The fishing here is always good in the summer. It's the heat that is the issue. The heat is not the problem when you are down there as it is like an oasis. It is the walk out. Make sure to take plenty of water. The fish are very active. Most any fly will do the trick here just keep it 16 and smaller. I typically use a size 16 yellow or orange stimulator with a flashback bead head pheasant tail or a tiger midge as a dropper
