In order to monitor improvements made to the Robert S. Kerr Dam spillway in 2024, the Grand River Dam Authority is making the public aware of a planned exercise to temporarily raise the elevation of Lake Hudson.

The plan calls for the lake to be brought to an elevation of 630 feet if current inflows are sufficient to achieve that level. It would then be held there for a three-day observation period. Lake Hudson’s normal pool elevation is 620 feet.

Although the work on the spillway was completed last year, recent heavy inflows into the Grand River watershed were necessary to facilitate this monitoring exercise. Barring any further heavy rains or watershed inflows during the observation period, a drawdown to Lake Hudson’s normal elevation will commence following the exercise.

GRDA will provide updated information on Lake Hudson’s elevation when the exercise is completed.
