Project Stage
Completed
Duration
2008 - 2009
Solutions
Climate Action - Adaptation, Community Health and Safety - Community Infrastructure, Community Health and Safety - Fire-Safe Roads, Ecosystem Conservation and Restoration - Water
HEALTHY ECOSYSTEMS, HABITATS AND SPECIES Conserve and Restore Salmonid Habitats and Ecosystems
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.
