The Lower Walla Walla River is delineated as being the river miles downstream from the confluence of Pine Creek, or the river miles below the Walla Walla MSA. This river reach is not designated by NOAA as a major spawning area for salmon, and has no priority designation for protection or restoration in the Snake River Salmon Recovery Plan. Limiting factors in this reach have not been identified with the exception of Imminent Threats. Imminent Threats are identified as conditions which pose a direct threat toward listed fish, including but not limited to fish passage barriers, fish screening projects, and water quality and quantity. The Walla Walla County Conservation District (WWCCD) working with the Confederated Tribes of the Umatilla Indian Reservation and the Tri-State Steelheaders have addressed all known fish passage barriers and most unscreened irrigation diversions in this reach.
The SRSRB has supported some restoration projects within this reach, but its main focus is on the upper river where projects will have the greatest impact on spawning and rearing habitat. This is planned to continue in upcoming years. The SRSRB and the SRSRB Technical Team are the guiding body directing restoration priorities and will be the group reasoning future needs in the lower river.
