Auteur : Société d'énergie de la Baie James,Note :
When the gate is lowered, the leaves are in horizontal position with one leaf lying on top of the other. The two leaves have a sliding seal or hinge at their juncture and are sealed against the piers at each end. When pressure form healwater is applied in the chamber underneath, the gate can be raised to any desired height so long as the two leaves remain in contact. The water pressure under the gate is regulated by an adjustable weir or by the setting of inlet and outlet valves in a control chamber in the abutment of the spillway.
