Dorchester County Lake Quality
Maryland, 1 lake — no lake here has enough monitoring data for a grade
Only 1 lakes in Dorchester County carry an active grade. The county-level summary is therefore representative of those specific lakes, not necessarily of every water body in the county.
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. Transquaking River Higgins Mill Pond (—) is the cleanest in the county.
