Fish passage at dams strategic analysis

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 has become increasingly complex and controversial, involving many department programs.

This strategic analysis [PDF] 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.

Strategic analysis process

A strategic analysis evaluates factual information to inform policies and approaches for contentious resource issues. This process is outlined in Chapter NR 150, Wis. Adm. Code [PDF exit DNR].

The purpose of the analysis is to inform future discussions and decisions.

Strategic analysis follows these general steps.

  1. Public announcement and scoping - defining the topics and information sources to be considered and the analytical methods to be employed. This step includes public input and consultation with other agencies and Tribal authorities.
  2. Information gathering and analysis.
  3. Document preparation.
  4. Public review - at least 45 days will be allotted for public review of the analysis, and a hearing may be held.
  5. Comment response - the department will consider all comments received, and may revise the analysis if warranted. < we are here
