Selkirk swamp?

I was down at what i think is the Selkirk swamp several years ago. But can't rembrr how to get there. I can remember parking then walking a ways down in and it wasn't a pond or lake but a big body of water that prolly averaged 2-3 ft deep.

Anyone have any idea on where I'm talking about or am I way off base. I do remember going thru or by Selkirk and turned on Selkirk rd. but not sure

Thanks for any help!
