Spring is just around the corner and Resolution Guide Service is gearing up. During spring (March, April & May), fish are out of their winter holds and feeding. The best spring patterns are midge, annelids, eggs, dry flies and streamer. The San Juan River rich waters spawn abundant flora, which in turn creates a fine environment for insect proliferation, which in turn supports one of the most prolific trout populations in any large river, both in terms of quantity and average fish size.
