- Protect and Enhance Watersheds and Ecosystems that Provide Water Quality and Supply Benefits
- Respect Local Autonomy and Local Knowledge in NCRP Planning and Implementation
NCRP IRWM Prop 50 R1 (SWRCB)
Completed
Water quality and salmonid habitat in Indian, North Fork Navarro and Rancheria Creek subwatersheds in the Navarro River basin have been severely impacted by excess sediment loading from upslope sources including erosion and sediment delivery associated with networks of unimproved, poorly drained forest/ranch roads. Short-term goals: reduce anthropogenic erosion and sediment delivery by implementing erosion control and prevention treatments on properties in the Indian Creek and upper Rancheria Creek basins. Long-term goal: contribute towards salmonid habitat improvement and to promote sediment and temperature TMDL goals in the Navarro watershed.

General Information
Project Description Narrative (1,000 character limit)
Between September 2008 and October 2009, PWA supervised treatment of roads in the project area, as well as individual sites showing evidence for erosion and sediment delivery to watercourses in the Navarro River watershed. Of the 18.6 mi of roads treated, field evidence showed that approximately 9 mi of roads were “hydrologically connected,” i.e., delivering concentrated surface runoff to the stream system. Road segments were treated with road drainage treatments to disperse road surface runoff and diminish the persistent delivery of fine-grained, roadbed-derived sediment.

Project Types
Project Types
Repairing the roads improves transportation infrastructure for this disadvantaged area.
Sediment delivery reduction improves and restores salmonid habitat and overall watershed conditions.
Improving instream habitat and road infrastructure improves the watershed's climate resiliency. The improvements make the watershed and the infrastructure better able to withstand weather patterns associated with climate change.
