Document Description
Note: Review per lead The proposed project would remove up to 4.0 million cubic yards of sediment from the reservoir behind Devil's Gate Dam to restore it to its current design standard, and establish a reservoir configuration more suitable for routine maintenance activities including sediment management. A specific excavation boundary within the project boundary, ultimate reservoir configuration, and volume of sediment to be removed within the boundary will be determined based on locations of access roads; areas for preservation or restoration of native vegetation; and the amount and location of sediment inflow that occur during the upcoming storm seasons. The proposed project is expected to occur between Spring 2014 and Winter 2019.
