Continuous Stream Monitoring Program

The Dauphin County Water Resources Interactive Map has recently been created.  The map allows users to search a municipality or watershed, as well as manually zooming to a location of interest.  Stream classification such as designated use, impaired/non-impaired status, and TMDL information is provided.  
The Dauphin County Conservation District, along with Dauphin County GIS updates the map and its database to improve spatial accuracy and attribute information.  The information contained in this map should not be relied upon by anyone as a determination of water quality or stream designation.  No warranties, expressed or implied, are provided for the positional or thematic accuracy of the data herein, its use, or its interpretation.  Although updates are provided, the information may not reflect the data currently on file in the Dauphin County Water Quality Database.

Note: The GIS interactive map may not display in Microsoft Edge.  If possible use another browser.
