This area is called the intake hole. The city of Aberdeen has a water plant at this location.
The spillway/dam is not large. You can walked your boat around the east side of the spillway.
There is a sign hanging over the water before your arrive at this location warning of danger.
We have always empty our boat of any real prize possessions and attached a rope to the boat. We would walk on land,there is room, and allow the boat to float over/around the end. The power of the current is incredible it will attempt to suck your boat back into the the dam causing it to fill with water. Probably the most import think to remember is to take time to walk your boat and don't fool around trying to get an extra cast in before you get to the spillway. Pay attention! you have plenty of time to get out of your boat and do the right thing.
