2022 Current Water Conditions and 2021 Summary Report Available
2022 Current Conditions
As we close out 2022, water levels in Chester County for the past year have been generally above historic averages. With a week left in the year, the National Weather Service reports that Chester County has already received 51.6 inches of rain, which is 4.5 inches more than the historic average of 47.1 inches. Because we started out the year on the dry side, several groundwater well levels continue to reflect this trend and have generally remained below median levels. Information on 2022 water conditions is presented on CCWRA’s Current Water Levels web page.
2021 Summary Report
The Chester County Water Resources Authority’s 2021 Water Conditions Report is now available online at this link. This 24-page report summarizes select precipitation, streamflow, water chemistry, biological, and water supply data collected in 2021 at monitoring stations throughout Chester County. The data presented in this report provide a snapshot of Chester County’s water resources and highlight long-term water quality trends across the County’s many diverse watersheds.
Chester County Commissioners' Adopt 2022 County-wide Stormwater Management Model Ordinance
The 90-day period for Pennsylvania Department of Environmental Protection (PADEP) to review the final 2022 County-wide Act 167 Stormwater Management Model Ordinance ended on November 24, 2022. Under the Pennsylvania Stormwater Management Act (PA Act 167), all Chester County municipalities, both MS4 and non-MS4 permittees, are required to adopt stormwater ordinances consistent with the County's Model Ordinance by May 31, 2023.
The updated Model Ordinance, summary of changes table, Matrix of Minimum Mandatory Standards, and other resources are available at chesco.org/StormwaterOrdinance. Any questions about the updated Model Ordinance can be submitted to [email protected].
To assist municipalities with updating their stormwater ordinances, CCWRA hosted two implementation workshops in May.
CCWRA provides information on FEMA floodplains as well as real time stream flood monitoring through a partnership with USGS. The Authority also provides flood protection in the Brandywine Creek watershed through the operation of four flood control dams, and has information on preparing for flooding emergencies.
