Pacific Power discovered the leak in the dam last week. It apparently is in one of the wood panels holding the dam.
Bob Gravely with Pacific Corp says they are still assessing the long term future of the 100 year old facility.
"This is now the third instance that we've had a leak in the last five years. We want to go in and take a broader look overall at the condition of the dam. But this is the third leak in five years, we'd like to know if this is going to be happening to other portions at the dam. And we need to make a broader decision whether to keep making these fixes, if its going to be happening regularly now."
Gravely says water levels have stabilized since Saturday night, but levels remain about two feet below normal levels.
