DESCRIPTION
The Wapato Reach Assessment project identified and prioritized salmon habitat protection and restoration needs on a 50 mile reach of the left bank of the Yakima River, from Union Gap (RM 110) downstream Mabton Bridge (RM 60). This assessment analyzed the physical and biological attributes of the Wapato Reach of the Yakima River, identified data gaps and developed a suite of projects to protect and restore channel and floodplain processes and habitats within the reach. It also developed a set of selection criteria for prioritizing and sequencing salmon recovery actions, and developed a ranked list of potential projects.
The report identified several properties that can be acquired, restored, and placed into State ownership as part of the Sunnyside Wildlife Area. Restoration opportunities included channel modification through roughened channel elements, placement of ballasted logs, removal of dikes and foreign material that limit floodplain function, side channel enhancement, and riparian revegetation. Some of these restoration opportunities are in key areas where property acquisition will significantly improve our ability to implement actions. All restoration actions identified with this assessment were reviewed and prioritized by a local technical advisory group. Fish expected to benefit from the project include spring, summer, and fall Chinook salmon, sockeye salmon, coho salmon, and summer steelhead.
The following projects were identified as high priority restoration efforts.
