Concerns Over Structural Integrity Of Shaker Heights Dam

SHAKER HEIGHTS, OH — There are concerns about the structural integrity of the dam at Horseshoe Lake, the city of Shaker Heights said. The water level will be lowered by three feet to compensate.

The Ohio Department of Natural Resources (ODNR) inspect the dam site recently, leading to the concerns over structural integrity. It is a Class I dam, the city said, which means it is critically important to insure it is sound and operable. A breach could result in property damage and risks to resident safety.

The ODNR ordered the city lower the water level by three feet. Last week, on June 19, the city opened a valve to begin lowering the water level.

"As the water drains, you will notice that mud flats develop along the edges of the lake. Do not walk on or play near these mud flats. They are dangerous and you will sink into the mud, which could require a rescue operation," the city said in a posted statement.

Once the water level of the lake is lowered, part of the masonry spillway will be removed. The city said this should help to safely control water levels during bouts of heavy rainfall. The concrete sidewalk over the spillway will be closed to pedestrians while work on the masonry spillway is being completed. Residents will not be able to complete a loop around the lake using the path.

The Northeast Ohio Regional Sewer District (NEORSD) has been consulting with the city on a long-term solution to the structural deficiencies of the Horseshoe Lake Dam. Until construction is complete, the lake's water level must be kept three feet below its regular level.

The city said it has also spoken to the NEORSD about the effects lowering the lake's water level will have on local wildlife. Since there are deep pools within the lake, there should be minimal impact to the turtles and fishes, the city said.

Construction and improvements to the dam area are expected to take two years, the city said in its statement.
