Impervious Surface and Stream Health in Long Island Sound Basins

The indicator tracks the expansion of impervious cover (surfaces such as sidewalks and parkling lots) in the watershed. The impervious cover model predicts expected stream quality of a basin based on watershed impervious cover. View Indicator

Watershed Population

This indicator uses US Census data to track the population living within the Long Island Sound watershed. View Indicator

Population Within 50-mile radius of LIS

This indicator measures the amount of people who live within about a one-hour drive from Long Island Sound who could potentially have an impact on the Sound in their every day activities or through their specific use of the Sound. View Indicator

Open Space

Open Space

This indicator tracks efforts by the state governments of Connecticut and New York to preserve open space through purchases of, or easements on, local properties. View Indicator

Watershed Management

Watershed Management

Watershed restoration strategies are effective ways to support vibrant and healthy aquatic life, and to minimize the negative effects of erosion, sedimentation, and flooding. This map tracks progress by Connecticut and New York towards a goal of having 50 percent of their respective areas in the watershed developing or implementing watershed restoration strategies.
