During the summer, a team of students and scientists led by Chris Gobler, professor of marine science at Stony Brook University and director of the New York State Center for Clean Water Technology, tests the water quality weekly at 30 locations around Long Island. The result is the Long Island Water Quality Report, which aims to provide regular snapshots of ecosystem health, with an eye to how well the region's bays, harbors, rivers and inlets support robust fishing and shellfishing activity.

A good rating indicates clear water, adequate oxygen levels and no or low levels of algae or bacteria from human or animal waste, with levels of all parameters meeting or exceeding all state and federal water quality standards.

This week’s ratings are as follows:
