Willow Creek is a stream in Madera County, California, and a primary tributary of the upper San Joaquin River. It originates in the Sierra Nevada and flows approximately 25 miles (40 km) west-southwest, descending about 7,000 feet in elevation before its confluence with the San Joaquin. Willow Creek is best known as the main inflow of Bass Lake, a reservoir in the Sierra National Forest. Along its course it features a series of cascades known as Angel Falls, a popular recreation site. The creek supports hydroelectric generation, municipal water supply, and a variety of outdoor activities.
