Document Description
Note: Extended Review Per Lead
The project, which was approved on Nov 12, 2014, and for which previous approvals remain in place, will remove sediment from Devil's Gate Reservoir to restore capacity and to protect the dam and its valves to reduce the risk of flooding in the communities located downstream. This effort will include removal of approx 2.4 million cy of existing excess sediment in the reservoir in addition to any additional sediment that accumulates during construction. Sediment removal activities are expected to occur over the course of approx 3-5 years beginning summer 2018. Reservoir management is expected to start after 2022. The purpose of the annual reservoir management is to reduce buildup of sediment in the management area and eliminate or substantially reduce the occurrence of another large scale sediment removal project in the future.
