Multnomah & Wahkeena Creeks - Benson Lake

This project improves adult fish passage into the site, hydrologic and geomorphic processes, stream temperatures, water quality and habitat diversity.  Specific actions being considered include placing large wood, riparian planting, culvert improvements, and altering hydrology.  The 50-acre site is located within Benson State Park in the Columbia River Gorge at Columbia River mile 135.5.  The two creeks enter the site, merge and exit to the Columbia through a culvert under Interstate 84.  The site has been degraded by land use activities over the last several decades including agricultural use, construction of transportation corridors and development of the State Park.

The project is currently in a design phase (December, 2013), with funds provided by the East Multnomah County Soil and Water Conservation District.  The project is being managed by the Estuary Partnership, in collaboration Oregon Department of State Parks.
