About this map

The western shores of Clear Lake anchor this 1994 map, showing the established communities of Lakeport and Kelseyville alongside the expansive waters. The landscape transitions sharply from the deep blue of the lake and the agricultural patterns of the Sacramento River valley to the east, into the high peaks of the Mendocino National Forest. Significant mercury and sulfur mining history is represented here at sites like the Sulphur Bank Mine and Abbott Mine, marking the region's geological and industrial heritage.

Conservation areas and water management systems define much of the territory between the coast range and the valley floor. Large-scale infrastructure like the Indian Valley Reservoir and the Colusa Basin Drainage Canal sit alongside protected lands including the Snow Mountain Wilderness and the Sacramento National Wildlife Refuge. The transportation network is anchored by Interstate 5 and the Southern Pacific RR, which helped connect the valley settlements of Williams and Colusa to the broader California economy.
