The North Yakima Conservation District proposes to create groundwater fed side-channel habitat in existing remnant and paleo-channels in the Naches River floodplain. Additional off-stream habitat in this reach of the Naches River will improve habitat conditions for Mid-Columbia steelhead, spring Chinook, coho, and bull trout by providing refuge from the flip flop flow regime change that takes place in the fall. The assessment will focus on utilizing the entire 50 acres of property along 0.5 miles of the Naches River to achieve the maximum possible benefit to fish. Work accomplished to date (PRISM # 14-1217) includes site assessments, groundwater level investigation, hydraulic modeling, preliminary designs, and a preliminary design report.
