OCWD Management Area
from MWD. Each year, a specific amount of money is budgeted to purchase imported water and, if water is not available from MWD, the funds are carried over to the next year in the Water Reserve Fund.

Available Storage Space (amount below full basin condition)
Basin Management Actions to Consider
Less than 100,000 acre-feet
Raise BPP
100,000 to 300,000 acre-feet
Maintain and/or raise BPP towards 75% goal
Seek additional supplies to refill basin and/or lower the BPP Seek additional supplies to refill basin & lower the BPP
300,000 to 350,000 acre-feet
Greater than 350,000 acre-feet
Basin Production Limitation
Another management tool that enables OCWD to sustainably manage the basin is the Basin Production Limitation. Section 31.5(g)(7) of the OCWD Act authorizes limitations on production and the setting of surcharges when those limits are exceeded. This provision can be used when it is necessary to shift pumping from one area of the basin to another. An example of this is the Coastal Pumping Transfer Program, which shifts pumping from the coastal area to inland to minimize seawater intrusion, when necessary.
10.3.4 Supply Management Strategies
One of OCWD’s basin management objectives is to maximize groundwater recharge. This is achieved through increasing the efficiency of and expanding OCWD ’s recharge facilities and t he supply of recharge water. Construction and operation of the GWRS has provided a substantial increase in supply of water available to recharge the basin. Additional OCWD supply management programs include developing increased stormwater capture programs behind Prado Dam in cooperation with the U.S. Army Corps of Engineers, encouraging and participating in water conservation efforts, and working with MWD and the Municipal Water District of Orange County in developing and conducting other supply augmentation projects and strategies.
10.4 DEVELOPING NEW LOCAL WATER RESOURCES POLICY
In July 2020, the District adopted a policy called the Developing New Local Water Resources Policy to acknowledge that the local multi-billion-dollar economy and 2.5 million citizens that rely on groundwater as their primary water supply require a reliable, sustainable and economical
