This project is located on Simmons Creek. The upper reaches of Simmons Creek are located on a relatively flat plateau with deep, fine-grained soils. At least a 6,600 linear foot length of the stream is moderately to deeply incised. The condition is probably due to a combination of historic agricultural clearing and ditching and past intensive grazing. Erosion and downcutting occurs in these streams during high flows, as water is unable to spread onto the floodplain. Rapid runoff results in poor groundwater recharge, exacerbating low, warm summer flows in downstream reaches of Snyder Creek, which contains spawning and rearing habitat for ESA-listed Middle Columbia steelhead.
The proposal is to build approximately 40-50 channel roughness/sediment capture structures and off-stream cattle watering systems within the 6,600 linear foot stream segment of Simmons Creek. Structure installation will be accomplished under the guidance of the District Engineer and WDFW’s Integrated Streambank Protection Guidelines. Riparian plantings of willow, black cottonwood, and other species will be included. The objective is to use wood, vegetation, and small rock to add channel roughness, stabilize eroding banks, increase groundwater recharge, reduce downstream sedimentation, and increase summer flows in downstream salmonid habitat.
A rapid assessment will be conducted to evaluate sediment budget in the area which will lead to future projects in the basin.
