Boggs Lake Ecological Reserve

Boggs Lake Ecological Reserve is a 46-acre protected area in Lake County featuring a volcanic lake that fills with rainfall during wet seasons and gradually dries in summer. The lake sits in a volcanic depression covered with fine ash, creating a natural water barrier.

The reserve was established in 1973 and takes its name from Henry C. Boggs, who operated a mill near the lake in 1866. The volcanic geology and seasonal water cycle have shaped this landscape for thousands of years.

Local conservation groups and scientific researchers conduct regular studies of endangered plant species and monitor the western pond turtle population.

The reserve is accessed from Highway 175 near Kelseyville via Bottle Rock Road, continuing south to Harrington Flat Road. Visitors should plan around seasonal water levels, as the lake's condition changes dramatically throughout the year.

The reserve hosts a rare ecosystem with endangered plant species and a western pond turtle population that receives ongoing scientific attention. Conservation groups conduct regular studies to monitor this fragile habitat.
