Lake McMurtry
It's been raining a lot lately, and there is a lot of mud on the trails. Better to give it a week before riding. If you must ride, please ride through the mud not around to avoid widening the trail.
Also, if you must ride, use a wet-conditions lube and expect to rinse your bike when finished. There are hoses available near each trailhead.
There's also a lot of erosion, so expect surprises here and there.
