What is the cleanest lake near Dems Lake?

Warg Lake in Hale County reads lower on nutrients and algae and is 18.1 miles from Dems Lake.

What do Dems Lake's readings show?

Dems Lake carries nutrient and algae readings, with about 2.7 ft of water clarity and 24 µg/L of phosphorus. Phosphorus and chlorophyll-a are read against that lake’s EPA ecoregion classes, and clarity is shown separately. The alternatives below read lower on nutrients and algae.

Are these recommendations based on real data?

Yes. Every reading comes from EPA Water Quality Portal samples for the lake. Recommendations are limited to lakes within 30 miles of Dems Lake in Alabama, with strictly higher numeric grade scores and sufficient monitoring data.

Cleaner Lakes Than Dems Lake, Top 1 Within 30 Miles

Reading the cohort

Just one nearby water body scores higher than Dems Lake on the EPA metrics within a 30-mile radius. The single cleaner option (below) is the practical alternative; beyond that, the next-cleanest lakes sit farther out and warrant a longer drive only if the water-quality difference is the deciding factor.

The nearest cleaner alternative — Warg Lake in Hale County — sits 18.1 miles from Dems Lake, putting it firmly in "destination trip" rather than "neighborhood swap" range. The water-quality gap has to be the deciding factor; for a casual outing, Dems Lake is the practical choice and the cleaner options are reserved for purpose-specific visits.

Each lake's nutrient and algae readings — total phosphorus, total nitrogen, chlorophyll-a, and turbidity — are shown beside the EPA National Lakes Assessment 2022 condition class for that lake's own ecoregion, so a reading is compared against the lakes it would naturally resemble. LakeQuality publishes no letter grade. Lower readings mean measurably less nutrient and algae in the water, not better scenery or access: the lake with the clearest, lowest-nutrient water can have worse boat-launch facilities or shoreline access than a neighbor, so the comparison is one input alongside the rest of trip planning. How the readings are classified is on our methodology page.

How this list is built

Sampled lakes on LakeQuality carry readings from EPA Water Quality Portal samples — nutrients and algae measured against EPA National Lakes Assessment ecoregion classes. Secchi is shown, not scored. To suggest cleaner alternatives, we filter lakes within 30 miles to those with a strictly higher numeric score, then rank by the size of the improvement with a small proximity tiebreak. Cross-state and limited-data lakes are excluded so the list stays locally relevant.
