Parks Canada raised the water levels on the Tay River and Christie Lake in part to maintain water levels on the Rideau Canal. “Parks Canada did perform operational work to increase the outflow from Bobs Lake dam,” wrote Aarin Crawford, a public relations and communications officer with Parks Canada’s Rideau Canal Ontario Waterways section in Smiths Falls, in an email exchange with The Perth Courier five days following the initial request. “The outflow increases were conducted to compensate for evaporation demands in the navigation section (of the) Rideau Canal.”
