Fish passage considerations for developing small hydroelectric sites and improving existing water control structures in Ontario

Unfortunately fish passage is rarely even considered for hydroelectric facilities in Ontario; however, this report may indicate the beginnings of positive change.

Fish passage has long been recognized as an important consideration in managing Canada’s fisheries resources. A decision-making framework developed in British Columbia provides one of the most comprehensive ways to approach fish passage resolution at a proposed project. This process outlines assessments of environmental, financial-technical, and social benefits or the “BC triple bottom line”, in determining the need for fish passage. In addition to such a framework, it is important to note that the decision making process frequently relies not only on enabling legislation and policy, but on technical issues, the interpretation of the latest research results, as well as in-depth expertise on fish passage. Often, in-depth knowledge can make a difference, particularly when data on fish and fish behaviour are lacking.

This document is a collection of events and recent developments related to the re-introduction of Lake Sturgeon in the Upper Reach of the Mattagami River near Timmins Ontario.

It was back in 2002 that the Ontario Ministry of Natural Resources approached Club Navigateur La Ronde and the Timmins Fur Council to be partners on a project to re-establish lake sturgeon population in the upper reach of the Mattagami River near Timmins Ontario. In the Lands and Forest archives of the early 1900s were records of sturgeon spawning activity observed at Wawaitin Falls by a conservation officer of those early years of the Porcupine mining camp. Log drives, dam construction and subsequent operation combined with fisheries led to population drops to unsustainable levels. Continue reading
