Obed Lake is the western-most lake of three lakes located in Obed Lake Provincial Park, about half way between Edson and Hinton on Highway 16.
Access is clearly marked and entails a short gravel road off the north-side of the highway, which eventually becomes the boat launch. A fairly typical foothills lake--reeds, treed shoreline, sandy soil under some grass. Not a great campsite by any means (pit toilets, few sites crammed closely together, no hand sanitizer and a boil-water advisory on the hand pump).
There is a small campsite, washrooms, and picnic tables. There was a fair bit of water fowl and a collection of anglers. The lake was very warm the day we were there, maybe 15 C or so in the shallows at the boat launch. The bottom was sandy and I'd be worried about swimmer's itch.
Overall, much less nice than Jarvis Lake just 60km down the road. We stopped here for lunch on our way back from Jasper but I don’t think we’ll be back.
