Department of Water Resources' (DWR) Analysis Concludes Benefits of Delta Conveyance Project Far Exceed Costs

A benefits-cost analysis of the Delta Conveyance Project by the DWR indicates the infrastructure modernization project would create billions of dollars in benefits for California communities (more than double the costs), including reliable water supplies, climate change adaptation, earthquake preparedness and improved water quality. A key finding is the Project will deliver nearly $38 billion in benefits, preventing both water shortages and water rationing, and saving more water during wet years. 


This new benefit-cost analysis provides a financial rationale for the public water agencies funding the project, such as the San Gabriel Valley Municipal Water District, to be able to continue to provide an affordable, safe, clean and reliable water supply. For more information and to read the full study, follow the link below to the DWR website.

Operations Update

 

Imported Water Deliveries


In June 2024, the District delivered 2,314 AF of imported water to cyclic storage through its San Dimas hydroelectric power plant and Azusa Flow Control Structure. 343.9 MWh of power was generated for Azusa Light and Water. With Schedule I back in service, 827 AF of water was delivered to Covina Irrigation Company on behalf of Three Valleys Municipal Water District.


Standby Generator Replacement Project


A Request for Proposals has been sent out to replace five (5) standby generators and one (1) new installation at six District facilities.


State Water Project Update


On April 23, 2024, following an above average rain and snow “season” in California, the Department of Water Resources increased its allocation of imported water to State Water Contractors from 30% to 40% of contracted supplies (11,520 AF for the SGVMWD). The state may increase or decrease the allocation amount as the year proceeds based on hydrological conditions.

In 2023, the District was allocated 28,800 acre-feet, or 100%, of its imported water allocation to deliver for replenishment of groundwater in the Main San Gabriel Basin. Some of the District’s allocation for 2023 was carried over into 2024 as capacity to deliver and store water in the Basin was limited late in 2023 due to high volumes of water in the system.


We are working closely with state and county water agencies to utilize available capacity in reservoirs, pipelines and spreading grounds to deliver the imported water. With water delivery capacity at times challenged by the abundance of stormwater runoff and snow melt throughout the state, scheduling deliveries is complicated and requires collaboration and smart water management with other water agencies 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.

WATER SUPPLY CONDITIONS

Drought is Non-Existent and State and Local Water Supply Conditions Hold Steady as Hot Summer Months Arrive


June 2024 dashboard

After a wet winter and spring, drought is non-existent in California and water supply conditions are both much improved and holding steady, very positive developments for the Main San Gabriel Basin and California. It’s been an above average water year but will fall short of last year when we experienced the 10th wettest year since record keeping began 128 years ago.


One of the most important indicators for the San Gabriel Valley is local groundwater which improves more slowly due to the time it takes stormwater runoff to percolate down to groundwater levels. Our local groundwater levels have risen almost about 60 feet since January 2023.


In 2023, the Main San Gabriel Basin captured more than 95% of stormwater to supplement local groundwater supplies, which is much different than other watersheds that convey much of their stormwater to the Pacific Ocean as a flood control measure. Data from Watermaster reveal that of the more than 500,000 acre-feet of stormwater captured this year, about 300,000 AF came from the San Gabriel River watershed.


We must remember we live in a region where most years are dry, we use more water than Mother Nature provides, infrastructure is aging, drought will return, and climate change makes the work of water planning and delivery challenging. We need to sustain our focus on investments in long-term water infrastructure and developing a long-term water conservation ethic. 


Groundwater in the Main San Gabriel Basin, the “Baldwin Park Key Well” is the indicator of local groundwater levels (see graph below – blue line includes cyclic storage; black line does not). As of June 30, 2024, the level stood at 239.5 feet above mean sea level, as stormwater runoff slowly percolates down to groundwater levels where it is pumped for use in the San Gabriel Valley.


Prior to heavy precipitation and storms in early 2023, 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.


Note: 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. 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 – As presented earlier, in April, the state increased allocations of imported water to State Water Contractors to 40% of requested supplies for 2024. Changes in the allocation level may still occur in 2024 based on evolving hydrological conditions. Imported water is used to supplement local groundwater supplies in the Main San Gabriel Basin.


In April 2023, 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. Those deliveries have been maximized as much as the delivery and storage “system” can handle, and some of the District’s 2023 allocation was carried over into 2024.


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.

Local Rainfall the LA County Department of Public Works (DPW) reports annual rainfall levels from October 1 to September 30 of each year. As of June 30, 2024, the DPW headquarters location in Alhambra had recorded 23.23 inches of rain since October 1, 2023, when our new “water year” began, about 130% of average (average is 17.83 inches of rain), concluding an above average rain year, but falling short of the last “water year” total of nearly 40 inches of precipitation. The graph below shows both annual rainfall totals dating back to 1960, as well as the major drought cycles (shaded in brown) since then.

Statewide Snow Pack – As of June 30, the snowpack is 1% of the April 1 peak which is about 9% of normal. 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 snowpack is expected to melt off earlier than last year, when an enormous snow accumulation lingered into August, keeZping high elevations moist through the summer. The mountains are also running drier this year compared to the coasts, which bore the brunt of El Niño-fueled storms this past winter.


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 and Local Reservoir Levels – Statewide, as of May 31, 2024, (the latest statewide data available to us), reservoir levels were 118% of average and 89% of capacity, mostly unchanged from last month. Most reservoirs in the state are above average. As of June 30, storage levels at Shasta Lake, the state’s largest reservoir, were reported at 90% of capacity and 114% of the historical average for this date, and storage levels at Lake Oroville, the state’s second largest reservoir, were at 97% of capacity and 126% of the historical average. Lake Silverwood, which is located above San Bernardino and is adjacent to the start of the District’s Devil Canyon-Azusa Pipeline, is filled to about 89% of capacity and 118% of average.


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.
