Montgomery County Lake Quality

Pennsylvania, 2 lakes, measured by PA DEP

Montgomery 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. Every one of those lakes carries recent nutrient and algae readings, so the county-level summary covers the full set rather than a monitored subset. Phosphorus and algae readings vary widely across Montgomery County; the per-lake pages below carry the numbers.

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. Green Lane Reservoir has the lowest nutrient and algae readings in the county.
