The Kaweah River just below the confluence of its forks, flowing through the drained Lake Kaweah bed (note the light brown "bathtub ring" on the valley slopes). This segment of the river is routinely submerged during high water in the springtime but is usually above the water.

The Kaweah River is an approximately 58.5-mile (94.1 km)-long river in the U.S. state of California. It rises in four major forks in the Sierra Nevada within Sequoia National Park, flowing southwest through the Lake Kaweah reservoir and onto an alluvial plain northeast of Visalia. Formerly the river continued southwest to empty into Tulare Lake, the terminal sink of an endorheic basin in the southern Central Valley. However, the river is heavily diverted for irrigation water, and its lower reaches are dry for most of the year.
The foothills of the Sierra around the Kaweah River were once inhabited by the Yokuts people. The name "Kaweah" is thought to mean "crow" or "raven cry" in the Yokuts language. Shoshonean people from the Great Basin later settled in the high valleys of the Kaweah's forks. In the 1870s, a short-lived silver boom took place in the Mineral King valley of the river's East Fork, attracting settlers to the region. The majority of the Kaweah's headwaters above the Central Valley became part of Sequoia National Park in 1890. The southeastern part of the river's watershed also became part of the park in the 1970s after a failed proposal for a massive ski resort. The Kaweah River is now a popular destination for hiking, fishing and whitewater rafting.
The Kaweah River rises in the southernmost part of the Sierra Nevada and flows southwest into the dry endorheic basin of the southern San Joaquin Valley, as do the Kings, Tule, and Kern Rivers, which all begin in or near Sequoia National Park. There are five primary forks to the Kaweah River: the Middle Fork, East Fork, North Fork, South Fork and Marble Fork, ordered by size. The Middle Fork, the largest tributary and sometimes considered the main stem of the Kaweah River, rises along the Great Western Divide, fed by a series of lakes, springs and snowfields. The river flows west, passing Moro Rock and crossing underneath California State Route 198, more commonly known as the Generals Highway (the main road through Sequoia National Park) between the confluence with Paradise Creek and the Marble Fork. It receives the Marble Fork from the right, forming the Kaweah River proper, which soon receives the East Fork from the left near Three Rivers.
The river continues southwest to the confluence with the North Fork from the right, then the South Fork enters from the left just before Lake Kaweah, formed by Terminus Dam, impedes the river’s course. After passing out of the dam, the Kaweah receives Dry Creek from the right then curves south through farmland past the town of Lemon Cove. Cottonwood Creek enters from the right and Yokohl Creek from the left. The river then splits into distributaries, including the St. Johns River and Deep Creek. The main channel continues southwest, joining with the Tule River. In wet years, the river occasionally reaches the now-dry Tulare Lake bed, which even emptied into the San Joaquin River during extreme floods through forks of the Kings River.
Snowmelt from the high Sierra Nevada, along the 13,000-foot (4,000 m)-high Great Western Divide, feeds the Kaweah River, which can reach enormous peak flows in the spring and early summer and shrink to a trickle by late autumn. The river's average flow at the U.S. Geological Survey stream gauge near Three Rivers is 554 cu ft/s (15.7 m3/s), with a maximum of 1,680 cu ft/s (48 m3/s) in May and a minimum of 57 cu ft/s (1.6 m3/s) in September. The highest recorded peak was 80,700 cu ft/s (2,290 m3/s) on December 23, 1955.
Natural history 
The watershed has numerous flora and fauna species, with considerable forested reaches. In the 1909 survey by Willis Linn Jepson there were found to be 20,000 trees (5000 of which were large trees) in the Marble Fork of the Kaweah River. There are also numerous wildflower species including the iconic Yellow Mariposa Lily, Calochortus luteus, which has been specifically noted in the Lime Kiln Creek tributary watershed. The Kaweah River is famous for its stands of giant sequoias, which were one of the reasons for the establishment of the national park. The giant sequoia are native to the western slopes of the Sierra Nevada, and they are especially abundant in the South Sierra, where the Kaweah River flows.
The first inhabitants of the Kaweah River watershed were the Yokuts, who claimed water rights to the entire river. They settled in several villages in the broad, arid valley the Kaweah cuts through the foothills of the Sierra Nevada, an area now submerged under Lake Kaweah. The meaning of the word "kaweah", pronounced "ga-we-hah", in the ancient Yokuts language is "crow" or "raven cry". The Yokut sub-tribe called the Wukchumni lived in this area; their largest villages included Cobble Lodge at the confluence of the Kaweah River and Horse Creek, and Slick Rock Village further upstream. The Fawia, Telamni, Wolasi, Choinok, and Yokod lived on the lower reaches of the river above Tulare Lake.
The Yokut subsisted mostly on acorns and the cakes and pastes they made from grinding them. Many of the Yokuts' mortar and pestle sites are still visible today in the form of rounded depressions on granite outcrops along the river. They claimed the water rights of the entire Kaweah, although tribes from the Mono Basin east of the Sierra Nevada came over the Sierra and settled in the high mountain valleys of the Kaweah. Mineral King, a valley on the East Fork Kaweah River, was a summer settlement for the Yokut. However, years before the arrival of Europeans, the valley became taboo to them for an unknown reason.
Spanish explorers named the river Rio San Francisco and Rio San Gabriel while early American settlers often referred to the river as the River Francis. The first known European settler along the Kaweah river was Hale Dixon Tharp in 1856. He settled on Horse Creek near its confluence with the Kaweah River. During the 1860s, other stockman settled along the various forks of the river claiming large areas of land under the Homestead Act of 1862. This act allowed a settler to occupy 160 acres (0.65 km2), or 320 acres (1.3 km2) for a man and wife together. Thus began the settlement of the Kaweah region. Since then, various mining towns (mainly due to the discovery of silver at Mineral King) and small establishments have existed in the area.
There is some fishing and rafting on the river, but access is difficult because some of the land is privately owned, particularly in the lower portion. There are several companies that offer day trips on the class IV section. The Kaweah River is free-flowing above Lake Kaweah and depending on the winter snowfall, it can rise to very high flows during the spring. It is best if rafters and kayakers have previous experience running class IV because with the fluctuating flows, the river requires great maneuvering and whitewater skills.
