| Description | Mid-Columbia Fisheries Enhancement Group (MCF) will conduct an assessment of temperatures and water levels associated with anthropogenic and natural influences on an historic oxbow at river mile 25 on the lower Yakima River. Temperature loggers and level sensors will be used to continuously monitor temperatures and water levels, respectively, within a partially disconnected oxbow and its associated side channel as well as the adjacent mainstem Yakima River. The oxbow channel is no longer connected to the river at its upstream end, but still conveys water through a downstream outlet from at least two springs within the oxbow. This provides a potential source of warmer winter and cooler summer water for the Yakima River. The adjacent northerly side channel is fully-connected to the river, and is impacted by sediment accumulation and water stargrass colonization. The side channel and springs were included in the description of river features identified as high priorities for enhancement in the Assessment of the Lower Yakima River in Benton County, Washington (Appel et al., 2011). The objective of the Yakima River Side Channels Project assessment is to determine how this oxbow and associated side channel can be enhanced to provide pockets of higher quality habitat for salmon and steelhead. Temperature and stage data will inform engineering design of side channel enhancement. Additionally, substrate condition in the connected side channel will be assessed to determine its suitability for salmon spawning. |
