The Illinois State Water Survey (ISWS), under contract to the Northern Logan County Water Authority, continuously monitors 5 wells, SWS-E, SWS-10, SWS-08, MTH-22D, and MTH-22S. Two water levels are monitored at MTH-22, deep (labeled D) and shallow (labeled S). These four wells are part of the larger McTaz monitoring network, shown in the map. 

 

 

*This network is funded by the Northern Logan County Water Authority.
