Project Clean Stream

Project Clean Stream (PCS) started as a local stream cleanup that took place just one day out of the year. Since 2002, the Alliance for the Chesapeake Bay has taken this model for local volunteer engagement and grown it into an annual watershed-wide season of service. Every spring and fall, tens of thousands of volunteers come together to pick up trash from local streams, creeks, rivers, parks, and neighborhoods as part of the Alliance Project Clean Stream — the largest cleanup event in the Chesapeake Bay region! 

For more information about Project Clean Stream, please visit our website here.

The spring Project Clean Stream season will kick off on Friday, April 4, 2025.
