- Trinity River Channel Rehabilitation Sites: Coarse Sediment Management Activities
- Note: Tiered IS (15177) to SCH# 2008032110 This activity is considered to be within the scope of the previously certified Master EIR for channel rehabilitation and sediment management for remaining phase 1 and Phase 2 sites = State Clearinghouse #2008032110. The purpose of this Project is to restore aquatic habitat in the Trinity River by injecting coarse sediment to supplement coarse sediment removed from the system by the Lewiston Dam on the Trinity River. The project is designed to enhance aquatic habitat quality. The proposed Project would include introducing coarse sediment into the river primarily at high spring flows with heavy equipment or by using a conveyor system to carry the gravel to mid-channel locations.
