Edwards & Trinity Water Levels Declining

Lovelady well height: 542.87 ft-msl (110.55 ft-Depth to Water)
Barton Springs: approximately 109 cfs 10-day average

Central Texas enters August with none of the area in drought conditions. This is directly the result of the wet winter and spring of 2015-2016 leading to some near-historic rainfall totals and high surface-water and groundwater levels. Groundwater levels in the Edwards and Trinity Aquifers reached their peak elevations in mid-June, and are now declining with the lack of rain in much of central Texas. The figure illustrates the rise and fall of aquifer levels in three wells in central Hays County for 2016.

As we enter a typical dry and hot Texas summer we are seeing the natural hydrologic response to those changing conditions--dropping water levels. The outlook from the Climate Prediction Center for the next few weeks calls for above-average temperatures and lower than average chances of rainfall. We are fortunate to have the high water-level conditions as we may enter La NiƱa conditions this fall and winter, which can result in drier than normal conditions.
