With the possible exception of pollution, hydro-electric power developments represent the most serious industrial threat to the salmon stocks. In British Columbia, as elsewhere, the post-war industrial expansion has been accompanied by an ever-increasing demand for electrical power, and this, in turn, has stimulated the hydroelectric industry's interest in many of the province's good salmon-producing rivers. There are, however, certain laws in force in Canada which require that such industries assume responsibility for fisheries protective measures made necessary by their undertakings. This paper, which discusses briefly the most common problems associated with the maintenance of salmon stocks at hydroelectric developments, is intended to give the reader some insight into the scope and complexity of these problems, and the difficulties encountered in attempting to develop economic solutions. A brief description of the life cycle of Pacific salmon is included as this is fundamental to an understanding of the basic problems.
