Waterbody / Watershed Facts - Paerdegat Basin

BOROUGH:

Brooklyn

SEWER DISTRICTS

Cony Island

COMMUNITY DISTRICT(S):

18

SHORELINE USES:

Commercial; Recreational; Municipal;
Parkland and Open Space

NYSDEC CLASSIFICATION:

Class 1 - Secondary Contact; Fishing

EXISTING WATER QUALITY:

Coliform and dissolved oxygen levels are in non-compliance with standards (Paerdegat Basin CSO Facility Plan, 1991). Dissolved Oxygen levels are at persistent anoxic conditions at the head end. Settleable solids are discharged by CSO; floatables are also discharged but are presently contained by booms. Water quality conditions generally improve in downstream reaches towards Jamaica Bay. The mouth of the basin exhibits episodic conditions of non-compliance.

EXISTING WATER USES:

Recreational Boating and Fishing

SOURCES OF
WATER POLLUTION:

CSO, stormwater and other runoff, impact of Jamaica Bay water quality.

PHYSICAL CONDITIONS
EFFECTING WATER QUALITY
AND USES:

Sediment mound Nuisance odors/discoloration

ECOLOGICAL CLASSIFICATION:

Special Natural Waterfront Area (NYCDCP)

DEP WATER QUALITY IMPROVEMENT PROJECT(S):(WQIP)

Catch Basin Hooding Program; Interum Floatables Containment Program; CSO Facility Plan: Construct tank and inline-storage, Dredging, Remediate adjacent open space conditions.

PROJECTED WQIP WATER QUALITY:

Coliform levels will improve from persistent non-compliance to compliance. Dissolved oxygen levels will improve from persistent anoxic conditions to intermittent summer non-compliance, mostly at head end. Floatables discharges will be virtualy eliminated. Sediment mound and odors will be eliminated.

OTHER WQIP INITIATIVES:

USACE - proposed tidal marsh creation to improve fish and wildlife diversity.
