2002

June

Rainfall during June 30 - July 7 caused widespread flooding and associated property damage across much of the region. The National Weather Service estimated as much as 45-inches of rain fell in portions of the Texas Hill Country northwest of San Antonio. As a result, Canyon Lake in Comal County flowed over the emergency spillway for the first time since construction of the lake in 1968.

August
Stage II water restrictions are declared as aquifer levels decline below 640' msl at the J-17 Index Well in San Antonio. The trigger level for entering stage II restrictions is 640' msl at the J-17 Index Well in San Antonio. Restrictions affect the San Antonio pool, which includes Bexar County and portions of Comal, Hays, Guadalupe and Caldwell counties.

Medina Lake, located in Medina and Bandera counties west and northwest of San Antonio rose to within 18 inches of the top of the dam. The rainfall was also significant in terms of recharge, with aquifer levels rising sharply in response to the rainfall. For example, the Bexar County index well (J-17) level increased a total of 32.2 feet during the month of July.

September
September 8, 2000, the Authority imposes the first-ever region-wide sprinkler restriction because of low flow at Comal Springs. Flow at Comal Springs is reported by the United State's Geological Survey to be 145 cubic feet per second (cfs). The restrictions will affect 1.5 million people living within the jurisdictional boundaries of the Edwards Aquifer Authority.
