DESCRIPTION
BPA Contract 90940. This contract will result in the completion of four final designs (two on Gate Creek and two on Grouse Creek) and seven 30% designs (two on Twin Creek, three on Deep Creek, one on Pole Creek and one on Brush Creek) to correct fish passage barriers. Two barriers on Goose Creek will be corrected in FY23 and that work is described in CR-357366. 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. Additionally, 60% designs are completed, and final designs are in progress for both barriers on Goose Creek. 30% designs are expected to be completed for both sites on Gate Creek and both sites on Grouse Creek by the end of FY22.
