Mellette County Lake Quality
South Dakota, 1 lake, measured by SD DANR
Mellette County holds 1 monitored lake. With a sample that small the county-level summary describes those specific waters, not necessarily every water body in the county. The 1 monitored lake in Mellette County carries whatever clarity, phosphorus, and chlorophyll-a readings SD DANR 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.
