Sunday, a group of six swimmers ? Maureen Rohrs, Sue Megaw, Jack Frain, Edson Bastos, Richard Wallace and Joe Stewart ? will brave cold water, strong current and exhaustion to swim 4.4 nautical miles on the Patapsco River to raise awareness of the watershed and collect funds for urban watershed organizations.

This will be Stewart?s fifth swim across the Patapsco. To date, he has raised more than $20,000 for urban watershed organizations.
