Borrego Springs - Groundwater Study


Last updated 11/24/2015 at 2:16pm

A new study completed by the U.S. Geological Survey, in cooperation with the Borrego Water District, will help water planners in the Borrego Valley better understand and manage the groundwater resources that the area relies on for drinking water, agriculture and recreation.

Having collected new data and analyzing decades of historic data, from the Borrego Valley, USGS scientists hope to evaluate the potential hydrologic effects of future development, and quantify the limits of the Valley’s groundwater resources.

The Borrego Valley and the Anza-Borrego Desert State Park, use four times more water than is replenished through annual average natural recharge of the aquifer system underlying the Valley through agricultural irrigation, residential, and commercial users. Groundwater withdrawals have caused groundwater levels to decline more than 100 feet in some parts of the basin.

“Because of this study, for the first time, we have a platform based on hard data that we can use to address sustainability issues in the aquifer,” said Jerry Rolwing, General Manager at the Borrego Water District. “The USGS report pulls together 60 years of data into one authoritative model. For the first time, we now have a numerical hydrologic model we can use to build an action plan as we move into the future.”
