As part of the Trinity River Restoration Program (TRRP) channel rehabilitation activities to improve fishery habitat, the Bureau of Reclamation and Bureau of Land Management (co-lead federal agencies); U.S. Forest Service (cooperating federal agency) and the North Coast Regional Water Quality Control Board (state lead agency), propose to construct the Chapman Ranch Phase B channel rehabilitation project in 2021.
A Finding of No Significant Impact was signed for the Chapman Ranch Phase B project.
The environmental document that formally analyzes the impacts of this proposed project, and which meets California Environmental Quality Act (CEQA) and National Environmental Policy Act (NEPA) requirements is available here: https://www.trrp.net/library/document/?id=2466.
The TRRP, Bureau of Reclamation, Bureau of Land Management, Shasta-Trinity National Forest – U.S. Forest Service (federal agencies), and the North Coast Regional Water Quality Control Board (Regional Water Board – state lead agency) propose to construct the second phase of its Chapman Ranch Phase A river restoration project near Junction City, CA, called the Chapman Ranch Phase B Project (Phase B). The Chapman Ranch Phase B channel rehabilitation restoration site is immediately upstream of the Phase A site and is located approximately 3.5 miles south (upstream) of Junction City, between river miles (RM) 83.5 and 83.8.
The proposed project spans 63 acres, primarily managed by the USFS (29 acres) and the BLM (27 acres). Phase B would be accessed via Sky Ranch Road on river right and Dutch Creek road on river left.
The Phase B project is designed to interface with the 2019 Phase A project to increase the size and improve the overall function of the restoration area. The completed Chapman Ranch project would:
- Reestablish a function, topographically-complex floodplain to increase river connections at a greater range of flows and promote dynamic river processes.
- Increase in-channel habitat diversity at all flows by placing wood to interact with river flows, provide cover for fish, and increase channel complexity and groundwater retention.
- Revegetate construction-disturbed upland and riparian habitats to restore native plant diversity and fish and wildlife habitat, and provide future trees for recruitment to the river.
