I checked with the Deschutes National Forest this morning (they had a person in charge of getting info out to the outfitters on fire related closures which I thought was awesome on their part) and she said access to Little Lava Lake and Lava Lake are now open too. 
However, Helicopter are still dipping water at Little Lava, and my advice for the safety of yourself and the safety of those brave pilots is to give it a rest and let them do their job without having to worry if Jeff’s drift boat is in the way, or Ed’s pontoon boat or Kris’s Float Tube….(names may or may not have been changed to protect the innocent- HAHA)
