Kelsey Creek is a watercourse in Lake County, California, United States, that feeds Clear Lake from the south. Originally forest-covered, the watershed has been converted in the lower parts to farmland and for urban use. Higher up, the forests have been cleared, regrown, and cleared again. The northern part of the creek flows through a geothermal field that feeds power plants and hot springs. The wooded Cobb area in the higher part of the watershed was once home to resorts as early as the 1850s.
