Over Night Soaking has Creeks Flowing

Stage II Alarm Drought
Lovelady monitor well: 475.85 ft-msl
Barton Springs discharge: 68 cfs 10-day average

The rain that started yesterday afternoon and fell steadily through much of last night and today has generated substantial runoff and as result, all of the area creeks are flowing. The catchment areas for the creeks responsible for much of the recharge to the Barton Springs Segment of the Aquifer, that is Onion, Bear, Slaughter, Williamson, and Barton creeks, received between about 2 to 3.5 inches over the last 24 hours, and forecasts place the chance of rain tomorrow upwards of 70%. Preceding this rain event, soils already had a high moisture content, thus conditions were prime for generation of runoff. Groundwater levels, for their part, have been on the rise since November and this rain will certainly help continue that trend, possibly even bringing water levels above the drought threshold of 478.4 ft above sea level over the course of the coming days or weeks, but that remains to be seen.
