Do yourself a favour...take spinning rods too, with coffee grinders and lures...like Mepps spinner, normal hooks for bait-fishing, etc. They can be difficult on fly...so if nothing works, crank some mepps spinners or Rapala crankbaits through the water. Then when you've caught a MENEER (okay, Mevrou...only the females get really big... ), then switch to fly again.
