It seems to be a part of chain of lakes in a old glacial meltwater valley, including Saunders Lake and perhaps Telford Lake, that eventually turned into the ox-bow hell of the Battle River.
We accessed the lake at the south end from Coal Lake provincial park. The lake access was not signed but was reasonably easy to find. We travelled east-bound on Highway 13 then took the second left once down the valley. Most notable land mark is a logging truck fixed atop part of an oil derrick (you'll know it when you see it...).
There are pit toilets, a boat launch, a parking lots and a jetty here. Access was good and the water was reasonably clean. The carry was about 25 feet--which is hardly worth mentioning.
The lake is long and it was windy when we were there. The sides of the lake were nice and calm and there were only a few power boats out fishing. We went north on the east side, got bored, turned back and then cut across to the west side (below).
There are lots of bird here. At the south end of the lake, there is a bit of a swamp with channels to explore and lots more birds. The biggest we saw were a bunch of pelicans.
We sent probably half and hour in the swamp, watching birds and cutting among the reeds for open spots.
Overall, a nice enough lake. I'd be worried if a big wind came up as there is no where to hide!
I'm not sure we'd go back although there is also access at the north end of the lake.
