Lower Lake (formerly Grantville) is a census-designated place (CDP) in the southern Clear Lake region of Lake County, in northern California. Lower Lake is also an Indian rancheria of the Koi Nation people.

Geography
Lower Lake is located 4.5 miles (7.2 km) southwest of the City of Clearlake, and 13 mi southeast of Kelseyville. It is at an elevation of 1371 ft. Lower Lake was at one point the county seat; the Lake County elections of 1867 were hotly contested, with the seat moving between what is now the city of Lakeport and the town of Lower Lake. In 1870, the feud was settled and Lakeport controlled the seat. Although some believe the seat was stolen from Lower Lake, it has remained in Lakeport for over a century and is no longer a topic of concern for locals. At the 2000 census, according to the United States Census Bureau, the CDP had a total area of 7.9 sqmi, of which 7.9 sqmi was land and 0.1 sqmi (0.88%) was water.
