Dam fix requires Rock River drawdown

Janesville Gazette


Q: What parts of the river will be affected?

A: The river will be lowest upstream from the dam.

Don Bush, fishery biologist for the Department of Natural Resources, thinks the impact will be most significant 2 to 3 miles upstream.

Presny agreed, adding that the impact will be felt about halfway to the Indianford Dam.

Downstream, water levels will be extremely low throughout downtown and all the way to the Monterey Dam, Presny said.
