Cole Creek Flooding | Lake County residents demand action

Who We Are

We're a community of neighbors in Green Acres, Kelseyville, California. Many of us have lived here for decades, witnessing the situation worsen significantly in recent years. Floodwaters now remain on our properties for more than 6 months each year, damaging homes, roads, and severely impacting daily life and the local ecosystem.

Decades of Neglect

Cole Creek was rerouted and channelized in the late 1950s. Since then, Lake County has performed almost no maintenance, allowing sediment and debris to accumulate. This negligence has turned Cole Creek into a flooded disaster, trapping residents and wildlife alike.

Endangered Fish, Ongoing Crisis

Cole Creek is vital for the survival of the endangered Clear Lake Hitch, yet thousands of fish still die every spring in stagnant floodwaters. Despite recognizing this crisis for years, Lake County authorities delayed crucial action. Through ongoing community collaboration (monthly meetings, detailed documentation, and consistent communication about the issues), the county published a comprehensive planning RFP in September 2025 and is now working to finalize a contract, marking the first concrete step toward long-term restoration.

Lake County selects FlowWest for Cole Creek restoration planning

Lake County selected FlowWest to plan and design the restoration of Cole Creek. This is the $200,000 to $500,000 planning contract we’ve been waiting for (Task C of the September 2025 wildlife RFP). The money funds the engineering and water flow studies to restore a 1.55-mile stretch of the creek. This is a major step toward fixing the bottlenecks that flood our neighborhood and clearing the way for spawning Clear Lake hitch.

Public comment on the Lake County 2050 General Plan

The draft Lake County 2050 General Plan is out for public review. This is the county's blueprint for the next 25 years. It decides where funding goes and which projects get built. The drafts name Cole Creek as a "primary source of flooding," but stop there. They don't recognize the Cole Creek Collaborative's work or mandate the fixes we need. We submitted a public comment pushing for concrete changes: priority funding for Green Acres, mandated channel maintenance, evacuation-constrained mapping for our flooded roads, and the Collaborative as the county's template for restoring channelized creeks.

Clear Lake hitch spotted spawning in Cole Creek during community survey

We counted about 50 Clear Lake hitch in Cole Creek on March 10 during a community survey for the county. The spawning run kicked off around the same time, which is great to see after years of channel problems.

Progress and Continued Need

While long-term planning moves forward, recent cleanup efforts have made a difference. California Conservation Corps crews cleared vegetation from the channel in December 2025, and county workers separately removed vegetation and sediment upstream of Clark Drive Bridge in August 2025. Yet much of the creek remains clogged. Consistent maintenance (cutting vegetation, removing debris, and keeping the channel open) is essential to protect homes, roads, and wildlife while the multi-year restoration project develops.
