A detailed but accessible summary of Save the Bay‘s assessment of how conditions in Narragansett Bay have improved and declined since the year 2000 is available from the StB website (h/t RightRI)…

This edition shows that, despite considerable progress in some of the indicators, the Bay has declined slightly from an overall score of 4.5 in 2000 to a 4.3 today. The negative trend is driven by sharp declines of fish and shellfish resources, and a spreading area of low dissolved oxygen and unusually warm water temperatures creating a “dead zone” on the bottom.

Though the report labels some of its own recommendations as “strong and even controversial”, its description of fish and shellfish depletion suggest that Narragansett Bay will not fully rebound (especially as a commercial fishing center) in the absence of changes to current environmental management programs.
