Lifting Device Developed to Remove Stoplogs at Ivanhoe Lake Dam

The seven spillway bays at Ivanhoe Lake Dam are controlled by stoplogs, with frequent installation and removal from March through November to control the lake level. The old system of manipulating the stoplogs using a an overhead gantry system was difficult and dangerous for personnel during high flow events. Dam owner the Ontario Ministry of Natural Resources (OMNR) worked with Hatch Energy to develop an electric overhead stoplog lifting device that can be remotely operated.
