District Closes Water Year with 32-Year Recharge Record

San Bernardino Valley Water Conservation District reports stellar year for groundwater storage with 70,000 gallons saved: enough to serve 210,000 families for one year

Local water basins were filled with record-breaking deposits of snowmelt, rainfall and imported water, with 2018-19 Water Year totals achieving numbers not seen since 1987, the San Bernardino Valley Water Conservation District announced today.

Totals for the 2018-19 Water Year, which runs annually from Oct. 1 to Sept. 30, reflect numbers not seen since 1987, with 70,000 acre feet — or 22.8 billion gallons — recharged underground.

Recharge totals reflect the amount of snowmelt, rainfall, and imported water captured by the District into holding ponds, and percolated naturally through silt and sand into the groundwater basin for future use.

SBVWCD General Manager Daniel Cozad attributes the success of this water year to a very wet winter and the establishment in 2018 of a group of local cities and water agencies, known as the Groundwater Council, contributing their fair share of imported State Project water for local storage.

The water stored so far this year is enough to serve 210,000 families for an entire year, Cozad said, but it is being saved to help make up for significant overdrafts in the past.

“Our region is blessed with large underground aquifers that can store significant amounts of water for use in times of severe drought,” Cozad said. “Thanks to our partner agencies on the Groundwater Council, we have been hit by a double-windfall of heavy precipitation and unprecedented collaboration to store as much water as we can.”

The San Bernardino Valley Groundwater Council is a 21st century model for cooperation, where member agencies pitch in their fair share of water for recharge or contribute money for the purchase of imported water to achieve optimum levels of water storage in the San Bernardino and Bunker Hill groundwater basins.

Participation in the council is open to all groundwater producers in the San Bernardino Basin Area. Current members include East Valley Water District; the cities of Colton, Loma Linda and Rialto; San Bernardino Municipal Water Department; Fontana Water Company; San Bernardino Valley Municipal Water District; San Bernardino Valley Water Conservation District, and Yucaipa Valley Water District.

The last time the region stored this much groundwater was in 1987, coming down from a period of successive wet winters. Prior to that spell, 22.8 million gallons of storage wasn’t achieved since the late 1940s.

This year’s record-breaking water storage comes on the heels of two other years of significant recharge.

The 2017-18 water year reflected the highest streamflow recharge levels in five years at 16 billion gallons — the 16th highest recharge amounts since the District started recording measurements 106 years ago.

The 2016-17 water year’s total was 236 percent above average.

Previous years of substantial streamflow recharge include: 2011 (53,986 acre feet); 2010 (30,565 a/f); 2005 (56,980 a/f); 1998 (55,576 a/f); and 1995 (35,876 a/f). The record year for water recharge in the district was in 1922, when 104,545 acre feet of water was captured in retention ponds where it was allowed to seep underground.

Since 1912, the SBVWCD has conserved more than one million acre feet or 326 billion gallons of water by diverting the natural flow of the Santa Ana River and Mill Creek into 71 percolation basins that allow the water to collect and seep naturally into the ground, where it can be pumped out for future use.

Projects

The District is near completion of the Santa Ana River Wash Plan, a Habitat Conservation Plan covering local infrastructure, expanded water conservation and mining and trails in the Santa Ana River Wash.

Conservation

The District has been responsible for Water Conservation for over 100 years. Recharging the groundwater basin in wet times so you have water in dry years.
