The Watering Index is a recommended setting for wise water usage. Set your sprinkler controller's "budget adjustment" to 100% for the hottest months of the year, and a lower percentage for cooler months.
ACRE-FOOT (AF)—A common water industry unit of measurement. An acre-foot is 325,851 gallons, or the amount of water needed to cover one acre with water one foot deep. An acre-foot serves annual needs of two typical California families.

ADJUDICATION—A court determination of water rights for a groundwater basin or a stream; adjudication sets priorities during shortages.
AQUIFER—An underground geologic formation of rock, soil or sediment that is naturally saturated with water; an aquifer stores groundwater.
CONJUNCTIVE USE—Storing imported water in a local aquifer, in conjunction with groundwater, for later retrieval and use.
CUBIC FOOT—A frequent water industry term of measurement, as in cubic feet per second. One cubic foot (cf) equals 7.48 gallons. A cubic foot per second is 450 gallons per minute.
DISCHARGE—the amount of water flowing past a location in a stream/river in a certain amount of time – usually expressed in liters per second or gallons per minute.
EIR—Environmental Impact Report; a state-mandated written summary of the positive and negative effects on the environment caused by the construction and operation of a project.
GROUNDWATER—Water that has percolated into natural, underground aquifers; water in the ground, not water puddled on the ground.
GROUNDWATER RECHARGE/REPLENISHMENT—Pumping or percolating storm water runoff or imported water into an aquifer to replenish its supplies.
IRP—Integrated Water Resources Plan. The district’s plan to ensure reliable water delivery to its customer member agencies despite population growth, dry spells and droughts. The IRP resources mix includes water storage, conservation, best management practices (BMPs), recycling, desalination, and groundwater recovery, among others.
MEMBER AGENCY—One of 26 member public water providers associated with the Metropolitan Water District of Southern California, from which it purchases water and on whose board it is represented.
MUNICIPAL WATER DISTRICT—A public water provider governed by a locally elected board of directors, which supplies water to the public directly or through subagencies.
RECHARGE—Replenishing an aquifer with stormwater or imported water
RECLAIMED WATER—Wastewater that has been cleaned so that it can be reused for most purposes except drinking.
RECYCLED—Wastewater cleaned for re-use, usually for nonpotable purposes such as irrigating landscape and refilling aquifers.
RUNOFF—Liquid water that travels over the surface of the Earth, moving downward due to the law of gravity; runoff is one way in which water that falls as precipitation returns to the ocean.
SURFACE RUNOFF—Water flowing along the ground into rivers, lakes and oceans.
WATERSHED—A geographical portion of the Earth’s surface from which water drains or runs off to a single place like a river; also called a drainage area.
The Upper San Gabriel Valley Municipal Water District (Upper District) is celebrating six decades of innovation, conservation, and good water management. Upper District was formed by the voters on December 8, 1959 to help sustain adequate imported water supplies for the rapidly growing San Gabriel Valley.
Upper District’s Board of Directors held their first meeting on January 7, 1960 in Temple City. For the past 60 years, we have played a vital role in supplementing local water supplies with imported water from the State Water Project and replenishing the Main San Gabriel Groundwater Basin. Today, Upper District has taken a leadership role in educating the public on their local water supply and the benefits of long-term, sustainable water efficiency practices.
It is with this in mind that Upper District is proud to release our new water supply educational video for public use. We take great pride in the collaborative work that the local water agencies undertake to manage the Main San Gabriel Groundwater Basin. Thanks to several key local, regional and federal agencies in the water community, every time you turn on the faucet you are tapping into a complex water delivery system.
So, where does our water supply come from?

Phillip D. Hawkins was seated today as a member of the Metropolitan Water District’s Board of Directors.
Hawkins returns to Metropolitan’s 38-member board, where he has represented Central Basin Municipal Water District for four different terms at various times between 2003 and February 2019. Hawkins follows Frank Heldman, who joined the board in March 2019. He will serve on the board’s Audit and Ethics and Finance and Insurance committees.
Hawkins was re-elected to his fifth term on Central Basin’s board in November 2016, representing the cities of Artesia, Bellflower, Cerritos, Hawaiian Gardens, Lakewood, Paramount and Signal Hill. He chairs the Central Basin Administration & Ethics Committee and actively participates in the Colorado River Water Users Association, the Urban Water Institute and the California Contract Cities Association.
The Metropolitan Water District of Southern California is expanding its effort to learn more about the water supply potential of local stormwater capture with a new $7.5 million pilot program approved today by its board of directors.
By funding construction of new stormwater projects and installation of monitoring equipment on existing ones, the program will gather data on the amount of water produced by projects that capture local rainfall and stormwater runoff and use it to recharge groundwater basins in the region.
“This could mark the beginning of a host of new local supply opportunities for Metropolitan and our member agencies,” board Chairwoman Gloria Gray said. “Metropolitan is always exploring new, better and more efficient ways to maintain reliability for Southern California, so we are excited to find out just how much potential there is for stormwater capture.”
