Helping Make Every Day "Earth Day" in Our Member Cities!

City of Monterey Park's Earth Day festival in conjunction with their annual Cherry Blossom Festival on Saturday, April 15 at Barnes Park.

In the City of Sierra Madre, Director Miles Prince joined the community in unveiling their new native garden at their local United States Post Office on Saturday, April 22. The District was a proud sponsor and supporter of the project that was all built by volunteers. Their annual Earth Day Festival capped off the day at Memorial Park.

City of Alhambra hosted their annual Eco-Fair in conjunction with the Farmer's Market. Alhambra High School's ERAS (Environmental Resources Awareness Society) partnered with us to pass out giveaways and educate the community on ways to conserve water at home.

City of Alhambra Mayor Adele Andrade-Stadler and SGVMWD Director Mike Eng stopped by for the festivities.

Department of Water Resources Increases State Water Project Supplies to State Water Contractors to 100% for 2023

As seasonal precipitation begins to taper, what will be an incredible snow melt has begun, further improving water supplies. As a result, the District is very pleased with the state’s announcement on April 20, 2023 to increase State Water Project (SWP) allocations to state water contractors, such as SGVMWD, to 100% of plan, which last occurred in 2006, after continued rain, snow and runoff following recent storms. The increase means the District will receive 28,800 acre-feet of imported water to use for replenishment of groundwater in the Main San Gabriel Basin.

Imported water supplements local groundwater supplies in the Main San Gabriel Basin and Raymond Basin, the primary sources of water for the District’s member cities of Alhambra, Azusa, Monterey Park, and Sierra Madre. The planned allocation may be adjusted in the future based on hydrological conditions.

SGVMWD's Member City Water Rate Update

The San Gabriel Valley Municipal Water District remains focused on fiscal responsibility and developing a sustainable water supply for our member cities. We are pleased that the wholesale water rates we charge to our member cities for replacement water remain, by far, the lowest in the Main San Gabriel Basin. In addition, the District's property tax rate, which is used to fund the fixed costs of the State Water Project, has been unchanged since 2017, at .030 cents per thousand dollars assessed value. Prior to 2017, that rate had been unchanged for 30 years.

In the past few years, the District invested in several supply sustainability and water quality initiatives benefiting our member cities short and long-term: more than $8 million in water infrastructure and supply projects in our member cities and $2.8 million in the Department of Water Resources (State Water Project) Delta Conveyance Project. We also formalized support of the Pure Water Southern California recycled water project and enhanced maintenance of our facilities. During the drought we implemented a broad-based water conservation and education program; increased funding for our rebate, direct install irrigation and community grant programs; and continued our thought leadership by sponsoring Asian media and Earth Day events, local Town Halls, and the San Gabriel Valley Water Forum.

We have experienced increasing “fixed” costs for participation in the State Water Project, from an average of $5.4 million per year from 2010-2014, to $6.8 million in 2015, to $7.5 million in 2022. In addition, we have also experienced large cost increases to maintain our own infrastructure as our pipeline approaches 50 years in operation. We've been able to mitigate these effects to a degree by obtaining additional sources of revenue such as grant funding and reducing discretionary expenses. 

At its April 10, 2023, meeting, the Board of Directors voted unanimously to set the water rate at $220 per acre-foot for 2023, and to advise our member cities that we anticipate the rate increasing to $240 per acre-foot in 2024, based upon the latest forecast provided by the Department of Water Resources. In 2015, for the first time since 1989, the District adjusted its water rate from $130 per acre-foot (AF) to $145 per AF to compensate for the sharply rising State Water Project costs. We completed a three­ year rate adjustment that moved our rate to $200/AF by 2018-2019 and that rate was unchanged through 2022. These rates remain extremely fair and competitive: other importing water agencies in the San Gabriel Valley now have rates more than $1,000/AF for groundwater replenishment.

The rate is a pass through of the State Water Project variable cost which is the amount the Department of Water Resources charges each State Water Contractor (e.g. SGVMWD). The District has historically tried to match this cost with its replacement water rate. The District has never profited from water sales to its member cities.

Operations Update

In April, the District delivered 194 acre-feet of imported water to local spreading grounds to supplement cyclic storage supplies in the Main San Gabriel Basin. In addition, the District delivered 476 acre-feet of water to Covina Irrigating Company on behalf of Three Valleys Municipal Water District. The District began water deliveries on April 26. With the Department of Water Resources increasing the allocations to State Water Contractors such as SGVMWD to 100%, the District will be working hard to receive and deliver as much imported water as possible to the Main San Gabriel Basin.

The start of the snow melt and ensuing water runoff in April further improved drought and water supply conditions statewide and in the San Gabriel Valley. The graphics above show the marked improvement from January through May 2023 in state and local reservoir, snowpack and groundwater conditions. They also show significant change in the severity of drought statewide. As many reservoirs are approaching capacity, snowpack is more than double normal levels, and local groundwater, which improves more slowly due to the time it takes stormwater runoff to percolate down to groundwater levels, has risen more than 30 feet year-to-date. 

While the most recent drought is effectively over, we must remember we live in a region where most years are dry, where drought will return and where climate change makes the work of water planning and delivery challenging. The reality remains that if we’re not in a drought, we are probably either getting into one or recovering from one. 

We need to sustain our focus on developing a long-term water conservation ethic that enables us to save water now, when it’s wet, for when it’s dry. While the State has lifted many water use restrictions, it’s important to note that in the past 1-2 years Californians fell short of meeting the voluntary 15% conservation goal and were only saving water at a 6% rate, far short of the 25% conservation level achieved in the next most recent drought period. 

Groundwater – in the Main San Gabriel Basin, the “Baldwin Park Key Well” is the indicator of local groundwater levels (see graph – blue line includes cyclic storage; black line does not). As of April 27, 2023, the level increased significantly to 224.1 feet above mean sea level, compared to 204.9 in early April, 189.7 feet in March, 179.4 feet in February and 179.2 feet in January. Prior to the storms earlier this year, the Basin had experienced a steady decline in groundwater levels from a high of 212.5 feet above mean sea level in December 2019 and was trending downward toward the historic low of 169.4 recorded on November 21, 2018. One vertical foot is equivalent to about 8,000 acre-feet of groundwater in the Main Basin. Watermaster’s operating guidelines for replacement water or “safe yield” is between 200 and 250 feet above mean sea level. 

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 and water conservation play.

Note: Groundwater use accounts for 41% of California’s total water supply (80% in the San Gabriel Valley) on an average, annual basis, and as much as 58% in a critically dry year. About 85% of public water systems rely on groundwater as their primary supply. Of water diverted and pumped in California, about 80% is used by agriculture and 20% is used by cities and towns.

Imported Water – In April, the California Department of Water Resources increased State Water Project allocations to State Water Contractors such as SGVMWD for 2023 to 100% for the first time since 2006. Imported water is used to supplement local groundwater supplies in the Main San Gabriel Basin.

Note: Two-thirds of California’s water originates in the Sierra Nevada Mountains and flows through the Delta, a large inland river delta and estuary in northern California.

Statewide Snow Pack – as of April 27, the snow water equivalent was 53.8 inches, which is 211% of April 1 average and 258% of normal for this date (snowpack is measured from April 1 to March 31, a 12-month period). April 1 is usually the “high point” for snow accumulation each year. The current snowpack is one of the biggest the state has experienced since the 1950s.

Note: On average, the Sierra Nevada Mountains snowpack, 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. The snowpack is often referred to as California’s “frozen reservoir.”

Statewide Reservoir Levels – statewide, as of March 31, 2023, (the latest statewide data available to us), reservoir levels had risen to 105% of average and 72% of capacity, with further gains imminent in April and May as the snowmelt and runoff occurs. As of late April, storage levels at Shasta Lake, the state’s largest reservoir, were 96% of capacity and 115% of the historical average for this date, and storage levels at Lake Oroville, the state’s second largest reservoir, were 90% of capacity and 118% of the historical average. 

Locally, both San Gabriel Reservoir and Cogswell Reservoir are presently more than 125% of average. During the recent drought, low precipitation levels, high temperatures, hot and dry soil, and high levels of evaporation decreased stormwater runoff from surface levels to replenish both reservoirs and local groundwater supplies.

Note: 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. 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’s popular and long-running Opportunities for Water Leadership Community Grant Program (O.W.L. Grants) provided grants ranging from $500-$1,500 to schools and non-profits for Earth Day related educational activities in April. These grants were IN ADDITION to the ongoing unlimited grant program. If you were unable to participate in the Earth Day grant program, please consider our ongoing grant program.

Streamlined applications and additional information about the program are posted on the District’s website (https://sgvmwd.com/water-conservation/#owl-grants). Our intent was to use the “seed” grants to spur new “Earth Day” environmental and water education activities and to build new, long-term partnerships at schools and non-profit organizations on Earth Day and beyond.

The District’s O.W.L. Grants Program was featured in September 2022 by ABC-Channel 7 to help encourage water conservation as part of its “Water-Wise Wednesday” community feature. The entire news segment may be viewed with the link below.
