Project history
Since June 1993, WDFW has performed preventative maintenance and major repairs on the majority of completed Phase 2 fish screen facilities. Currently, WDFW is responsible for 11 sites (FY 96). Remaining sites are Bureau of Reclamation (BR) responsibility. Duties also include acting as BPA's local liaison with the diversion owner. WDFW monitors and verifies diversion owner performed "routine" maintenance subject to reimbursement by BPA and processes claims for payment.

Biological results achieved
Biological evaluation of recently completed Phase 2 fish screens by Battelle (Proj # 8506200) has shown juvenile salmonid survival and guidance rates approaching 100%. Without comprehensive
preventative maintenance, long-term screen performance will decline as will fish survival. The life span of BPA's investment in new screens also depends on a program of regular maintenance.

Annual reports and technical papers
Yakima Basin BPA Phase II Fish Screen O&M, Progress Reports 1 - 5 (#1: 5/93 - 8/93; #2: 9/93 - 12/93; #3: 1/94 - 5/94; #4: 6/94 - 12/94; #5: 1/95 - 6/95)

Management implications
Not Applicable.

Specific measureable objectives
Perform operation and preventative maintenance on assigned Phase 2 fish screen facilities in order to preserve facility life span and maintain peak fish protection and guidance efficiency on a long-term basis.

Testable hypothesis
Not Applicable.

Underlying assumptions or critical constraints
Optimal long-term juvenile fish protection assumes the design and initial construction provide the best possible fish protection and bypass guidance at the beginning of operation. Given proper design and construction, long-term protection effectiveness is dependent on preserving design specifications through consistent and thorough O&M.

Methods
Not Applicable.

Brief schedule of activities
FY 97: Continue O&M of 11 assigned Phase 2 screen facilities. New assigned sites coming online include Fogarty, Bull, Ellensburg Mill, Clark and Lindsey bringing the total to 16 sites.

Biological need
Juvenile anadromous salmonid survival is being increased at Yakima Basin irrigation diversions by constructing state-of-the-art fish screen facilities (Proj # 9105700 and # 9107500). However, the improvements in survival and capital facility investments can only be sustained by a commitment to comprehensive and regular O&M. Failure to do so will result in facility deterioration and an increase in fry, fingerling and smolt injury and mortality.

Critical uncertainties
None

Summary of expected outcome
High initial survival and guidance of juvenile fish at Phase 2 screens can be sustained in the long-
term by implementing regular preventative maintenance.

Dependencies/opportunities for cooperation
The addition of new sites each fiscal year is dependent on completion of fabrication (# 9105700) and civil works construction (# 9107500). WDFW derives the O&M budget based on assumed "online" dates, but delays can result in lower expenditures and carrying over funds to the next fiscal year. WDFW and BR work cooperatively to assure that project objectives are attained with the least cost to BPA.

Risks
None

Monitoring activity
Monitoring and evaluation of Phase 2 fish screen performance is accomplished by Pacific Northwest Labs (Battelle) under contract with BPA (Proj. # 8506200).
