The Naneum, Wilson, and Cherry Creek Assessment was initiated to assess existing conditions within the named three watersheds and to work toward development of a long-term watershed management plan to address fish habitat needs, flood hazard reduction, infrastructure, and irrigation in streams and ditches north and east of the City of Ellensburg. The watersheds cover 394 square miles and include 14 tributaries originating in the uplands and shrub steppe and then flowing through irrigated agriculture land and two cities before discharging through a single point of discharge to the Yakima River. Most streams within the three watersheds have been significantly altered to accommodate development, irrigation, and transportation infrastructure, and to reduce flooding. This assessment focused on the valley floor portions of the three watersheds. The assessment relied on frequent and meaningful communication between stakeholders, which included landowners, state and federal agencies, local governments, irrigation districts, and non-profit organizations. Kittitas County compiled, analyzed, and mapped large datasets of existing information on stream and irrigation canal locations, transportation and irrigation infrastructure, fish use, stream habitat, fish habitat, fish passage barriers, stream flow, stream temperature, surface water diversions, and water rights. They monitored stream flow and temperature at ten locations for two years, mapped areas of overhanging vegetation along streams, identified locations of invasive Crack Willow trees, and modeled 2 year and 100 year flood events. The original proposal included in-stream inventories of fish passage barriers, stream habitat, and fish surveys above and below passage barriers. However, the technical advisory group determined that fish presence information was a secondary task and could be acquired after developing an understanding of the limiting factors for fish presence (flow and temperature). Additional habitat data based on planned stakeholder field work was not collected due to drought conditions and competing priorities. Kittitas County utilized collected data to identify data gaps, develop a matrix to select optimum routes to restore fish passage to the upper Naneum Creek watershed, and make recommendations for projects or actions that should be pursued immediately, ongoing actions that should continue, and future actions that should be undertaken with additional planning or study. The project is intended to benefit steelhead, Chum Salmon, and spring-run Chinook Salmon. This assessment was a critical first step in understanding how these streams interact as they flow across a sometimes steep alluvial fan floodplain. Determining the tributaries to the tributaries and the directions they flow together only to split apart and reconnect was an informative exercise in the workings of alluvial fan stream systems. These complex flow patterns and interactions are further complicated when water rights points of diversion and points of return are considered. This project was Phase 1 of a project that will continue to grow as we sort through priority actions. More detailed information can be found in the attached assessment report dated 6-29-17.
