The Ruby River is a wonderful little tailwater that has a large population of brown trout. It is mostly a walk-wade stream and best fished when flows are at the lower end and access to the best parts can be achieved. It has a large population of brown trout and nymphing is the most productive way to fish the ruby although dry fly opportunities do exist under the right conditions.
The Jefferson River starts in Twin Bridges Montana and is the result of the Beaverhead and Big Hole Rivers coming together. It flows through the Jefferson Valley before it meets up with the Gallatin and Madison Rivers to form the Missouri. Unfortunately, the Jefferson can suffer from dewatering and drought at times but under the right conditions and time of year, it can be a very productive fishery. It has strong populations of rainbows and browns and is often overlooked, a day on the Jefferson under the right circumstances will be remembered.
