The Inyo County Water Department (ICWD) monitors the vegetation, soil water, and hydrology of the Owens Valley following ground-water exportation by the City of Los Angeles. The Inyo County Water Department (ICWD) assists in the implementation of the County Policy on Extraction and Use of Water, the Agreement, FEIR, MOU and Ordinance 1004 (see Resolution 99-43). Inyo County and the Los Angeles Department of Water and Power use this information to jointly manage the valley's water resources under the Inyo/Los Angeles Water Agreement. ICWD also advises the County on other water resource issues in Inyo County. In addition, ICWD conducts research and carries out saltcedar control and arid-lands revegetation programs.
