Providence County Lake Quality

Rhode Island, 50 lakes, measured by RIDEM

Providence County has 50 monitored lakes, enough that within-county variation matters as much as the county average. Some are deep glacial basins, others are shallow agricultural-watershed waters, and the measurements reflect that mix. The 50 monitored lakes in Providence County carry whatever clarity, phosphorus, and chlorophyll-a readings RIDEM has published, shown as reported.

Most of the county's monitored lakes are shallow, under 50 feet, which means wind keeps the water column mixed all summer and sediment-bound phosphorus releases back into the surface layer whenever the bottom is disturbed.
