What's New

  • Interactive Online Water Resources Mapping Tools Available  NEW 
    • CCWRA created online map products to assist residents, municipalities, businesses, and visitors by providing a "self-serve" way to view maps of the water resources of Chester County. These maps are interactive and do not require special software or plugins. Information provided includes whether streams are polluted/impaired, if there are regulatory mandates for water quality improvements (TMDLs) and other information related to stream health.

  • Volunteer Opportunity: Participate in the Volunteer Rainfall Observer Network
    • We are seeking volunteers to participate in the Chester County Volunteer Rainfall Observer Network.  Volunteers are responsible for taking readings of a rain gage daily and after significant precipitation events, manually recording the readings, and submitting the log on a monthly basis by e-mail or postal mail.  CCWRA compiles the data for analysis, and the updated results are posted on the CCWRA website.  A 3-inch diameter plastic rain gage is provided at no cost to the volunteers.  The volunteer is responsible for mounting the rain gage to a post or other suitable location at their home.  An ideal volunteer is committed to recording --- on a daily basis --- consistent and accurate measurements, and willing to participate as a volunteer for years.  If you are interested in finding out more about the Network or to become a volunteer, please contact the CCWRA at 610-344-5400.
