Yes, it did in the flood of 2005. The last I recall it was subject to the same regs. as the elbow river, so closed at this time of year. May have changed, but better check! Good luck!!
After June 15, 2009 it is open all year...5 trout limit...that being said I doubt many are left. I see this as a great lake to have a prolonged harvest of 2 trout instead of 5.
