Tule River (Calif.)

The Tule River, also called Rio de San Pedro or Rio San Pedro, is a 71.4-mile (114.9 km) river in Tulare County in the U.S. state of California. The river originates in the Sierra Nevada east of Porterville and consists of three forks, North, Middle and South. The North Fork and Middle Fork meet above Springville. The South Fork meets the others at Lake Success. Downstream of Success Dam, the river flows west through Porterville. The river used to empty into Tulare Lake, but its waters have been diverted for irrigation. The river reaches Tulare Lake during floods. Tulare Lake is the terminal sink of an endorheic basin that historically also received the Kaweah and Kern Rivers as well as southern distributaries of the Kings.
