GREEN BAY -- The Department of Natural Resources invites the public to comment on its Strategic Analysis of Fish Passage at Dams.

Fish passage describes the ability of fish to move upstream and downstream to find suitable habitat and breeding grounds. While unimpeded fish movement in rivers was recognized as important well over 150 years ago, technology development to effectively pass fish around or through dams has been slow, with much trial-and-error. The topic of fish passage at dams involves many DNR programs and has become increasingly complex.

This strategic analysis is an informational document for the public, the department and natural resource policy makers to better understand the topic and to aid in the crafting of future fish passage initiatives. It summarizes our best current information on fish passage, the known and possible environmental impacts, applicable regulations and potential policy approaches.

The strategic analysis and links to more information about fish passage at dams can be found by searching the department website,, for key words "fish passage."

Comments on this Strategic Analysis may be submitted through Oct. 16, 2017, by email to, or sent via US Mail to Jim Doperalski Jr., environmental analysis and review specialist, 2984 Shawano Avenue, Green Bay, WI 54313
