Grant County Lake Quality

New Mexico, 3 lakes, measured by NMED

Grant County holds 3 monitored lakes. With a sample that small the county-level summary describes those specific waters, not necessarily every water body in the county. The 3 monitored lakes in Grant County carry whatever clarity, phosphorus, and chlorophyll-a readings NMED 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.
