Lake Hartwell's algal bloom toxins are decreasing

Harmful algal bloom toxin levels in Lake Hartwell are decreasing, though blooms remain present in some areas, prompting continued caution. Recent tests show toxin levels are generally below recreational advisory limits, but the South Carolina Department of Environmental Services advises avoiding direct water contact in areas where blooms persist, especially for pets. Blooms were first spotted in early April and have since spread across the lake. Harmful algal blooms, common in warmer months, can cause symptoms like skin rash and stomach pain. They thrive in slow-moving, nutrient-rich water and can resemble foam or discolored water.
