San Marcos will enter Stage 1 drought restrictions effective Tuesday, April 28 at noon in response to the Edwards Aquifer Authority’s declaration of stage restrictions. The EAA entered Stage 1 on April 27 due to low springflows at San Marcos springs.
Both the EAA and City of San Marcos enter Stage 1 when spring flows and/or index well levels fall below designated triggers. The triggers for Stage 1 occur 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 San Marcos springs falls below 96 cubic feet per second (cfs).
On Tuesday, the San Marcos springs were flowing 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.
“We have been monitoring springflows closely over the past few months and have had a few well-timed rains that delayed stage restrictions in spite of the serious drought,” said Tom Taggart, Director of the City of San Marcos Public Services Department. “Unfortunately, recent rains have not significantly affected the recharge zone.”
The city of San Marcos receives 75% of its water supply from Canyon Lake and 25% from the Edwards Aquifer. Under EAA rules, aquifer pumpers are required to reduce water usage by 20% during stage 1 restrictions.
City of San Marcos Stage 1 restrictions include the following:
Monday for addresses ending in 0 or 1.
Tuesday for addresses ending in 2 or 3.
Wednesday for addresses ending in 4 or 5.
Thursday for addresses ending in 6 or 7.
Friday for addresses ending in 8 or 9.
