Recreation

The lake is a popular outdoor destination providing boating, fishing, wildlife habitat, and is nestled against the Big Belt Mountains of the Rocky Mountains. Canyon Ferry Lake has also become a leading ice boat venue for iceboat racing and iceboat world speed record attempts.[1][2] The former town of Canton lies beneath the lake, having been submerged following construction of the dam.

gollark: I think politics is probably about as controversial as theology. Most people here are probably not the demographic to care much about theological conflict stuff.
gollark: We probably only need info, introductions/welcome (could be merged), computers, maths, politics/economics, general "things" (#3d-printing/<#694964719135490078>/<#677752722761711618>/<#677667174826901513>), media (music, creative works, video games, misc and links), images/things in the world (aviation/images/luxury hotels/surface transport/restaurants/pets).
gollark: I feel like this is an unproductively large number of channels.
