The graph shows how imported water allocations from the state vary from year to year and demonstrates the challenges faced by water managers. Cities and water districts have obtained just 5% of their full imported water allotments this year from the State Water Project. And the Colorado River, also a major source of water for Southern California, is headed for a federally declared shortage next year.

As dry, severe drought conditions spread throughout California, Department of Water Resources Director Karla Nemeth said the agency is preparing for what would be its first ever 0% allocation in 2022 because of extraordinarily dry conditions.

The District’s planned or full allocation is 28,800 acre-feet. About 80 percent of the Valley’s water supply is furnished by local groundwater, and the Valley imports about 20 percent of the water we use from northern California and the Colorado River. A 60 percent allocation is needed to meet the demand of our member cities for replacement water. Thus, in years where the allocation dips below that amount, we see the important role that water storage plays.

SGVMWD Operations and Local Water Delivery Update

In May, the District completed delivery of all 1,440 acre-feet (5%) of its allotted 28,800 acre-feet of imported water to the San Gabriel Canyon spreading grounds which is used to replenish declining groundwater supplies in the Main San Gabriel Basin. The District has continued ongoing maintenance and repairs to equipment, computer systems and pipeline/water delivery infrastructure. 

In addition, the District has begun long-range infrastructure planning which includes development of a conditions assessment which will lead to an asset management and financing plan.

Update: SGVMWD Infrastructure Loans to Member Cities

Last month, we introduced our new water supply “dashboard” (see illustration) which provides monthly water supply data “at-a-glance” for the San Gabriel Valley and the State. Water supplies in the San Gabriel Valley (local groundwater) and statewide remain below normal and average as shown by the bleak pictures of the local, San Gabriel Reservoir in the nearby San Gabriel Mountains (below left), and the State’s second largest reservoir, Lake Oroville, which is less than 50% full (below right). 

The past two years have been the driest in nearly half a century, with drought creating conditions comparable to the severe drought of 1976-77. The snowpack this year in the northern Sierra Nevada, which feeds the state’s reservoirs, peaked at 72% of average in April, and then rapidly melted during the hottest spring on record. 

Warming temperatures are a major contributor to worsening drought conditions as temperatures are about two degrees hotter, on average, now than 50 years ago. This results in greater evaporation during precipitation events, less melting snow feeding rivers and reservoirs, and soil moisture drying out before soaking down into the ground. 

Computer models show that in the future, dry years will be drier, and wet years will be wetter.

Local Groundwater – in the Main San Gabriel Basin, the “Baldwin Park Key Well” is the indicator of groundwater levels (see graph – blue line includes cyclic storage; black line does not). As of October 1, 2021, the level is 184.8 feet above mean sea level. The Basin has experienced a fairly steady decline from 212.5 feet above mean sea level in December 2019. The present level is still an improvement from the historic low of 169.4 as recently as November 21, 2018. Watermaster’s operating guidelines for replacement water or “safe yield” is between 200 and 250 feet above mean sea level. Main San Gabriel Basin groundwater supplies, which account for nearly 80% of the water we use, remain below desired levels and remain in need of ongoing smart management, replenishment and conservation.

Local Rainfall – the Los Angeles Almanac reports annual rainfall levels from July 1 of each year to June 30 of each year. At the Santa Fe Dam weather station, .36 inches of rain have fallen year to date; .34 inches are normal but the total represents only 2.1% of the full year norm. Rainfall totals for the year ended June 30, 2021 were 6.49 inches compared to a season normal of 17.38 inches (37% of normal).

Statewide Snow Pack – as of October 1, 2021, statewide, the average “snow water equivalent” is 0.1 inches. Snow levels are 0% of normal for this date and 0% of the April 1 average. On average, the Sierra Nevada Mountains snow pack, which is a key source of water banked in reservoirs, supplies about 30% of California’s water needs as it melts in the spring and early summer, feeding reservoirs and the water table, resulting in groundwater.

Statewide Reservoir Levels – statewide, as of August 31, 2021, (the latest data available to us), reservoir levels were at 60% of average and 36% of capacity. Every winter, most areas need about 12 inches of rainfall before the ground is saturated enough to get large amounts of runoff into streams and reservoirs. Because last year’s precipitation levels were low and the ground was so dry, the ground absorbed high levels of recent precipitation. California’s reservoirs generally hold enough water to go one dry year without impacts but begin to empty if a wet year does not follow.

The District Teams Up with Member Cities to Promote Water Conservation

The District’s water conservation and education campaign theme for 2022 is a simple and fun call to action: “Saving Water…it’s a good thing!” The message can be taken two ways: that water, itself, is a good thing; and that the act of saving water is a good thing. Regardless of your interpretation, we hope the positive theme/message for 2021 is inspiring and helpful.

As pictured, our member cities are getting the word out in the form of banners, bus shelters and lobby signs, with much more drought outreach planned. We will provide updates in future issues of the newsletter.

Fall Water-Saving is Crucial to Preserve Local Groundwater Supplies!

As weather remains warm and dry into the Fall, water use remains high throughout the San Gabriel Valley, so it is an important time to save water and save money.

Shown below are water saving tips formulated for the Fall months that will also save you money. Items such as water-efficient appliances, irrigation controllers, rotating sprinkler nozzles and rain barrels are eligible for the District’s rebate program .

The District created several new educational videos (insert link), and a new, fun “Water Awareness Growth Chart.” The chart will help students learn more about groundwater, imported water, water terminology, and water conservation. The fun part is the Growth Chart is about 3-feet long and folds out so that students can keep it long-term. Please download the Growth Chart from our website or contact us (626-969-7911 or info@sgvmwd.com) and we will send to you.

With the easing of pandemic-related restrictions, the District is again supporting and participating, with the utmost care and safety, in some community events in-person as the year progresses. We will also be seeking to provide in-person presentations and workshops about water supply and water conservation. We are always open to providing virtual or on-line presentations, as well.

One of the first “live” events to occur this summer was “National Night Out” in Alhambra, where the District supported the public safety event with a booth and water conservation and education materials. We look forward to seeing you in person, to introducing you to H₂Owl and talking more about water issues! Please let us know about speaking opportunities and other events we might support with water education materials and our kid-friendly mascot. Please contact Evelyn Reyes at either

626-969-7911 or ereyes@sgvmwd.com. 

The Opportunities for Water Leadership Grants (O.W.L.) are available! The Grant Program is a great way to aid educational events such as Earth Day festivals (outdoors or virtual/on-line), re-landscaping projects, waterway cleanups, tree plantings, school projects, conservation curriculum, and other civic, volunteer activities. 

The grants range from $200-$2,000 for local, creative water conservation projects. The District welcomes creative ideas from schools and non-profit organizations. We are happy to provide technical assistance to help you complete the grant application.

A recap of our grant recipients to date is shown below and included on the District’s website: Please click here to read about the Grant Program and to access the online application. For further information, please contact the District at 626-969-7911.

The San Gabriel Valley Municipal Water District has offered a rebate program for many years for a variety of water-saving appliances and equipment. Many residents have cashed in and reaped the benefits of lower water bills and money in their pockets.
