This is DRAFT visual and map material to give members of the Community Advisory Group and other interested parties an introduction to New York City’s Water Quality Rating Classification System and what could be done about reducing sewage to the Canal. Prepared as a discussion resource by members of the CAG Water Quality Committee, and will be replaced.An urban legend has it that the term “Gowanus Canal Paddle” was a swim stroke perfected by local teenagers in the 1970’s, where your arm stroke moves “floatables” out of the way. Correction: Note a mistake in the text - CSO RH 35 is sewer overflow being fixed by DEP not CSO RH 34. The City is proposing to INCREASE sewer overflows at RH34 by 5%.
