Project: Developing Restoration Strategies for Hydrologic Connectivity in Williams Creek

Description: Williams Creek, which contributes 42% of the Salt River’s fresh water flow, courses down from the upper watersheds and carries substantial amounts of sediment. Sediment deposition, flooding, and ponding continually reoccur due to hydrologic dysfunction during typical rain events. The sediment deposition and flooding are severely impacting residential property, agricultural producers, and infrastructure. The aggradation in the creek channel degrades fish habitat and passage. Funding will be use to conduct an alternative analysis and develop restoration strategies to restore the capacity and hydrologic conveyance of Williams Creek. This will re-establish ecological processes that benefit fish and other native species, improve agricultural resources, increase climate resiliency by reducing flood events, improve water quality and drainage efficiency across the floodplain, and control and maximize sediment transport capacity in the channel.
