SALEM, Ohio- The Ohio Department of Natural Resources began the process of repairing a dam inside Ponderosa Park Thursday morning.

ODNR officials said the Dunn Eden Lake dam needs to be breached, but that the owners of the park have not done anything to address the problem.

Inspections show deterioration in the dam that dates back nearly 20 years that could pose a threat to drivers on Route 45 if the work isn't done.
