IMPLEMENTATION OF A MUTI-PARTNER, COLLABORATIVE EFFORT TO MANAGE AND MONITOR POST-FIRE WATER QUALITY IN A LARGE NORTHERN CALIFORNIA LAKE.

During summer 2018 the Mendocino Complex wildfire burned over 450,000 acres, geographically the largest fire in California’s post-settlement history. The burn scar was mostly located within the upper watershed of Clear Lake, a 303(d) listed nutrient impaired waterbody in Lake County and the state’s largest freshwater lake. Not only is Clear Lake home to sensitive floral and faunal species and supports traditional Native American uses, but Clear Lake provides drinking water to 40,000 residents and activities such as fishing and recreational boating generate substantial tourism dollars. A multi-partner, interagency collaborative post-fire action plan was immediately implemented to identify 1) locations most likely to contribute post-fire pollutant and sediment loads 2) locations most likely to benefit from on-the-ground best management practices to limit post-fire impacts and, 3) best stream and lake sample sites to monitor post-fire water quality. This paper will discuss development of this effort, specific actions implemented, outcomes, and status of Clear Lake. Conclusions from this effort might be useful to organizations and agencies when partnering and collaborating on management and monitoring in freshwater systems with large or impaired waterbodies, of which current post-fire water quality research is limited.
