Ohio Dam Removal Unlocks Creek's Flow

In Ohio, an 80-year-old concrete dam, the Cloverlick Dam, is undergoing removal as part of a significant restoration project. This structure, built in the 1940s to supply water to the Village of Bethel, has outlived its usefulness, especially since Bethel ceased operating its water treatment plant in 2006. The dam's removal is a key component of Ohio's H2Ohio initiative, a statewide program dedicated to enhancing water quality and conserving natural resources. The Ohio Department of Natural Resources initiated this project in October 2026, collaborating with various local and federal agencies.

The Cloverlick Dam, standing about 12 feet tall and 200 feet long, has disrupted the natural flow of Cloverlick Creek. This interruption has led to sediment and nutrient accumulation, warmer water temperatures, and reduced oxygen levels, negatively impacting aquatic life and causing the creek to be classified as impaired. The restoration project aims to re-establish connectivity across the 14-mile creek and its 70 miles of tributaries, facilitating the movement of fish and other organisms. This reconnection is expected to improve habitat quality and the overall condition of the creek's ecosystem, which eventually feeds into William H. Harsha Lake, a vital drinking water source.

Beyond ecological benefits, the removal of the Cloverlick Dam also addresses public safety concerns. Low-head dams like this one can create dangerous recirculating currents, posing a risk to swimmers and recreational users. The project is anticipated to make the creek safer for activities such as kayaking and fishing. Funding for this extensive restoration effort comes from the H2Ohio Rivers Program, contributing $920,000, and an additional $1.1 million from the federal America the Beautiful Challenge grant program. Substantial completion of the project is expected by the fall of 2027.
