Santee Cooper to Increase Controlled Spilling at Santee Dam

MONCKS CORNER, S.C. – Heavy precipitation throughout the area and in the watershed feeding the Santee Cooper Lakes has increased inflows to the Santee Cooper Lakes system. To manage lake levels, Santee Cooper will increase its controlled spilling operation on Thursday, Feb. 18, at the Santee Dam on Lake Marion.

The flow began yesterday at noon at a rate of 5,000 cubic feet of water per second into the Santee River. Today, Santee Cooper will increase the spill rate to 10,000 cubic feet of water per second and will increase it again tomorrow.

Spill rates will continue to be adjusted during this operation depending on inflows. Updates will be posted on Santee Cooper’s Facebook and Twitter accounts.

Santee Cooper’s dams and dikes are secure. Spilling is a normal part of Santee Cooper’s hydro operations in periods of increased inflows into the lakes. Information will also be updated each business day on the lakes’ information line, 1-800-92LAKES.
