Expansion of Model Watershed Project in response to NPPC and ISRP evaluation to address a holistic approach for expanding the MWP boundaries from 3 watersheds to the entire upper Salmon Sub-basin. In response to ISRP's comments, site specific restoration plans give the guidance in restoring physical process for fish habitat restoration.
Expansion of Model Watershed boundaries.
This information was not provided on the original proposals, but was generated during the review process.
The increase in scope is because it's the Model Watershed boundaries have enlarged to include the Salmon Subbasin from headwaters to the mouth of the Middle Fork Salmon River. The increase in budget is due to the use of the most current technology, using aerial surveys with 2-ft contours, to achieve the objectives that were approved for FY 2000 (Section 3, Objective 2 for $370,000). This new work will significantly contribute to the subbasin assessment work being performed to support the subbasin planning efforts expected in the next several years.
This new work should be technically reviewed by CBFWA before funding.
