Kings River (California)
During the first half of the 20th century, the Kings River was the focus of a political fight over Los Angeles' proposal to dam the Middle and South Forks for power generation. Local farmers feared the city's real intention was to divert Kings water south, as it had gained notoriety for doing in the Owens Valley water wars. The KRCD, however, also wanted to dam these rivers for irrigation, and thus the proposed dam sites were excluded from Kings Canyon National Park as designated in 1940. It was not until 1965 when these areas were finally added to the park, ending a debate which had lasted more than sixty years. Today, the fall from the head of the South Fork to Pine Flat Reservoir remains the longest undammed drop of any U.S. river.
