Henry County Lake Quality

Henry 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 an A–F grade, so the county-level summary covers the full set rather than a monitored subset. On average, Henry County lakes grade D, with phosphorus loading and reduced clarity showing up across most of the dataset.

The county's lakes lean shallow, which makes the grades sensitive to wind, sediment-resuspension, and any nutrient inputs from the watershed. The cleanest lake on the books is Lake Jericho (D); the most-stressed is Lake Jericho (D).
