The Coachella Valley gets almost no rain. The golf courses, resort hotels, date groves, and cities that cover its floor exist because a water district, founded on January 9, 1918, claimed water rights, built infrastructure, and has been managing that infrastructure through continuous drought and population growth ever since. The district's first official act was claiming rights to the Whitewater River — a declaration of intent from a new institution that understood its entire reason for existing was water that didn't naturally fall where it was needed.
The Coachella Branch of the All-American Canal is 123 miles long and carries Colorado River water to the valley by gravity alone — the canal drops one foot per mile across the entire length. This means no pumping stations are required for the primary conveyance, an engineering advantage that also makes the system vulnerable to elevation changes and terrain. The canal delivers water drawn from the Colorado under the district's 450,000 acre-feet annual entitlement, established in the 2003 Quantification Settlement Agreement. Combined with the district's massive groundwater basin — the aquifer holds 39.2 million acre-feet, among the larger reserves in California — the system supports 76,350 acres of agricultural land and a residential population drawing 90.4 million gallons per day.
More than $730 million in crops are produced annually on the agricultural land the district irrigates — a figure that makes the eastern Coachella Valley's agricultural economy one of the most productive per acre in California. The primary date crop, responsible for nearly 95 percent of American date production, depends entirely on the district's irrigation. So do the table grapes, citrus, peppers, and other crops that employ the farmworker communities of the eastern valley. The district covers approximately 1,000 square miles of territory, from the San Gorgonio Pass in the northwest to the Salton Sea in the southeast, serving the full range of uses from luxury golf courses to small family agricultural operations.
Water management in the Coachella Valley extends well beyond delivery. The district operates five wastewater treatment plants and more than 1,100 miles of sewer infrastructure — a system that handles the effluent from the 320,000 people it serves and manages its treatment in a desert environment where evaporation and groundwater recharge intersect in complex ways. Treated wastewater is increasingly used for agricultural irrigation and golf course watering, reducing pressure on the district's potable water supplies. The combination of Colorado River imports, groundwater banking, and water recycling represents a layered system that has allowed the valley to sustain uses that its natural hydrology would not support — and that the district's founders in 1918 could not have fully imagined.
The Coachella Valley Water District serves the entire Coachella Valley, headquartered at approximately 33.67°N, 116.17°W in the city of Coachella. The valley's agricultural landscape — visible from the air as a geometric grid of irrigated fields, date palm groves, and golf courses against surrounding desert — is entirely dependent on the district's water delivery system. The Coachella Branch of the All-American Canal is not visible from altitude along most of its route, but the agricultural fields it serves are the dominant visual feature of the valley floor. Palm Springs International Airport (KPSP) serves the western valley; Jacqueline Cochran Regional Airport (KTRM) serves the eastern valley and agricultural communities directly.
