Urban Water Wholesaler Supply Information

On May 9, 2016, Governor Edmund G. Brown Jr. issued Executive Order B-37-16, requiring the State Water Board to adjust its emergency water conservation regulation through the end of January 2017. The Board adopted the revised regulation on May 18.

In addition, the State Water Resources Control Board adopted a statewide water conservation approach that replaces the prior percentage reduction-based water conservation standard with a localized “stress test” approach.

This self-certification would include information provided by wholesale suppliers about how regional supplies would fare during three additional dry years. Both urban water suppliers and wholesale suppliers are required to report the underlying basis for their assertions, and urban water suppliers are required to continue reporting their conservation levels.

Urban water wholesalers are defined in the regulation as “a wholesaler of water to more than one urban water supplier.” As an urban water wholesaler, SGVMWD is required pursuant to Section 864.5(g) to provide projections on the amount of water that is expected to be delivered to retailers based on a three-year water supply projection that assumes current supply conditions plus an assumed hydrology based on the 2012-’13, 2013-’14 and 2014-’15 water years.

Estimated Supply

2017

(2013 hydrologic conditions)

2018

(2014 hydrologic conditions)

2019

(2015 hydrologic conditions)

State Water Project

14,989 acre-feet*

 

1,440 acre-feet

5,760 acre-feet

 * Based on 2013 hydrologic conditions the San Gabriel Valley MWD’s projected supply would be 10,800 acre-feet (35% State Water Project Allocation). Due to our supply and projected use in 2016, as seen below, the estimated supply amount to be carried forward to 2017 would be 4,909 acre-feet.

San Gabriel Valley MWD 2016 supply:

State Water Project (60% allocation)

17,280 acre-feet

Cyclic Storage

2,236 acre-feet

TOTAL

19,516 acre-feet

 

San Gabriel Valley MWD 2016 projected use:

Main San Gabriel Basin Watermaster replacement obligation

9,607 acre-feet

Sierra Madre/MWD Exchange Agreement

5,000 acre-feet

TOTAL

14,607 acre-feet

 

San Gabriel Valley MWD hence has 14,989 acre-feet remaining for 2017, calculated as follows:

SGVMWD 2016 Supply

19,516 acre-feet

SGVMWD 2016 Projected Use

-14,607 acre-feet

2017 Projected Supply (2013 hydrologic conditions)

10,080 acre-feet

TOTAL

14,989 acre-feet

 

Analysis used to calculate information provided:

  • The San Gabriel Valley Municipal Water District (The District) currently receives 100% of its supply from the State Water Project.

Notes:

  • The District provides water at the request of the Main San Gabriel Basin Watermaster (Watermaster) for replenishment of groundwater   overproduction by its four member cities - Alhambra, Azusa, Monterey Park and Sierra Madre. The cities’ ability to produce needed groundwater in a given year is not limited by the Districts ability/inability to replenish overproduction of groundwater as necessary to meet the cities' supply needs/demand from previous years. The District can provide the water to Watermaster when it becomes available, and Watermaster will not prevent the cities from pumping water as necessary to meet the cities' supply needs/demand in the interim.
  •   The District does not provide direct delivery of water to any of its four member cities.
  • The Cities of Alhambra and Sierra Madre currently receive direct delivery from the Metropolitan Water District of Southern California (MWD). The District then returns this water to MWD through exchange agreements related to those two cities. The District through its State Water Project allocation and current water in storage has sufficient supply to maintain these exchange agreements for 2017 to 2019.
