San Felipe Creek is a stream in Imperial and San Diego Counties of California. It arises in the Volcan Mountains of San Diego County 33°11′57″N 116°37′35″W / 33.19917°N 116.62639°W, and runs eastward, gathering the waters of most of the eastern slope of the mountains and desert of the county in the San Sebastian Marsh before it empties into the Salton Sea.[1] It is probably the last remaining perennial natural desert stream in the Colorado Desert region.[2][3] In 1974, the San Felipe Creek Area was designated as a National Natural Landmark by the National Park Service.[4]
Parts of the land around the creek are owned by the Bureau of Land Management (classified as an Area of Critical Environmental Concern) and the California Department of Fish and Wildlife (as a Ecological Reserve.[5][6]
