The swollen Savannah River is starting to spill onto the Jessye Norman Amphitheater along the Riverwalk in downtown Augusta.
The amphitheater is completely roped off. Richmond County deputies are patrolling the area and keeping people away.
Augusta city leaders have closed the lower portion of the Riverwalk. They have also put up a levee barrier at the lock and Dam and closed Butler Creek.
More rain is expected Thursday afternoon.
