Overview of Jamaica Bay
 Jamaica Bay is designated for primary contact
and it’s tributaries are designated for secondary
contact
 Water quality in Jamaica Bay is better than its
been in 100 years and supports a wide variety of
wildlife but there are still impairments:
 Waters tend to be eutrophic
 Seasonal low DO levels
 These water quality impairments are linked to
high nutrient loadings in conjunction with man-
made physical alterations
 DEP is upgrading all for of it’s WWTP that
discharge into Jamaica Bay for Step Feed BNR
 Loss of the marsh islands is another critical issue
within Jamaica Bay
 DEP has partnered with ACOE to restore many of
these marsh islands ($13M funded)

Historical Water Quality

4. Additional Water Quality Studies
 In 1995/96 DEP conducted
comprehensive water quality and
ecological studies to calibrate
JEM
 Subsequent comprehensive water
quality, ecological, and finfish
studies were conducted in
2005/2006
 Ongoing Jamaica Bay Science &
Resiliency Institute will be
refining JEM
 DEP to conduct a comprehensive
Post Construction Monitoring
Plan from 2016 thru 2019
