Officials say White Clay Dam may become unstable, threaten downstream population

PINE RIDGE, S.D. — According to a message from the BIA Safety of Dams Program, the White Clay Dam is now being monitored as it may potentially become unstable. Residents that are at risk are being notified to standby and prepare for evacuations if necessary.

They say the situation is a Response Level 2, meaning a rapidly developing situation in which conditions are more serious than a Response Level 1.

The situation was noticed during a routine inspection of the outlet works. Sediment was found in the outlet lines where, under normal circumstances, there should be none.

The public has been asked to stay away from the spillway or pump house areas.

If you have any questions, you can call the BIA at 867-5126 or OST Emergency Management at 867-5011.
