When you picture someone surfing, the first image that comes to mind is probably not just below the Boulevard Lake dam in Thunder Bay, Ont. A group of surfers, led by Brett Sharman, the president and founder of the Surfmasons River Surfers Association, hopes city council will be interested in an idea that could turn the lower Current River into a surfers paradise. Sharman said the proposal is to have the city alter its permit to take water from the river, to fill an artificial pool below the dam, which would act as a reservoir for an artificial wave, that would spill over for a few hours a day.
