The City of San Marcos will enter Stage 1 water restrictions April 23 as the Edwards Aquifer continues to decline because of insufficient rain and high demand.

Tom Taggart, executive director of public services for the city, said that even though the winter and spring saw good rainfall totals, it has not been enough to help the Edwards Aquifer recover from nearly two years of extreme drought conditions.

Taggart issued the order to implement Stage 1 restrictions April 18 after the index well in San Antonio reached a daily level of 657.1 feet above sea level, bringing the 10-day average to 659.9 feet above sea level.

The aquifer has recently been dropping at a rate of 1 foot or more per day.

The Edwards Aquifer Authority declared Stage 1 mandatory pumping reductions the same day for the San Antonio pool of the Edwards Aquifer.

The City of San Antonio has already entered Stage 1 restrictions and the Uvalde Pool of the region is in Stage 2.

The Edwards Aquifer, the underground source of water for more than 2 million Central Texans, also produces the San Marcos and Comal Rivers. The region was under drought restrictions for much of 2011, beginning in April and reaching Stage 2 restrictions in the summer.

According to information provided by the city, San Marcos draws about 20 percent of its annual water supply from the Edwards Aquifer and 80 percent from surface water from Canyon Lake.

San Marcos has four stages based on the severity of drought conditions. Residents or business owners who violate the restrictions are subject to criminal penalties ranging from $100 to $2,000 and civil penalties up to $1,000.

Aquifer levels and springflow conditions are published daily on the EAA website, www.edwardsaquifer.org.
