Water Resources Overview
Sequoia and Kings Canyon National Parks contain some 3200 lakes and ponds and approximately 2600 miles of rivers and streams. Three major rivers originate in these parks --Kings, Kaweah and Kern. These rivers provide valuable irrigation water to the rich agricultural lands in Fresno, Kern and Tulare counties as well as providing water for recreation and industrial activities outside the parks. The monitoring and maintenance of watershed health is clearly of interest not only to park managers but also to water users throughout this region.
Winter snowpack in the Sierra Nevada is a natural storage system for the precipitation that accumulates during winter months. The amount of water stored as snowpack increases through mid-April at higher elevations. Meltoff typically begins in April and continues through May or June. October is the month in which the least water runoff occurs from park watersheds. Snowfields, forests, lakes and streams collect, store, and release the water supplied from winter storms so it is available throughout the dry summers for agriculture, recreation, electrical power generation and other uses. The amount of snowpack is also important to park vegetation and wildlife. In years of low snowpack accumulation, there is less water available for plant growth (for example, many trees will produce a small annual ring in years of drought). During these drought years, reduced plant growth and fruit and seed production result in altered food production for wildlife.
Did You Know?
The small gravity-defying cave formations found in Sequoia and Kings Canyon caves are known as helictites. They form due to the capillary action of acidic solutions and are composed of the minerals calcite and aragonite.
