The shallow basin below Santa Margarita is the only water source for the community, and the County has developed a program to help protect the water supply and avoid the need for mandatory measures. The levels of response described below are required to protect the supply and minimize impacts to the community.

• When the average rainfall and groundwater levels are at or near normal levels, the status is OK. Residents are entitled to all the water they can put to reasonable and beneficial use.

• If the groundwater drops below normal levels and the supply appears to be at risk, then the water supply status is ALERT. An ALERT status requests that all residents and business owners in Santa Margarita voluntarily reduce their water usage.

• If the groundwater drops significantly below normal levels and the supply appears to be at risk, then the water supply status is CRITICAL. During a CRITICAL status, mandatory conservation measures would be implemented.
