Boardman River Feasibility Study - Alternative 43 (Draft)
Subject
Boardman River Dam Project; Alternative 43Abstract
This fact sheet is a summary of a detailed analysis of the alternative described below. The alternative was selected
by the Boardman River Dams Committee for detailed analysis along with five (5) other alternatives. The following
information is provided as a summary of the analysis of the alternative. Information on the existing conditions and
impacts of this alternative can be obtained by reviewing the complete report on the website. You may notice that the
description of the analysis of the alternative sometimes includes at the end of certain sentences an alphanumeric
code in parentheses. This code refers to the list of questions that was included in the Request for Proposals.
Description
This option would consist of retaining Union Street Dam, along with the existing fish ladder and DNR weir operation.
The fish ladder would be operated to allow salmonids to pass the dam, but invasive aquatic species would be
blocked at the weir and Union Street. Sabin Dam would be removed completely to allow a free flowing river to be
restored from Boardman Pond Dam to Boardman Lake. Boardman Pond would be modified to meet MDEQ
requirements and the water level maintained at the water level prior to the drawdown. Gates and other water level
controls will be used to provide flood control in Boardman Pond. The dams at Boardman Pond and Brown Bridge
Pond will be modified to allow passage of Great Lakes fish, including salmon and trout. The Brown Bridge Dam will
be modified to allow for cold water at the bottom of the impoundment to be discharged, which may mitigate the impact of warm water discharge into the Boardman River.
