Welcome to Philly Rivercast

January 16, 2022

The Philly RiverCast does not provide water quality ratings during the winter months because data is not available to calculate a RiverCast rating on the Schuylkill River during the winter.

Please visit Philly RiverCast in the spring of 2022 (March 15th), when water quality rating will resume with hourly updates. Thank you!

What is RiverCast?

The Philly Rivercast is a forecast of water quality that predicts potential levels of pathogens in the Schuylkill River between Flat Rock Dam and Fairmount Dam i.e. between Manayunk and Boathouse Row View Map.

The Schuylkill River, like all working rivers, is not a pristine body of water and is subject to contamination from many sources and activities that either discharge directly, or enter the river during rain events. Because rivers are vulnerable to such contamination, Map Image recreation in or upon any body of water has with it an inherent risk of illness and infection for the individual involved.
