In late May, we went out to East Pit Lake, which is about 1km north of the Wabamun Village exit on Highway 16. This is a man-made lake over an old quarry (the whole areas looks to have been strip mined about 25 years ago).
The lake itself is about 1.5 km long and maybe half a km wide. We did a full circuit in about an hour taking our time.
There were also some beaver, an osprey, loons, mergansers, and lots of red-winged blackbirds.
