Kern River

About

Wild & Scenic since 1987, the Kern River cuts 170 miles through Kern County from the High Sierra to the Central Valley, delivering some of California's most technical whitewater. The Forks of the Kern section runs 15 miles of Class V to V+ through wilderness-only access — this is expert-level water that demands self-sufficiency and advanced rescue skills. Below that, the Upper Kern from Johnsondale to Fairview maintains Class IV to V difficulty, while the Lower Kern Canyon offers the most accessible runs at Class III to IV. At 1,100 CFS average with an optimal range of 400 to 2,500 CFS, the Kern responds dramatically to Sierra snowpack — the exceptional 2023 conditions put the entire system in full flood. Commercial outfitters including Kern River Outfitters and Whitewater Voyages guide the lower sections, but much of the upper river requires private permits and wilderness experience. The Kawaiisu people, known as the Southern Sierra People, inhabited these drainages for millennia before European contact. USGS gauge 11189500 tracks the main stem flows that determine whether the technical sections are runnable or survival-mode.
