On the west and northwest, the San Joaquin watershed borders those of rivers draining into the Pacific, while beyond almost all of the other divides lie endorheic basins, mostly of the Great Basin. To the north, a low series of ridges separates the San Joaquin River basin from that of the Sacramento River. The Coast Ranges bound the watershed on the west and borders on the drainages of the Pajaro River, Salinas River and the endorheic Carrizo Plain. On the south, the Tehachapis wall off the Tulare Basin from the Mojave Desert. To the east, the Sierra Nevada separate the San Joaquin drainage from those of multiple smaller rivers that terminate in various Great Basin lakes. From north to south, these are the Carson, Walker, and Owens Rivers. The sloping alluvial fan of the Kings River divides the northern San Joaquin Valley from the Tulare Basin.
