Yellowstone River Closure & 2016 Summary

Missouri River Brown Trout

Our 2016 fly fishing season certainly was dramatic with the temporary Yellowstone river closure. Let’s first discuss the actual fishing – which is always the easiest part. Our early season fished fantastic from April until early July on the Missouri River, Paradise Valley Spring Creek and the Yellowstone River.

– At times per usual from April through June the Missouri fished outrageously good. The lower, but consistent river flows made for steady nymphing (both deep and short leash). Dry fly fishing was a bit more variable as cooler weather and water temperatures made for limited opportunities.

Paradise Valley Creeks – DePuy Spring Creek in particular fished good as usual during this timeframe. Good numbers of fish and relatively consistent hatches provided excellent sight fishing opportunities. Baetis (Blue winged-olives) in the early season and PMD’s (Pale Morning Duns) throughout the latter part of June made it the reason most anglers return year after year.

Yellowstone River – the unusually early season run-off made for some excellent late season June fishing. Salmon flies were not prolific, however the summer caddis, Golden Stones and other less prolific hatches were quite good.

Mid Summer fishing (July through early August) – the Boulder River, Stillwater River, Yellowstone were rather inconsistent at times, but our veteran MFG guides made the best of the opportunities. Highlights were probably the early season in Yellowstone Park on the Lamar and Soda Butte Rivers. Productive, consistent hatches with larger than average Cutthroat numbers made for memorable highlights for nearly all of our anglers.

Now to the dramatic events of the 2016 season. On August 19th the Montana Fish Wildlife & Parks (FWP) closed the Yellowstone River and all of the tributaries connecting to the river. This action was unprecedented in Montana and the West in general, and based on the unusual die off of an estimated 4,000 Mountain Whitefish. In the subsequent research it was found the die off was attributed to an invasive parasite that effects both trout and whitefish. The river and tributaries remained closed for about 2 weeks until it was revealed that only a few trout failed to resist and died from the parasite. Let’s emphasize that last statement – only a handful of trout died. In light of that research and cooler water temperatures, in which the parasite does not thrive, Montana FWP lifted the closure on the majority of tributaries and the Yellowstone River itself.

Yellowstone River ClosureTo summarize the Yellowstone River closure of 2016 – few trout were effected and the majority of fishing restrictions were lifted within a couple weeks time. How did this effect fishing? Other than some limited float fishing options for anglers it really wasn’t much of an issue. At Montana Fly Fishing Guides, llc. we take you to the best possible fishing – so as the Yellowstone hadn’t been the best option in the week leading up to the closure we’d already started taking anglers to other waters that had been fishing well. This TripAdvisor Review pretty much sums up our time during the Yellowstone River closure:

My husband and I had a great time fly fishing with our guide Zach!!! He is awesome!! Eric set everything up for us and he was so helpful with everything. He quickly calls you back and answers e-mails. With the Yellowstone closing several days prior to our trip we were a little nervous about what to expect. Both Eric and Zach helped to make the trip amazing. We will def. be back!!!!

So as the winter season progresses and we get some more data on fish populations this spring we’ll keep you posted. However, in the mean time make sure to start planning your 2017 Montana fly fishing trip now so you don’t miss out on your preferred guide, lodging or fishing location. We’ll look forward to seeing you this coming fishing season.

  1. Hi Eric,
    This is Jim Piper, Roger Hoh’s friend. Glad to hear the river was only closed a couple of weeks (right after we were there in August I think). We are looking forward to our trip this coming August, and hope the fishing will be good! I’m writing to recommend a book I just started called “A Good Life Wasted Or Twenty Years As A Fishing Guide” by Dave Ames. You’ve probably already read it, but if not I know you’ll enjoy! Btw, congrats on the web site, my first time on it, very impressive!
    Regard, Jim

    1. Jim – good to hear from you. Yea, that was a relief when the opened it back up. Fishing should be good this season. The PKD disease didn’t effect the trout as much as they thought, mostly just whitefish. We also are having a good spring, so we should have lots of cold water this season.
      I’ve read that Ames book a couple times – it’s really good.
      Glad you like the site! It’s been 17 years in the making and the latest facelift has been a huge improvement.
      See you this summer!
