GOWANUS CANAL Borough(s): Sewer District(s): Community District(s): Shoreline Uses:
Brooklyn Owls Head and Red Hook 6 and 7 Commercial Municipal Industrial Parkland and open space
NYSDEC Classification:
Class SD - Fishing
Existing Water Quality:
Dissolved oxygen levels are in non-compliance with standards (Inner Harbor CSO Facility Plan, 1991). However, when the DEP Flushing Tunnel is operating, dissolved oxygen is improved to general compliance throughout the canal with minor periods of noncompliance in lower reaches towards Gowanus Bay. There are no coliform standards for SD waters. Settleable solids are discharged by CSOs. Floatables are also discharged by CSOs but are substantially contained by a boom.
Existing Water Uses:
Commercial shipping and barging, recreational boating
Source(s) of Water Pollution:
CSOs, storm water and other runoff
Physical Conditions Affecting Water Quality and Uses:
Dredged Sediment deposition Nuisance odors/discoloration Floatables
Ecological Classification:
No designation
DEP Water Quality Improvement Project(s): Catch Basin Hooding Program (WQIP) Interim Floatables Containment Program CSO Facility Plan - reactivation of Flushing Tunnel (180-300 MGD, averaging 200 MGD) - ongoing planning Projected WQIP Water Quality:
General compliance with dissolved oxygen standards when Flushing Tunnel is operating. Floatable discharges are substantially contained.
Other WQIP Initiatives:
None
