The restrictions limit water use based on specific levels of the Edwards Aquifer.
City Council approved new drought level triggers in 2009.

mean sea level at the monitored well.
Stage 2
Stage Two begins when the Aquifer level reaches 650 feet
mean sea level at the monitored well.

Stage Three begins when the Aquifer level reaches
640 feet mean sea level at the monitored well.
Stage 4
Stage Four restrictions may be declared at the discretion of the City Manager upon completion of a 30-day monitoring period following Stage Three declaration.
