Jacob’s Well stops flowing due to drought, increased pumping

Jacob’s Well Natural Area announced on Wednesday that zero flow had been recorded at the natural springs.

The data comes from the U.S. Geologic Survey, which showed that zero cubic feet per second was reported intermittently over the past few days.

A look back at historical data revealed that Jacob’s Well has stopped flowing only four times before — the summers of 2009, 2011, and 2013. It also came perilously close to zero flow in September 2014. All happened during times of drought for South and Central Texas.

The Facebook post from Jacob’s Well State Natural area described the situation as a “cause for concern and is the result of ongoing drought and increased levels of groundwater pumping.”

Drought conditions continue to worsen, with 2022 resulting in one of the driest starts to a year in history for San Antonio. Many parts of the area are experiencing exceptional drought.

Jacob’s Well, which is about an hour north of San Antonio, has long been a popular swimming spot known for its beauty. The well is an artisan spring that, in good years, will release thousands of gallons of water a day from the Trinity Aquifer. It’s also the second largest fully submerged cave in Texas.

Jacob’s Well is the headwaters of Cypress Creek, which flows through Blue Hole Regional Park and feeds into the Blanco River.

Reservations are needed to use the waters at Jacob’s Well. However, that was discontinued earlier this month due to low flow.
