The debris has been cleared and the sluice gate has been closed at the RT Orr Dam in Stratford.
Upper Thames River Conservation Authority staff have cleared the debris and with the gate closed, Lake Victoria will begin to refill.
As to how quickly the reservoir will fill and when normal recreational activities can resume will depend on rainfall.
The conservation authority continues to monitor in the Avon River below the dam. Water levels may be lowered in the channel between the dam and John Street to maintain flows downstream.
The public is still asked to watch for turtle who might be moving across the road.
