Recent rainfall results in big change in our drought status


SAN ANTONIO - Just a month ago the Edwards Aquifer was sitting at 661 feet. That's just one foot above Stage 1 water restrictions. Now after the 4-6 inches of rainfall we received on the 28th of March across San Antonio and nearby counties, we are almost eight feet above those restrictions.

But even better news is what the heavy rainfall did for our drought status. Going into March we were looking at a rainfall deficit of over 1 1/2" below our normal rainfall in San Antonio, and even more of a deficit in parts of the Hill Country and around Medina county. This put the western part of Bexar County in a "Severe" drought status, and the rest of the county in a "Abnormally Dry" area.

Now fast forward to today and the map shows the majority of Bexar County only in the 'Abnormally Dry' area and the southwest part of the county and parts of Medina, Frio and Atascosa in a "Normal" rainfall area. That means we are now getting the average rainfall we should be getting.

Areas that remain under "Severe" drought are from Uvalde to Del Rio South to Eagle Pass.

The takeaway from this change is that one large area of thunderstorms can dump inches of rainfall and turn around our drought fortunes quickly. But it also is a reminder that a month or so without any major rainfall can put us in peril fairly quickly, especially if lack of rainfall happens during one of our normally wet months like April, May or June.
