Recreational Water Watch for Lake Hartwell

June 5 Update: SCDES continues to monitor the harmful algal bloom (HAB) on Lake Hartwell and record reports of observations. Based on the latest round of lake observations and water sampling, SCDES has updated the Recreational Watch for Lake Hartwell and removed certain areas of the lake, including: Tugaloo River lake arm upstream of I-85, Seneca River lake arm upstream of West Cherry Road, and Six and Twenty lake arm upstream of Centerville Road.

The Recreational Water Watch for the lake remains in effect for areas downstream of these road crossings, with the following recommendations: (1) avoid contact in areas where the HAB is present and (2) keep pets and animals from swimming in or drinking lake water where the HAB is observed.

Visit our Algal Bloom Monitoring Map to view the most recent locations where the HAB has been observed.

A new era in environmental protection.

Formerly a part of DHEC, SCDES is committed to preserving South Carolina’s air, land, water and coast through Science, Service and Sustainability.
