The City of San Marcos entered Stage 1 drought restrictions Tuesday at noon.
This action results from the Edwards Aquifer Authority’s (EAA) decleration of stage restrictions. The EAA entered Stage 1 on April 27, due to low spring flows at the San Marcos Springs.
“We have been monitoring spring flows closely over the past few months,” said San Marcos Public Services Department Director Tom Taggart, “and have had a few well-timed rains that delayed stage restrictions in spite of the serious drought.”
Taggart continued, “Unfortunately, recent rains have not significantly affected the recharge zone.”
A Stage 1 restriction happens when spring flows and/or index well levels fall below designated triggers. The trigger for Stage 1 occurs when the ten day average J17 index well level falls below 660 feet above mean sea level, or when the ten day average flow rate at the San Marcos Springs falls below 96 cubic feet per second (cfs).
On April 27, the San Marcos Springs flowed at 94 cfs, with a ten-day average of 94.1 cfs. Last year at this time, the springs were running at 154 cfs. The historical average for April is 176 cfs.
Stage 1 restrictions include the following:
- Waste of water is prohibited.
- Irrigation with sprinklers and automatic sprinkler systems is allowed only one day per week on the designated weekday, between the hours of midnight to 8 a.m., and 8 p.m. to midnight.
