The Confederated Tribes of the Umatilla Indian Reservation used this grant to design and construct fish passage improvements at two barrier culverts on Pataha Creek. Pataha Cr is a main tributary of the Tucannon R that serves as a rearing area for juvenile salmonids and is a destination for spawning adult steelhead. With passage rectification, it is expected that juvenile numbers would increase into the thousands, while adult numbers could increase to hundreds. The HWY 261 steel corregated culvert (RM 1) and HWY 12 (RM 10) concrete box culverts on Pataha Cr were designated as the 2 primary passage concerns (imminent threat) to both adult and juvenile migratory listed steelhead trout and resident redband/rainbow trout. Rectification of passage at these locations is expected to reduce migrational delays of adults returning from the ocean to spawn in the headwaters as well as enhancing juvenile seasonal migration to optimum habitat and cooler waters upstream during the summer months. The benefits of passage remedy will be realized exponentially when coupled with ongoing restoration efforts that are occurring upstream and in the immediate area. In simple terms the ongoing improvements to habitat status in Pataha Cr accomplished primarily by County Conservation Districts have created desirable habitat conditions for listed fish species; this project opened the access door and to complete the "build it and they will come" strategy. The approach for both barriers involved the construction of a roughened channel with a plunge pool stilling well maintained at the culvert outlet.
