Complete question: If NEORSD removes Horseshoe dam and Lake, then the resulting new dam at Lower Lake will need to be much larger, destroying the beauty and historical significance of the present restoration. Wouldn't restoring the existing 2 dams be the more secure and beautiful option? Furthermore, the 2-mile, 20' wide, multi-million dollar Doan Tunnel already being built in Ambler Park is immense. Assuming that holds enough storm water to solve the problem of flooding in University Circle, why has NEORSD stated that Horseshoe Lake has to be removed to solve flooding there?
Answer: The design and materials originally used to construct Horseshoe and Lower Lake Dams do not meet the current safety standards for a Class I dam. ODNR Dam Safety Program requires modern engineering and materials specifications to ensure the protection of life and property per the Ohio Revised Code. The Doan Valley Tunnel was constructed to control combined sewer overflows at 11 locations along Doan Brook; the tunnel was not constructed to mitigate flooding along the brook.
