Lowhead Dam Removal Activities
Why Remove Lowhead Dams?
Lowhead dams are one of the mysterious and frustrating features of our local rivers. These are artificial structures of stone, timber or other material, which are less than 15 feet in height and extending across the channel. Ohio’s rivers are dotted with these structures, and the results are usually not good. A normal unobstructed river naturally meanders on its bed course within a floodplain, with the passage of time. But each artificial lowhead dam turns the river into a stagnant small lake in the impounded area which may stretch for a mile or more upstream. The water passing over a dam can pose lethal safety hazards and have thus been referred as “drowning machines”. Several lowhead dams are known to exist in Alum Creek.
Why were they installed? Sometimes it’s obvious– Westerville’s dam provides a pool for the city’s water intake; another small dam on our creek has a utility pipe crossing under it. But at least two significant lowhead dams- 4 to 6 feet tall each, around Nelson Road and E. Broad Street -one near the north end of Nelson Park, and one just north of the swinging footbridge between Academy Park and Wolfe Park are not believed to have any useful purpose now. The stagnant water behind them is not suitable for most fish and other diverse life that a healthy river normally can support.
FACT is pleased to expect some great changes for the better soon here, as we are moving ahead with a project (supported by US EPA section 319 grant, administered via Ohio EPA) to remove these two lowhead dams in the central urban part – between Columbus & Bexley – of our watershed. Check back here often for updates on these projects.

Penobscot River Restoration Trust, a Maine environmental coalition, has raised $25 million it needed. They will remove two of the three dams acquired from a power company and build a fish run around the third, opening up 1,000 miles of the Penobscot and its tributaries, home to most of the country’s Atlantic salmon population.
