As of May 25th, the Gunpowder River has dropped down to 38 CFS and is ranging between 46-53F. With no rain in the near future, it is expected to stay low for a while. This will cause the need for longer and lighter leaders. Fishing a 10-12ft leader will greatly improve your drifts in the low water. It is best to avoid the slower water as fish will have lots of time to analyze your fly and the fish generally spook much easier. Target the riffles and deeper pools for the most success.
In the morning, we have had success swinging wet flies through the riffles in between pools. This has been an easy and successful method to catch fish consistently. As the water warms up throughout the day the sulphurs are prevalent. Again, the riffles will be more productive even while fishing the dries. Nymphing is still an effective method on the river when the water is low, however it is key to target the deepest water and limit your disturbance in the pool.
