The San Marcos Springs flow relies on Water Conservation
The average flow of the San Marcos river is about 130 cfs. The flow is given in cfs - which means cubic feet per second. 100 cfs is pretty low. 500 cfs is very good flow. Texas is known for periods of drought followed by flooding. The Edwards Aquifer is a limited resource which over 2 million people rely on for their drinking, municipal, agircultural and industrial needs.To review the rules about drought restrictions see this link from the city of San Marcos: http://ci.san-marcos.tx.us/departments/WWW/Docs/09apr_DroughtResponseRulesBrochure.pdf
