Hello from West Yellowstone, MT – the Trout Capital of the World!

The fishing season in Yellowstone Park ends this Sunday, and weather is looking good, so get it while you can! This historically marks the end of our own busy season, and as such this will be our last weekly report for the year. We plan to chime in throughout the winter as we work on new instructional content, and get out fishing here and there as weather permits. Thanks to everyone who has followed along with us, and given us the feedback that we need to make our fishing reports and newsletters more useful for everyone. Thanks also to everyone who visited us during this crazy summer, and for helping us to keep everyone safe and healthy.

Some of the guys have been getting out of town lately for a little break after a great summer. Joe went bird hunting, a type of therapy that come to him in no ther way. Justin, Chris, and Marco headed a bit farther west in search of steelhead this week, and knowing how steelheading is, that can either be therapy, or force you to seek out some therapy after the trip! Whether you are into fishing or hunting, or the start of skiing, or another outdoor activity this time of year, get out there and enjoy it!

Remember, folks, this is the time of year where some of those big brown trout that we all love are already spawning. Brookies as well. Please, if you choose to fish waters with those species in them, be extra aware of your surroundings. Absolutely DO NOT target trout that are on or near redds. No hero shot is worth threatening the reproductive success of a wild trout. If you see fish doing their thing, just stay back so as not to disturb them, and enjoy one of natures great spectacles that few folks get to experience. And, when you are wading, keep an eye peeled for that clean gravel as accidentally stomping on trout eggs is every bit as bad as fishing for actively spawning fish.

Big Sky Anglers is OPEN from 8:00am to 6:00pm through this Sunday. After that we plan to close up for inventory for a bit, but if you need anythign, be sure to give us a call and we can organize for a curbisde pickup for you. We will pick up with winter hours after that, so stay tuned for that. Our fly shop remains a clean and healthy environment for both our customers and staff members. There is a sanitation station at the door complete with hand sanitizer and masks if you don’t have one, we are still under Governor’s mandate to wear them when 6′ of social distance isn’t possible indoors; the staff will continue wearing masks for the future. Stop on by, say hello and we’ll get you taken care of. Most importantly, stay safe, stay healthy, and enjoy your time outside.

Take care and fish on,

Henry’s Fork – by Jonathan Heames

Island Park Dam:  176 cfs Ashton Dam:  900 cfs

As we approach the end of the Yellowstone National Park fishing season, keep in mind that there are always options here in Yellowstone country for a day’s fishing, and the Henry’s Fork is no exception. There is fishable water throughout the system, the main closure being Harriman State Park, the Raillroad Ranch, which remains open through November 30th. It is closed from December 1st through June 14th.

The Box canyon will remain a good bet anytime the mercury doesn’t drop so far that you wouldn’t want to be in a boat, anyway. Small zebra midges and mayfly nymphs, dead-drifted streamers, swung leeches, and rubber legs will all produce results over the coming months. Eventually, snow will drift in and we won’t be able to launch a boat down there anymore, limiting access to wade anglers.

The Railroad Ranch is still producing daily baetis (BWO) hatches, these will be stronger and last longer if you have cloudy days, but they’ll still come off on a sunny one for now. The larger trout usually will respond better when there are clouds around, but any day worth walking is a day worth fishing right now.

The coming months are a good time to limit your endeavors in the canyon country downstream of Riverside on to the confluence of Warm River to wade fishing and the nicest of days. From Warm River on down to Saint Anthony, good fishing will be found through the fall and throughout the winter months. Again, cloudy days will provide the best opportunities for dry fly fishing, but it’s hard to argue with a sunny day in the coming weeks for the pleasure of being outside in it!

If you are heading to the Fork anytime this winter, be sure to give us a call at the shop, we’ll continue to fish down there throughout the year and will usually have a solid report for ya!

Yellowstone National Park – by Matt Klara

Sunday, November 1st is the last day of the fishing season in Yellowstone for 2020. We had some frigid weather last weekend, we are seeing the fisheries more seriously affected by low water temperatures. The NE corner of the park is officially off our radar until next summer.

Our focus during these final days of the season will be on the waters in the western region of Yellowstone: the Firehole, Gibbon, and Madison Rivers. All three of these iconic watershed benefit from an influx of warm, geothermal water providing good opportunities.

With overnight lows expected to be in the teens, with afternoon highs in the mid 40s through the weekend, there should be some great chances to get out for one last flick in YNP.
Look for hatches of Fall Baetis on the Firehole in the afternoons. Keep in mind the Firehole has a great many micro-habitats because of the varied influences from geothermal sources. If the bugs aren’t rolling at Fountain Flat, that doesn’t mean the same is true below Midway Basin.

The Madison River in YNP remains a good bet for lake run fish. Good numbers of fish are now available throughout the system. Browns will be a mix of new entries to the system as well as those that are settled, staging, and/or actively spawning. Keep an eye peeled and leave those fish alone. Remember, fall run rainbows eat flies well and run hard like a mini steelhead.

The Madison River in Montana will continue to provide decent days in the coming week and month, efforts are best focused in the wade sections, both from Quake Lake to Lyons Bridge and from Ennis to Ennis Lake.

In the upper wade stretches, decent nymph fishing will be found starting late morning, with a daily baetis hatch occurring some time during the middle of the day. The biggest factor to watch out here is the wind, if it’s blowing hard in the valley, the days can be a struggle, if not, it’s usually a pretty nice place to be and the scenery is first class! As winter looms closer, baetis will give way to midges, prompting smaller nymphs like zebra midges and fuzzier dry flies, like Joe Moore’s Comparabuzz.

Below Ennis there is some streamer fishing to be found in some of the runs as brown are moving up the system from Ennis Lake. There are some runs worth swinging over these next couple of weeks, after which angling efforts will be better focused further upriver.

The Lakes – by Matt Klara

That blast of super cold weather shut us lake fans down for a few days at least. Many of the smaller and shallower bodies of water froze over last weekend, including parts of Henry’s Lake. While the ice anglers begin licking their chops, flyrodders have fingers crossed that the warm afternoons that are here this week will extend the stillwater season just a bit longer. As usual, late fall cold water fishing may require a low and slow approach, either on sinking lines or with balanced leeches under an indicator. Get it while you can, because hard water season is coming fast!
