California Water Supply 2024

OMWD’s potable water is imported from two major sources: the Sacramento-San Joaquin Delta via California’s State Water Project, and the Colorado River.

Above-average levels of rain and snow have filled statewide drinking water reservoirs and there are currently no water shortages anticipated in 2024. However, while the state is currently benefiting from the wet winters, it is a matter of time before dry conditions return.

The Colorado River is an important source of water for 40 million people in two countries and seven states. The amount of water taken from the river has exceeded available supplies for decades. As a result, reservoirs along the river that support Southern California, such as Lake Mead, are now at low levels.

OMWD continues to diversify our water supply sources to reduce our reliance on imported drinking water. Several projects are underway in our service area to become more drought-resilient. These include expanding our recycled water distribution system and exploring the possibility of building a brackish groundwater desalination facility. OMWD also indirectly benefits from water produced at the Carlsbad Desalination Plant.

While there currently is no water shortage, OMWD remains in Level 1 of its Water Shortage Contingency Plan and asks customers to follow several voluntary measures to reduce water waste.


Water Use Efficiency Regulations

California’s State Water Resources Control Board has adopted water use efficiency regulations. The new rules will affect how much water OMWD can provide customers. The regulations do not consider available water supplies and limits will be in effect whether it’s a wet or dry year. The water use limitations become more restrictive over time and OMWD does not anticipate an immediate impact to our customers. In the future, additional efficiency measures may be necessary to maintain compliance.
