Project: Rancheria Creek Stream Flow Enhancement and Restoration

Description: A grant to the Dry Creek Rancheria Band of Pomo Indians (Tribe) for a cooperative project with the Federal Highway Administration, U.S. Environmental Protection Agency, U.S. Fish and Wildlife Service, and Bureau of Indian Affairs to implement 16 restoration actions. These actions, designed to enhance flows and improve ecological conditions and geomorphic processes, span a project area of 91± acres within the Dry Creek Rancheria, and will improve and restore habitat for endangered steelhead and Coho salmon in Rancheria Creek. The project includes ecological improvements, riparian restoration, flow enhancement actions and expansion of a detention basin. Ecological improvements include excavation of floodplain benches in an existing incised channel to restore floodplain function and hydrology conditions; channel realignment to restore habitat complexity in the channelized reach of the creek; replacement of culverts that restrict fish passage; planting of riparian vegetation along the channelized portion of the creek to create cover to shade the creek and create a riparian buffer from the existing vineyard operations; and bank stabilization along the Russian River. Riparian restoration along the creek will remove invasive species and re-vegetate with native shade and cover producing plants and trees. Flow enhancement actions include installation of an off-stream storage tank fed by the onsite waste water treatment plant to supplement flow in Rancheria Creek during the critical summer period for steelhead and Coho. A detention basin will also be expanded and will contribute to flow enhancement by capturing and storing storm runoff for controlled release to the creek. Both the tank and the detention basin will discharge to the creek through vegetated and rocked swales to reduce erosion. Invasive, non-native Arundo will be removed and replaced with native riparian vegetation to increase the water in the creek and Russian River.
