Copper River County Lake Quality

Alaska, 141 lakes, measured by Alaska DEC

Copper River County in Alaska carries 141 monitored lakes — one of the lake-richer counties in our dataset. Coverage that dense usually reflects active lake-association sampling alongside state-agency monitoring. The 141 monitored lakes in Copper River County carry whatever clarity, phosphorus, and chlorophyll-a readings Alaska DEC 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.
