Helm Canal
From Wikipedia, the free encyclopedia
The Helm Canal (Latitude: 36.877N; Longitude: 119.734W) is a man-made waterway for conveyance of water in Clovis, California, USA.[1] The Helm Canal is involved in a series of water transfers to eliminate selenium bearing brackish waters to the San Joaquin River to bypass agricultural deliveries.[2]
The Helm canal previously was used to irrigate numerous properties that were previously in agricultural usage and are presently converted to urban uses such as the site of the Clovis Towne Center.[3] Topography in the locale of the Helm Canal is generally very level having been formed by alluvial fans. The elevation in the vicinity of the Helm Canal is approximately 350 to 375 feet above mean sea level datum.[4]
