Yellowstone River Report 04/23/18
As reported last week, water clarity has been inconsistent. The Shields is contributing off color water that gets diluted as it makes its way downstream. We may not get the prime blue-green tinted water this spring, but if there’s at least a foot or two of visibility , it’s fishable. There have been Midges and BWOs coming off once the day starts to warm up and the sun gets on the water. March Browns are appearing more frequently and in larger numbers as well. Watch foam lines for sipping feeding fish. Nymphing with black, brown and coffee colored rubber leg patterns like girdle bugs and Pat’s rubber legs, as well as similar colored stonefly patterns is likely the best way to go unless there are actively feeding fish. Black and darker color streamer patterns like the Grinch or a black bugger are a good option in off color water as well. For dry fly action to rising fish, try a smaller size Purple Haze or Parachute Adams. With warmer weather, runoff will be here to stay. There could be a short window to fish.
