The CRT, ratified by the United States and Canada in 1964, led to the construction of three storage dams in the Basin (the Duncan, Keenleyside and Mica dams) and one in Montana (Libby Dam).
The modern, large lake was created after the completion of the Mica Dam in 1973, and was called McNaughton Lake (after Andrew McNaughton) until 1980.
The park may have been saved because the British Columbia government was preoccupied in the 1960s with planning and building (and paying for) the W.A.C. Bennett Dam on the Peace River and Mica Dam, Keenleyside Dam and Duncan Dam, all part of the Columbia River Treaty projects.
