Steady Decrease in Lovelady

Drought Status: Stage II Alarm Drought
Barton Springs: 22.2 cfs*
Lovelady Well: 463.8 ft-msl

*Construction at Barton Springs pool is causing unreliable discharge measurements

The date in early March on which the Stage III Critical Drought threshold was expected to be crossed has been moved to later in March after a better fit was made between the Lovelady monitor well hydrograph and the recession curve during the 2011 drought (see graph below). Construction continues at the Barton Springs pool making accurate flow measurements difficult to obtain. Due to the uncertainty of flow at Barton Springs, the District is relying more heavily on the water level in the Lovelady monitor well to determine the stage of drought. The current water level in the well is just over foot above the elevation marking the onset of a Stage III Critical Drought. Water level in the well is steadily dropping and will likely cross into Stage III drought before the end of the month.
