Just for clarification...the south side of the causeway is all private property...several well-to-do Torontonians purchased the whole swamp for their own pleasure...
Way back when a Mr Purdy built a dam and mill at Purdy Mills (200+ years ago...renamed Lindsay Ontario 150 years ago) and was allowed to flood 65,000 acres of land along the banks of the Scugog River...that became Lake Scugog...
Because our farm extended out under the water, my grandpappy used to run a trap line for muskrats and mink in the winter...
Don't know all the details of the land purchases but it all belongs to the private club now and they keep it well patrolled in case anyone is thinking of dropping a boat or canoe in there...
