Lake Clarke

Please be advised that high-water conditions have washed away normal warning devices (buoys) at Safe Harbor & Holtwood Dam. 

Once conditions return to normal and it is safe to do so, the warning devices will be re-installed. 

Please use additional caution when on the river. Pay attention to your surroundings and respect all signage. 

Also, due to these conditions, the flashboards at Holtwood Dam were washed away. As a result, please expect low water levels until replacement work can take place.

Please be advised that Brookfield Renewable has deployed a new mobile friendly website for all water data pertaining to their assets. Users should visit and bookmark for all future data needs. Please be safe on the water!
