Cass County Lake Quality
North Dakota, 2 lakes, measured by ND DEQ
Cass County holds 2 monitored lakes. With a sample that small the county-level summary describes those specific waters, not necessarily every water body in the county. The 2 monitored lakes in Cass County carry whatever clarity, phosphorus, and chlorophyll-a readings ND DEQ 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.
