling velocities with two vector components, we have elected to build a simpler, cost effective and appropriate one-dimensional model. Specifically, we will construct the model, validate and calibrate the output and produce water surface profiles. These 3-dimensional water surface elevation profiles (grids) will be produced for a range of Bonneville discharges, tides and backwaters relevant to the chum spawning season (November and December). We will use the long term tidal Gage at the Interstate 5 Bridge (RM 105) for the downstream terminus and control for both steady and unsteady flow simulations and the Bonneville tailwater gage located at river mile 145 for the upstream terminus and control. We would normally not propose building two separate models but each has some advantages over the other and actually supports the other through cross validation of the other. Agency Conducting Work: USFWS Start and end dates: 10/01/2006 through 9/30/2007 – Conduct actual one-dimensional modeling – 10/01/2007 through 9/30/2008- Validate/Calibration and produce grids – 10/01/2008 through 9/30/2009 – Provide for internet access to all simulations. Deliverables: We will produce a matrix of GIS grids for a range of potential Bonneville Dam discharges and downstream backwaters sufficient for the November and December spawning period. For each modeled water surface elevation we also produce a respected depth grid. | 10/1/2006 | 9/30/2009 | $37,500 |

| Analyze/Interpret Data | 4.1.3 USFWS: Update the existing hydrodynamic model bathymetry and conduct refined simulations of water surface elevation, depth and velocity throughout the Ives Island site. | Subtask 4.1.3: Analyze/Interpret Data – Update the existing hydrodynamic model bathymetry and conduct refined simulations of water surface elevation, depth and velocity throughout the Ives Island site. Description: Using the same hydrodynamic model previously implemented by (Garland et al. 2003) we will incorporate the refined bathymetric data into the model and rerun the model at a finer resolution than our previous simulations. The previous simulations were only made at 10 kcfs increments and used a less resolute bathymetric model. We will conduct revised simulations for a wide range of potential hydraulic conditions likely to occur during spawning season. For each simulation we will include a wide range of Hamilton Creek discharges, tidal stages and Columbia River backwater events (i.e. high Willamette River stage). These simulations will provide the relevant data regarding water surface elevations, depths and velocities required to account for and protect chum salmon redds from dewatering which can not be conducted. This data will also be used in objective 2.0 to refine and incorporate the suitability criteria collected in 2003 – 2005 into our suitability and habitat models which will provide for more approximate estimates of habitat and redd capacity. Agency Conducting Work: USFWS Start and end dates: 3/01/2007 through 9/30/2007 Deliverables: For each refined hydrodynamic simulation we will produce three dimensional GIS surfaces of water surface elevations, depths, velocities and shoreline coverage’s. These layers will be produced for each simulation in the form of triangulated irregular network (TIN), raster grid or vector layer in our GIS. | 3/1/2007 | 9/30/2007 | $30,000 |

| Analyze/Interpret Data | 4.11 PNNL: Assess hyporheic water temperatures and flow in chum spawning areas. | Task 4.11 Analyze/Interpret Data-Assess hyporheic water temperatures and flow in chum salmon spawning areas. Description: During FY2007-2009, hyporheic temperature and water level data will be used to evaluate how tailwater elevation fluctuations affect temperature gradients and water flow (i.e., upwelling) in chum salmon spawning areas during spawning, incubation and emergence (mid November to end of June). A major incentive for this work is to determine whether there are operational thresholds that can be modified to improve the quantity of spawning habitat or the quality of the incubation environment during the incubation period. Past analysis efforts have been focused near the Ives north channel near the mouth of Hamilton Creek. During FY2007-FY2009, we will expand analysis efforts to include newly discovered chum salmon spawning areas near Multnomah Falls and I-205. Agency conducting work: PNNL Start and end dates: 10/1/06-6/1/07, 10/1/07-6/1/08, 10/1/08-6/1/09. Deliverables: During FY2007-FY2009 we will complete an analysis of the relationship between tailwater elevation, Bonneville Dam discharge, and resulting changes in hyporheic temperature and the magnitude and direction of hyporheic flow. The analysis will be presented in an annual report, and will build on past efforts, which identified areas of warm upwelling water preferentially selected by chum salmon for spawning. Results will evaluate how operational changes affect the distribution and characteristics of previously identified areas, and will provide index data that can be used to compare to newly identified chum salmon spawning locations. | 10/1/2006 | 7/1/2009 | $78,892 |

The resultant equation will be verified with empirical use data (redds) and then be balanced for errors of omission and commission. Agency Conducting Work: USFWS Start and end dates: 4/01/2007 through 4/01/2008 Deliverables: A multivariate regression (s) will be developed using the SAS statistical software and the resultant equation will be used in our GIS with the individual habitat metrics to quantify habitat. | 4/1/2007 | 4/1/2008 | $30,000 |

Methods: We will calculate the mean number of digs, tailcrosses, chases, and tailbeats made per 15-min interval both before (base flows) and during reverse load following events. We will use 2-sample t-test to compare each metric for each pair. We will then pool data for season and conduct a global comparison for these metrics for the season. We anticipate declines in the frequencies of the metrics as flows increase. Form each DIDSON file, we will also determine if and when chum salmon are forced from their redds by high flows, what those flow levels are, and the duration fish are gone before they return. Fishery managers need this information to better shape flows from Bonneville Dam during high flow events. Agency Conducting Work: USGS Start and end dates: 10/01/2006 through 2/28/2009, Deliverables: Identification of flows during reverse load following that significantly alter chum salmon spawning behavior and force them to abandon redds. | 10/1/2006 | 9/30/2009 | $37,427 |

| Analyze/Interpret Data | 4.3.2 USGS: Quantify chum redd superimposition near Ives Island in relation to available habitat and fish abundance | Subtask 4.3.2: Analyze/Interpret Data - Quantify the extent of chum salmon redd superimposition in the Ives Island area in relation to habitat availability and fish abundance Methods: The locations of all redds will be incorporated in a GIS to create a map of all undisturbed redds and superimposed redds. These locations will be overlayed on a map of suitable spawning habitat predicted using the chum spawning habitat model previously developed by this project. Our logistic regression model of spawning habitat predicts the suitability (on a scale of 0 to 1, with 1 being most suitable) of the habitat broken into 2x2 m cells. We will construct a frequency distribution of the number of all redds in each suitability class (i.e., 0-0.1, 0.1-0.2, etc.) and compare it to a uniform distribution (assuming redds were spread evenly over available suitable habitat) using the Kolomogorov-Smirnov test (alpha=0.05). We will then conduct a similar test for superimposed redds alone to determine if superimposition is occurring in specific areas. The spatial area of all redds constructed in a given year will be summed and compared to the available suitable (probability >0.5) habitat area predicted by our spawning model to determine how many redds can be constructed at Ives Island without redd superimposition (i.e., redd capacity). If superimposition occurs when redd capacity has been exceeded, we will conclude that superimposition is a response to habitat availability. If superimposition occurs when redd capacity has not been exceeded, then we will conclude that habitat availability is not a factor in redd superimposition. If this is true, we will implement WE X to further validate this conclusion. The percentage of redds superimposed will be related to fish abundance in the Ives, and other, spawning areas by regressing percent redd superimposition against annual fish abundance to determine if a relationship exits. Our expectation is that as fish abundance increases, redd superimposition will increase as well as competition for spawning space intensifies. Finally, for superimposed redds, we will calculate the mean area superimposed and identify the location in the initial redd that is most commonly re-excavated Agency Conducting Work: USGS Start and end dates: 12/01/2006 through 2/30/2009 Deliverables: GIS layers showing the localized areas within the larger spawning area where superimposition occurs. Understanding of whether redds are constructed in proportion to habitat suitability and availability. Estimate of chum redd capacity.

Redd locations from the exclusion test will overlaid in GIS on the historical locations to determine the percentage of redds constructed at historical redd locations and at locations not used historically. Using our existing spawning habitat model, determine the suitability of the redd locations used when fish are prevented from superimposing redds. We will construct a frequency distribution of the habitat suitability classes used in the exclusion tests and from historical redd locations. We will compare the two distributions using the Kolomogorov-Smirnov test to determine if excluded fish use habitats of equal, lesser, or higher suitability.

Description: By incorporating precisely georeferenced still images (+/- 3 cm) from the video into our GIS we can conduct a number of spatial and temporal analyses that would otherwise be impossible. In the GIS each redd, redd pocket and total disturbed redd area will be digitized with a polygon and assigned an identification number. Polygons will be subsequently populated with a suite of attributes including: temporal (start/end time, time to completion, time to first superimposition, hen residence time) and physical: size, distance to nearest redd, area between adjacent redds, % overlap-disturbed area, % overlap egg pockets and number of egg pocket superimposed. The analysis of these attributes within a spatiotemporal framework is essential to understanding the mechanisms of redd superimposition Agency Conducting Work: USFWS Start and end dates: 1 month annually 10/01/2006 through 2/28/2009 Deliverables: We will provide a table outlining the spatiotemporal mechanisms of redd superimposition. This will include the number of redds per unit area that precludes superimposition, the density at which redd margins overlap and the point at which superimposition of actual egg pockets will occur.

| Analyze/Interpret Data | 4.3.8 USGS: Evaluate effectiveness of increased flows at reducing redd superimposition | Subtask 4.3.8: RM&E and Data Management - Evaluate effectiveness of increased flows at reducing redd. Methods: We will compare the rates of redd construction and redd superimposition in the main Ives Island spawning channel before and after tailwaters are increased to 13.5 ft to determine if the number of new redds and superimposed redds decreases under the higher flow. Summarize the number of redds constructed in the north Ives Island spawning channel and any other newly inundated areas and the extent of redd superimposition to determine if fish did use new habitat. We will accept the hypothesis that increasing tailwater elevation reduces redd superimposition in the Ives spawning channel if no new superimposition is observed after tailwater is increased. If superimposition is observed in the main Ives spawning channel after tailwater is increased, then we will calculate the mean spatial extent of redds superimposed at the 13.5 ft tailwater elevation and compare it to that of the 11.5 ft tailwater to determine if redd-specific pattern of superimposition is related to tailwater elevation. Agency Conducting Work: USGS Start and end dates: 12/01/2006 through 2/30/2009, dependant upon the 13.5 operation occurring.

| Collect/Generate/Validate Field and Lab Data | 1.10 PNNL: Locate and map chum salmon deepwater spawning areas | Task 1.10 Collect/Generate/Validate Field and Lab Data - Locate and map chum salmon deepwater spawning areas. Description: We will conduct a survey using a boat deployed underwater video camera system to document deepwater spawning of chum salmon within Hamilton Slough and at the mouth of Woodward Creek near the Ives and Pierce Island complex. We propose additional searches near the I-205 bridge site and the Multnomah Creek areas to determine if chum salmon area spawning in deeper water adjacent to these sites. Surveys conducted in 2005 have documented chum salmon redds in 3.6 m water depth at the Rivershore chum salmon spawning site (near the I-205 bridge). For deepwater surveys, line transects will be established at regular intervals (20 m) and visual images of redds and bottom substrate will be recorded using an underwater video recording system. One deepwater survey will be conducted immediately after the peak-spawning interval (i.e., mid-November to early-December). All redds found will be geo-referenced using a real-time GPS system marked with a GPS; relative precision of positional data will be based on fixed geo-referenced points obtained at a suitable GPS base station and relative precision of positional data is expected to be ~ 0.25 m. Depth of the camera relative to the substrate, the number of transects, and distance covered during each transect will be recorded to estimate the amount of bottom area covered during each survey. This will allow us to estimate redd densities if the entire survey area cannot be effectively surveyed with the video system. All redds, and survey locations will be geo-referenced using GPS and subsequent map layers will be created using GIS. Additional data which can be collected at the time of initial surveys includes grain size and bed velocities at redd sites. Agency conducting work: PNNL Start and end dates: 11/1/06-12/15/06, 11/1/07-12/15/07, 11/1/08-12/15/08. Deliverables: One survey will be conducted during peak spawning (flows permitting during late November to early December) to search for chum salmon redds constructed adjacent to and downstream from the North side of Ives Island. Additional surveys will be conducted to document chum salmon redds constructed in water depths greater than 1.2 m near I-205 bridge, and Multnomah Creek chum salmon spawning locations. During the survey, we will sample arbitrary transects established perpendicular to flow at 25m intervals, and map redd locations using a gps.

| Collect/Generate/Validate Field and Lab Data | 1.11 PNNL: Locate and map fall Chinook salmon deepwater spawning areas | Task 1.11 Collect/Generate/Validate Field and Lab Data - Locate and map fall Chinook salmon deepwater spawning areas. Description: We will conduct surveys using a boat deployed underwater video camera system to document deepwater spawning of fall Chinook salmon within several search zones near the Ives and Pierce Island complex. Past surveys conducted by PNNL have documented that the majority of the fall Chinook redds occur adjacent to the main river channel side of Pierce Island. Figure 4.4.4 describes the general search zones for both fall Chinook and Chum salmon. Surveys conducted in the fall of 2003 have documented as many as 330 redds in water depths exceeding 1 m. Surveys in the fall of 2005 have documented a small number of fall Chinook salmon redds (~10) downstream of Moffett Creek near the main river channel in water depths > 7.6 m. Based on this new finding expanded searches are proposed at additional areas that are characterized as having suitable habitat. These additional surveys will further improve population estimates for fall Chinook salmon spawning below Bonneville Dam, We will attempt to determine the relationship between spawning populations using shallow water habitat and spawning populations using deep-water habitat to determine if population estimates from shallow water surveys can be used as an index for the total population. We will work with the USFWS and USGS personnel to use new technologies (acoustic camera and high definition eco-sounders) to further identify and enumerate redds occurring in deepwater areas adjacent to Pierce Island and other areas (Moffett Creek). For deep water surveys, line transects will be established at regular intervals (20 m) and visual images of redds and bottom substrate will be recorded using an underwater video recording system. A minimum of two deepwater surveys will be conducted immediately after the peak-spawning interval (i.e., mid-November to early-December) to document fall Chinook salmon spawning. All found redds will be geo-referenced using a real-time GPS system marked with a GPS; relative precision of positional data will be based on fixed geo-referenced points obtained at a suitable GPS base station and relative precision of positional data is expected to be ~ 0.25 m. Depth of the camera relative to the substrate, the number of transects, and distance covered during each transect will be recorded to estimate the amount of bottom area covered during each survey. This will allow us to estimate redd densities if the entire survey area cannot be effectively surveyed with the video system. All redds, reference targets, and survey locations will be geo-referenced using GPS and map layers will be created using a GIS. Additional data which can be collected at the time of initial surveys includes grain size and bed velocities at redd sites. Figure 4.4.4.

Chinook redds constructed in water depths greater than 1.2 m. but less than 9 m will be mapped using a GPS. Additional habitat parameters such and substrate composition and bed water velocities will also be collected at selected sites. An expanded fall Chinook salmon population estimate will be estimated based on redds found and video coverage area. ..

| Collect/Generate/Validate Field and Lab Data | 4.10 PNNL: Map bed temperatures in chum salmon spawning locations over a range of river discharges | Task 4.10 Collect/Generate/Validate Field and Lab Data - Map bed temperatures in chum salmon spawning locations over a range of river discharges Description: Spawning habitat modeling was previously completed using habitat metrics such as depth, velocity, and substrate as part of BPA project 199900301 for the Ives Island study area (Tiffan et al., 2003). Since creation of the model, additional habitat metrics such as hyporheic temperature have been discovered to be important indicators of preferred chum salmon spawning location in the Ives Island Area (Geist et al., 2002). Preliminary, unpublished data collected during 2005 in the Multnomah Falls and I-205 chum salmon spawning locations suggest chum salmon are also using warm, upwelling hyporheic water as a spawning cue in those locations. Past work to monitor hyporheic temperatures over time in the Ives Island Area have also shown that hyporheic temperature profiles vary with changing river discharge. During FY2007-FY2009, we will map hyporheic temperatures in chum salmon spawning areas within the Ives Island, Multnomah Falls, and I-205 sites to determine how hyporheic temperature profiles vary with changes in river discharge. Temperature data will be collected from a depth 10 cm below the riverbed and mapped using a GPS (Geist et al., 2002). We will collaborate with the USGS and together collect traditional spawning habitat data (e.g., depth, velocity, and substrate) at locations where we conduct temperature mapping. We will attempt to measure temperature profile differences within a spawning season and also between multiple years by mapping hyporheic temperatures at two different river discharges each spawning season FY2007-FY2009. The data will be incorporated into the existing USGS/USFWS habitat suitability model as they become available.

Deliverables: At the end of each spawning season, we will provide the USGS/USFWS with GIS layers that include GPS coordinates of each temperature point, temperature data, and time of data collection so results can be correlated with river discharge and incorporated into the habitat suitability model. | 10/1/2006 | 9/30/2009 | $78,892 |

| Collect/Generate/Validate Field and Lab Data | 4.3.1 USGS: Map the extent of chum salmon redd superimposition in the Ives Island area | Task 4.3 Increase the spawning success of mainstem spawning chum salmon by reducing redd superimposition. Subtask 4.3.1: Collect/Generate/Validate Field and Lab Data - Map the extent of chum salmon redd superimposition in the Ives Island area Methods: We will locate redds being constructed by chum salmon by using an observation tower, shore-based, or snorkel observations as required. The main chum salmon spawning area at Ives Island is located below the mouth of Hamilton Creek and is typically less than 1 m deep and spawning fish can be readily observed. We will identify chum salmon redds by the presence of chum salmon on the redd. Each redd will be visited daily to determine when the redd is complete. A redd will be considered complete when no active digging is observed. In addition, use information obtained in Task 3.2 to confirm when a redd is complete. Once a redd is complete, 1” white, or light-colored, gravel will be placed over the entire surface of the redd so that the darker-colored, excavated substrate is just covered. This will enable us to document subsequent superimposition of the redd because the excavation by later-spawning fish will reveal the darker substrate underneath. The location, perimeter, and dimensions of each redd will be measured using a survey-grade GPS. Each finished and “covered” redd will be visited daily to determine its use by subsequent spawning chum salmon. We will record the location, start time, and end time that a previously-constructed redd is used by a subsequent spawner. When a subsequent spawning pair has completed spawning in a previously-used redd, we will map the area of the new redd as described above. In addition, we will measure the percent of the original redd’s area excavated and superimposed by the subsequent spawner by mapping the spatial extent of the original redd that is still covered by light gravel. When the measuring and mapping of both redds are complete, any excavated, darker substrate of the new redd will be covered with light-colored gravel. Redd superimposition will be quantified in other lower Columbia spawning areas if results at Ives Island suggest that superimposition rates are high and therefore is likely occurring at other areas.

| Collect/Generate/Validate Field and Lab Data | 4.3.3 USGS: Test the efficacy of reducing redd superimposition through exclusion tests | Subtask 4.3.3: Collect/Generate/Validate Field and Lab Data - Test the efficacy of reducing redd superimposition through exclusion tests Methods: If we determine that chum salmon redd superimposition occurs in the presence of available suitable habitat, we will determine if we can increase use of that habitat and thereby reduce redd superimposition by excluding fish from using previously constructed redds. We hypothesize that if fish are prevented from superimposing existing redds, they will spawn in unoccupied suitable habitat within the area. If so, we can conclude the redd superimposition is a behavioral choice rather than due to habitat availability. Areas of high redd superimposition will be identified at Ives Island or other spawning sites. After each new chum redd is constructed, we will cover the redd with wire mesh (e.g., chain-link fencing) and secure it to the riverbed with rebar staples. This will prevent subsequent fish from spawning in that redd. We will cover and record the location of all new redds. Redd locations will be plotted in a GIS.

Description: Using overhead remote video arrays we will record the progression of spawning, redd construction and the subtle behaviors involved from the first to the last redd in one or more documented superimposition sites. Each array will be fitted with a remote video camera with infra-red lights for night work and will digitally record georeferenced redd reconstruction data for a plot of approximately 300 m2 (Figure 1). Surveyed pins viewable within each video array will make it possible to register all pixels within the array with real-world coordinates for assimilation into our GIS. As spawning season progresses we will continue to record and incorporate these data into our GIS data base. One possible outcome is that redds margins overlap but that egg pockets are not actually excavated except during the highest escapements. Also some amount of superimposition could be natural and other more severe levels could be the result of limited spawning habitat. To further document this will we install D-ring fyke nets to catch excavated eggs as a qualitative measure of superimposition.

| Collect/Generate/Validate Field and Lab Data | 4.3.7 USGS: Reduce chum redd superimposition through flow management | Subtask 4.3.7: Collect/Generate/Validate Field and Lab Data - Work Element: Reduce chum redd superimposition through flow management. Methods: We will test the hypothesis that increasing river flows will reduce chum salmon redd superimposition in the main Ives spawning channel. Fishery managers are clearly interested in this and proposed trying this during 2005 by increasing Bonneville tailwater elevation to 13.5 ft (System Operation Request #2005-21; available at http://www.fpc.org/documents/sors/sor_currentyear/2005-21.pdf), but the SOR was never implemented. If fishery managers implement the 13.5 ft SOR, we will measure chum salmon spawning activity in the Ives Island spawning channel as described in above. In addition, we will use a DIDSON acoustic camera to survey this area for fish presence and redd construction activity under the 13.5 ft tailwater elevation. We have used the DIDSON on this project to successfully observe spawning behavior of chum salmon (Tiffan et al. 2005). We will continue to cover completed redds to document redd superimposition as previously described. We expect that at a tailwater elevation of 13.5 ft, velocities will be too high (>1 m/s) for chum salmon to construct new redds. Indeed this is the intent of the 13.5 ft SOR, which will theoretically protect previously constructed redds by creating habitat conditions that are unsuitable for later-spawning fish. We expect at 13.5 ft that later-arriving chum salmon will access newly available spawning habitat on the north side of Ives Island, where spawning was observed in 1998 and 1999 under higher flows. We will survey the channel on the north side of Ives Island for chum salmon presence, digging activity, spawning, and the number of redds and their locations when the tailwater is at 13.5 ft. Continue regularly scheduled monitoring of the number of fish using Hamilton Creek, Hamilton Springs, and Hardy Creek to determine if use of those areas increases in response to increased Columbia River flows. If the 13.5 ft SOR is not implemented due to uncertain water availability, then request 13.5 ft tailwater increase for a period of seven days to test the stated hypothesis and monitor fish response as described above. The obvious risk associated with this short-term test is that some redds might be dewatered if fish indeed spawn in new habitats at higher riverbed elevations. Because the spawning area on the north side of Ives Island where fish have been observed spawning in 1998 and 1999 would be covered by pools after water recedes, this might afford some protection for eggs deposited in that area. The risk does remain however, but it should be weighed against the loss of eggs through superimposition if superimposition is not mitigated in years when it is known to occur.

Methods: During periods of extreme reverse load following at Bonneville Dam (i.e. flows >200kcfs), we will evaluate the effects on chum salmon spawning behavior in the main Ives Island spawning area. Since reverse load following occurs at night, we will select an actively spawning pair and set a DIDSON acoustic camera to observe their behavior for a period of 4 h prior to an anticipated high flow event and then for the duration of the load following event. We will collect the following information from DIDSON images: digging frequency, frequency of tail crossing by the courting male, chasing events, and tailbeats/min as indication of swimming speed.

Subtask 4.5.1: Collect/Generate/Validate Field and Lab Data - Conduct fall Chinook diel spawning habitat use Surveys below John Day Dam with hydrophones. Description: We will conduct diel habitat use surveys in the tailrace of John Day Dams to determine the temporal distribution of fall chinook spawning. Diel surveys will be performed in addition to deepwater redd surveys. The primary goal of this objective is to maximize both the quantity and quality of tailrace spawning habitat by determining if existing dam practices negatively impact or limit spawning. To assess this, passive monitoring of spawning fall chinook activity will be recorded with hydrophones on a 24 h and seasonal time step. Underwater hydrophones will be deployed in one or more known spawning locations to document the temporal distribution of spawning behavior. Specifically, the unique acoustic signatures from redd construction via colliding substrate particles will be recorded as digs per unit of time. Auditory data will be verified with the use of an underwater video camera for diurnal events and a DIDSON acoustic camera will be used for nocturnal events.

The suspected spawning sites are shallower than those used by adjacent spawning fall Chinook and are comprised of smaller substrates. If steelhead are spawning there, they are listed under ESA. On two occasions, sportsman commented on the “ruffed up tails” of hen steelhead caught in the area and actually commented that these fish were “spawning” there. These interviews we conducted at the Rufus, OR boat ramp during our early December fall Chinook redd surveys and the accounts we to have occurred in February of 2002 and March of 2003. Additionally, steelhead have been documented spawning in the Hanford Reach of the Columbia River and historically spawned in the mainstem Columbia River. We will employ previously developed methods and identify any spawning steelhead and their redds in the John Day tailrace. Methods will include hydrophones to “listen” to potentially spawning fish and underwater video to confirm and map redds. Agency Conducting Work: USFWS Start and end dates: 02/15/2007 through 4/15/20078 and 02/15/2008 through 4/15/2008 and 02/15/2009 through 4/15/2009 Deliverables: We will listen for the distinct and unique sound signatures of steelhead constructing redds in real-time for the previously specified location. If spawning is identified we will record the signature as wav files and then locate and confirm visually or with underwater video cameras the presence steelhead and redds in the area. Images from the DIDSON and scientific echosounder will also be archived. Locations will be mapped with GPS for later dissemination and publication. | 2/15/2007 | 4/15/2009 | $12,000 |

Subtask 4.7.1: Collect/Generate/Validate Field and Lab Data – Conduct mainstem Columbia River tule fall Chinook redd surveys in the below Bonneville Dam in the Ives Island area. Description: In past years staff biologist have observed ESA listed tule fall Chinook (Chinook Lower Columbia River ESU) spawning in shallow water with the Ives Island complex. This spawning was observed in late September and was documented over several years. WDFW also conducted some exploratory seining and collected newly emergent Chinook salmon in February. Based on temperature unit calculations those fish were likely spawned in September which is when tule fall Chinook spawn and shallow water spawning was observed. We will employ previously developed methods to identify any spawning tule fall Chinook or redds in mainstem Columbia River in water to deep to be observed from the surface. Methods will include hydrophones to “listen” to potentially spawning fish, underwater video to confirm the presence of tule redds.

Description: Feasibility study to enumerate juvenile chum salmon production from the mainstem Columbia River in the Ives/Pierce island area. The fish will be captured, marked, released, and recaptured within different periods, during which capture efficiency may be changing due to flow conditions. Consequently, it can be considered a stratified mark-recapture experiment. Each trap efficiency trial will be uniquely paired with one capture period (stratum). This can be accomplished by releasing marked smolts at relatively short intervals (e.g. a few days) so that there is little chance that fish will be recaptured in later strata. Agency conducting work: PSMFC. Start and End Dates: 01/15/2007 to 05/31/2009 Deliverables: Estimates of Ives/Pierce Island chum salmon production can be made by using traps in two different locations. The trap (probably a screw trap) would be placed in Hamilton Creek, and would be used to capture and mark fry leaving the stream. Estimates of trap efficiency and population size leaving Hamilton Creek could be made by re-releasing marked fish above the trap. The second trap would be in the mainstem Columbia below the mouth of Hamilton Creek, and maybe a fyke net or screw trap. Both unmarked and marked fry would be captured in the Columbia trap. The ratio of marked and unmarked fish captured will depend on the number of fry outmigrating from the Ives/Pierce Island complex relative to the number of fish migrating from Hamilton Creek. This ratio will allow estimation of the fry population originating from the Columbia River. The precision of the Ives/Pierce abundance estimate will depend on the relative sizes of the two populations and the absolute number of fish. | 1/15/2007 | 5/31/2009 | $104,125 |

ISRP PRELIMINARY REVIEW (Jun 2, 2006)
Recommendation: Fundable
NPCC comments: This is an extremely well-prepared and well-documented proposal. The background on technical and scientific issues is thoroughly presented. The project history appears complete and identifies that management calls upon the project for information to support hydrosystem operations, and that system operation modifications are under consideration because of the products of the project. There is a clear statement of objectives with a well-established need. The rationale and significance are clearly identified. Information on chum and fall chinook spawning and adaptation to the hydrosystem is crucial to system modifications to accommodate fish. The data will undoubtedly lead to management that will provide persisting benefits. The project is directed by experienced personnel who have an appropriate mix of expertise. The methods employed are sound, usual practices in fisheries investigations with the exception of the DIDSON sonar, which is rather new. The correct population parameters are being measured. The proposed activities are well integrated with past work and other agency projects.
