2 Fish screens in Columbia River Basin

3 Southeast Idaho Fish screening involvement Trout Unlimited Henry s Fork Foundation Friends of the Teton River Idaho Dept. Fish & Game Caribou-Targhee NF U. S. Fish and Wildlife Service Hydroelectric companies Henrys Fork South Fork Blackfoot Portneuf Bear

4 Cutthroat trout and life histories Resident MT ID WY Fluvial UT Adfluvial

5 SE Idaho tributaries focus TU conservation model

6 Southeast Idaho Fish Screens No ESA listed fishes..no required fish screen criteria. Generally start with NOAA Fisheries screen criteria..but, may not end up staying there depending on given situation (e.g., retrofit or funding limitations)

7 Fish screening process Partitioning of the screening process: 1) Planning & design, fabrication, construction, funding, etc. and 2) operation and maintenance

8 Southeast Idaho Inland Fish Screen Inventory and Database Objectives: Compile fish screening information into a single database Provide a common repository for sharing fish screening experience to facilitate future screening efforts Review of what s working, and not, and plan and prioritize modifications (at least among TU coordinated screens) Provide outreach and education about fish screens to water users, landowners, anglers, etc.

9 SEIIFSID Database Water rights Diversion/ Fish screen Fish screen Costs Funding location general types M to M 1 to M 1 to 1 1 to M M to M Started by requesting existing databases NPCC, IDFG, ODFW WDFW, MFWP A comprehensive repository of information Contacted organizations that have coordinated screens in project area

10 SEIIFSID Inventory Collect information that may not be readily available in files Develop survey protocol and form Contemporary information About 20 screens inventoried in field to date Diversion Fish screen general Fish screen types Drum Vertical Horizontal Cone Pipe

21 Southeast Idaho Fish Screens Next steps: Continue with database development Inventory remaining screens Develop a rating system for screen function to assist with ranking needs for modifications Compile other information in the winter Survey a subset of screen next year to evaluate performance?
