2021 Map of Clearlake Highlands

About this map

Clearlake Highlands and Clearlake Park anchor the eastern shoreline of Clear Lake, where residential streets meet the water at Jones Bay and Jago Bay. The landscape transitions from the developed resort communities of Clearlake Riviera and Sunrise Vista to the protected wetlands of Anderson Marsh along Cache Creek. In the south, the terrain rises toward Seigler Valley, home to Seigler Springs and the Salminas Resort, reflecting the area's legacy of mineral springs and seasonal retreats. Topographic details highlight the distinct volcanic geography, including the landlocked Borax Lake and Thurston Lake, as well as prominent elevations like Bald Mtn and Sulphur Bank Ridge. These features illustrate the complex hydrology and varied settlement patterns between the shore and the interior hills near Mount Hannah Lodge.
