About The Protection Committee

In recognition of their shared interests and an understanding that water quality and coastal issues are best addressed on a coordinated, watershed level, in 1998 North Hempstead, Nassau County, and eleven Bay coastal communities voluntarily entered into an inter-municipal agreement for water quality planning purposes. 

In spring of 1999, the Manhasset Bay Water Quality Improvement Plan was completed. The Plan identified bacteria-pathogens, sediment, nutrients, and litter/debris as the major non-point source pollutants affecting Manhasset Bay and storm-water run-off as the major conduit. Implementation of the Plan began in 1999 with funding through the Environmental Protection Fund. 

There are fifteen (15) member municipalities: 13 villages, the Town, and the County. A representative from each member-municipality is appointed to serve on the Committee. The job of each representative is to: represent the needs of its municipality, present ideas for Committee activities, serve as an advisor to the Director of the Committee, and, most importantly, bring tools and information back to its municipality so that it can become an effective part of the effort to restore and protect Manhasset Bay and its watershed.

If you would like to volunteer to represent your Village, please e-mail the Director ( for help in getting in touch with your Village administration.

  1. A tool to educate residents that live within the watershed of the 14 municipalities in order to improve water quality in the Bay.
  2. To educate residents on the affects of storm water and failing septic systems have on the Bay.
  3. A storehouse of educational articles, pamphlets, posters and fact sheets to review.
  4. List local events that concern the Bay.
  5. Get comments on how to improve the web site.



We want to hear from you!
