DESCRIPTION
BPA Contract 95622. This contract will result in the completion of one final design for the Brush Creek site, four 60% designs (two on Gate Creek, two on Grouse Creek) and five 30% designs (two on Twin Creek, three on Deep Creek) to correct fish passage barriers. Two barriers on Goose Creek that were originally part of this design contract were corrected in FY23 under contract # 90903. One barrier on Pole Creek that was originally part of this contract is expected to be corrected in FY25. The 13 fish passage barriers are on tributaries to the Lower Chiwawa River, and the correction of these barriers will improve connectivity to cold, clean, and complex habitat, while maintaining and improving ecosystem functionality vital to the persistence and recovery of ESA-listed species.

Work to complete designs for the 13 culverts was initiated in FY22 under
the agreement #88609. In FY22 initial data collection and planning began for
all 13 culverts. This work included site visits with our engineer, the Forest
Service, WDFW and other project stakeholders. We collected watershed data,
topographic information, and steam specific information for each site.
Hydrology and hydraulics modeling has been completed for each site.
