The rainfall that fell across the area late last week helped give a nice boost the Edwards Aquifer, and the city of San Marcos starting tomorrow (Friday, September 21st) will be back in stage 2 water restrictions. The official release is posted at the bottom of the page.
Even though the recent rains have helped the Aquifer, they hardly put a dent in the current drought in our area. Below is the current US Drought Monitor Map for the week ending 9/18/2012 and issued this morning. I have circled in blue areas that have gotten worse in the state in the past week, and it green are the areas that have gotten better. Our area has not seen any change since last week, even with the rains.
Here is the official information from the City of San Marcos.
San Marcos to Return to Stage 2 Drought Rules Friday
San Marcos returns to Stage 2 drought response rules on Friday, Sept. 21, as recent rains helped aquifer levels rise above the trigger levels that have kept much of the Edwards Aquifer region under Stage 3 restrictions since mid-August.
Tom Taggart, Executive Director of Public Services, issued an order on Wednesday to terminate Stage 3 restrictions and return to Stage 2 effective at noon on Friday. San Marcos has been under Stage 3 since August 20 when the aquifer dropped to 637.8 feet and the ten day average declined below 640 feet above mean sea level, the trigger level for Stage 3.
Stage 2 rules in San Marcos restrict use of sprinklers and automatic sprinkler irrigation systems to one day per week on a designated weekday determined by address. Using soaker hoses, drip irrigation and hand watering is allowed on any day before 10 a.m. or after 8 p.m.
The rules also limit at-home car washing to one day per week, prohibit filling new swimming pools, prohibit using outdoor decorative water features, and prohibit washing paved surfaces.
Stage 2 rules are available on the City of San Marcos website at www.sanmarcostx.gov/drought. For more information please contact Jan Klein, Conservation Coordinator, at 512.393.8310. To report watering violations, please call the Water Conservation Hotline at 393.8360.
Stage 2 in the San Antonio Pool of the Edwards Aquifer is implemented when the ten day average at the Bexar County J-17 index well falls below 650 feet or rises above the Stage 3 level of 640 feet above mean sea level (msl). On Wednesday, the 10 day rolling average was at 643.1 feet and the daily reading was 648.0 feet above sea level.
The Edwards Aquifer Authority requires permit holders in the San Antonio pool of the aquifer to reduce pumping by 30% in Stage 2.
In 2011, San Marcos and the Edwards region were under drought restrictions for most of the year through February of 2012.
This year, San Marcos activated Stage 1 watering restrictions on April 23, Stage 2 on May 7, and Stage 3 on August 20 as the aquifer serving more than 2 million people in the San Antonio region experienced a steep decline this summer.
The City of San Marcos receives 85% of its water supply from surface water from Canyon Lake and 15% from the aquifer.
