Welcome Soaking over the Weekend

Stage II Critical Drought
Lovelady: 466.68 ft-msl
Barton Springs: approximately 35 cfs 10-day average

The rain over the weekend was substantial enough to create flow in area creeks where the majority of recharge to the Barton Springs Segment of the Edwards Aquifer occurs. Hopefully these rains are the precursor to the wet conditions possible with the arrival of El NiƱo conditions which the National Weather Service places a 58% chance of developing during winter 2014-2015 and lasting into spring 2015. Although Barton Springs experienced a sudden increase in flow due to the rain over the weekend, that increase does not indicate an increase in groundwater storage in the aquifer, rather a sudden surge of surface water travelling quickly through developed karst conduits (caves, sinkholes, etc). Lovelady monitor well hydrograph, the District's other drought trigger site, has slowed its descent into deeper stages of drought for the time being and may be indicating a subtle rise in aquifer water levels due to the rain, but whether that is the case or not remains to be seen.
