Today the river flow is down to 89 cfs. The flow is given in cfs - which means cubic feet per second. The average flow of the San Marcos river is about 130 cfs. 100 cfs is pretty low. 500 cfs is very good flow.  We all need to do everything we can to limit our water use, more than we ever have before. Stage 2 restrictions are in affect for San Marcos residents once the flow falls to 80cfs. 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
