Abstract: A joint team from the St. Lawrence Seaway Authority and Hydro-Quebec had been set up to explore the areas of mutual concern relating to the combined use of navigation and power of the Beauharnois Canal during the critical periods in the spring and early winter seasons. Some improvements to existing booms have already been introduced and it has been concluded that another boom is required at the entrance to the power canal. The LaSalle Hydraulic Laboratory was commissioned to undertake a hydraulic model study for the proposed boom. The objectives are to retain ice from Lake St. Francis until required for the formation of an ice cover in the power canal, to allow passage of vessels until the end of the navigation season, and to control ice movement during spring breakup. One of the main criteria was to permit a vessel to pass through the boom system via an opening that would allow ice to arch over the opening, thereby precluding the use of complex closure mechanisms. Realization of the foregoing objectives would help in firming-up the closing date of the navigation season, and it is anticipated that an earlier opening of the season may also be achieved in this area. Furthermore, such control would be beneficial to power generation.
