APPLICATION BY THE ST. LAWRENCE SEAWAY AUTHORITY TO THE INTERNATIONAL JOINT COMMISSION TO EFFECT PARTIAL CLOSURE OF A SECTION OF THE ST. LAWRENCE RIVER BETWEEN TOUSSAINT ISLAND AND PRESQU'ILE

NEAR IROQUOIS, ONTARIO

Ontario Hydro has reviewed the International Joint Commission's Public Notice of the above application and the, Application itself. Also, through its representation on the International St. Lawrence River Board of Control, Ontario Hydro has knowledge of the study by the Board of the proposed partial closure of the channel.

It is Ontario ~ydro's view that, based on the present available data, there should not be significant adverse effects from the closure on ice-forming velocities or on head losses in the river. However, measurements and observations for a considerable period following construction will be necessary to determine accurately any such effects. It is understood that the Board intends to monitor levels and flow data following construction and report to the Commission any detrimental effects materially different than those determined in the study. On the understanding that this monitoring will be done, Ontario Hydro has no objection to the construction of the causeway for the improvement of navigation conditions.
