Surface Water Delivery Decrease and Water Conservation Target

The City of Modesto surface water allocation deliveries from the Modesto Irrigation District (MID) have decreased over the last couple of years from an average of 30 million gallons per day to at the lowest a delivery of 11.6 million gallons per day due to the ongoing drought. Because we have had near average rainfall and a better snow pack in the last hydrologic cycle, the MID has now allotted a delivery of approximately 25.7 million gallons per day effective May 2016, This allotment remains in effect through April 30, 2017 at which time the MID will re-evaluate and may readjust the delivery amounts.


Twenty years ago, the City of Modesto invested in the surface water treatment plant and that along with increased water conservation efforts has resulted in less groundwater being withdrawn each year from the aquifer. As a result, the Modesto sub basin has not suffered overdraft and this water bank is available for use now when we need it the most.

On May 9, 2016, Governor Edmund G. Brown Jr. issued Executive Order B-37-16 requiring the State Water Resources Control Board (SWRCB) to adjust its emergency water conservation regulation through the end of January 2017 in recognition of the differing water supply conditions across the state. The SWRCB is requiring cities in California to take action, making some of the regulatory conservation requirements permanent. The revised regulation was adopted by the SWRCB on May 18, 2016. On June 21, 2016, the City of Modesto submitted projections and calculations to the SWRCB requiring an enforceable minimum conservation standard of 20% reduction versus 2013. To ensure that we meet the 20% requirement, the new City of Modesto conservation target will be 25% through January 2017. The previous conservation mandate was 33%. The City believes that without any changes to the current water conservations restrictions and with the continued cooperation of the community, the new 25% reduction target will be achieved.
