The Tule River flows through both Tulare and Kings Counties in California's San Joaquin Valley, originating in the Sierra Nevada east of Porterville before eventually terminating at a junction with a canal from the Kings River, approximately 9 miles east-northeast of Kettleman City in Kings County. Spanning approximately 71 miles, this river system consists of three main forks—North, Middle, and South—each offering distinct fishing opportunities. The North and Middle Forks converge above Springville, while the South Fork joins the others at Lake Success. Downstream of Success Dam, the river flows west through Porterville before dispersing into agricultural irrigation and drainage channels. The river drains approximately 400 square miles of the Sierra Nevada, creating diverse habitat from high-elevation mountain streams to lower foothill waters. While the river is one of the smaller systems in the Sierra, it provides consistent fishing opportunities throughout its length, with the various forks positioned conveniently near Porterville making them popular destinations for anglers seeking both wild trout in the upper reaches and warm-water species in the lower sections.
