Bagley Valley Watershed Restoration

Bagley Valley Watershed Restoration Project / USDA Humboldt-Toiyabe National Forest

From the spring of 1998 until the fall of 2000, the RCI restoration team worked with US Forest Service specialists in all phases of stream and watershed restoration. The restoration team inventoried, analyzed and surveyed the functional condition of the watershed, designed special stream restoration treatments, produced plans and special details, developed construction documents, and completed the environmental documentation required for NEPA, CEQA and Sections 401 and 404 of the Clean Water Act. The design report included results from cultural resource, vegetation, hydrologic, soils, and wetland investigations. Plans included native plant salvage and propagation for revegetation; special treatment details, construction access and phasing plans, temporary erosion control, temporary stream re-routing, road re-alignment, and construction. This project required Proper Functioning Condition Analysis and Rosgen Stream Classification.

The Bagley Valley watershed is approximately 6,400 acres (10 square miles) in size, the main stream channel is 3.6 miles long and the elevation ranges from 6,400 to 7,800 feet. In order to avoid the risk of significant soil erosion due to construction activities, construction of the project was phased in over several years. RCI worked closely with the US Forest Service specialists in selecting the restoration techniques that will have the greatest success and benefit to the watershed while minimizing the risk and disturbance. Restoration included new channel construction, spot bank stabilization, revegetation, road reclamation, road design and re-contouring.
