Sources for Streamflow Data

Posted on March 4th, 2021 in Fishing Tips

Virtually all fly fishing guides and outfitters in Montana watch streamflow data and streamflow forecasts like hawks, especially during runoff season (that is to say: right now) and when summer thunderstorms are rolling around. This is no different than farmers watching the weather forecasts. Here are the important sites to allow YOU to check streamflows, both right now and expected flows for the days ahead.

Montana Streamflow Data: This site returns data from all USGS gauging stations in Montana. The site is organized by river drainage, then from upstream gauging stations to downstream stations. In my area, the Yellowstone Basin graphs from the Lamar River in Yellowstone Park down to the graph at Springdale are the graphs I use most often, with the Stillwater graph secondary. By far the most important graphs for general streamflow are the Corwin Springs and Livingston graphs on the Yellowstone, while the Lamar and Gardner graphs are important for telling me about sudden rises in water level (which are almost always accompanied by mud) due to storms.

Advanced Hydrologic Prediction Service – Billings: Here’s the streamflow prediction site for eastern Montana. This site shows flow graphs noted in the previous link, but also shows predicted flows for the next few days for most gauging stations. The basic graph pictured below is most useful during the spring runoff season when we are trying to plan for future trips based on weather forecast. If you’re looking at a big predicted bump coming up, it’s best to get fishing beforehand, because that bump means mud.

This site also includes an option to view “Probability Information.” This is a longer-range forecast of predicted flows, but it isn’t updated very often and I often find it inaccurate. Here’s a sample graph of probability information:

Select the above graph by clicking the dropdown menu off the lower right corner of the graph, then selecting “Flow – Weekly Chance of Exceeding Levels.” This is most useful to anglers, as flow rather than gauge height determines fishability. Too much water and things are too rough, and probably muddy to boot.

Top Missouri River Nymphs in March

Posted on March 4th, 2021 in Fishing Tips

Intro to Top Missouri River Nymphs in March

Late winter and early spring are “pink season” on the Missouri. Top Missouri River nymphs in March are almost all pink. Whether the fish are taking these assorted pink bugs as eggs or dead scuds and sowbugs probably depends on the specific fish. Nonetheless, they work. The key is generally getting them down. These flies should be ticking bottom just on the edge of the current seam in 5-8 feet of water in slow walking-speed runs.

Rainbow Czech Nymph

This is a great multipurpose nymph that can look like a sowbug, scud, egg, or even a caddis larva. Also try it with the bead replaced with a fluorescent flame “fire bead.” Another good similar pattern is the AMEX, which basically just swaps the abdomen and thorax colors around and replaces the shellback with a tinsel wingcase over the thorax alone.

  • Hook: #12-18 scud. Note that you can also tie this fly as a “jig nymph” with the proper hooks and beads.
  • Bead: gold brass or tungsten
  • Thread: 6/0-8/0 black, pink, or tan.
  • Shellback: clear scud back.
  • Rib: black wire or midge/micro tubing.
  • Abdomen: Wapsi rainbow sow-scud dubbing (note that the Wapsi product is far better than others for this fly).
  • Hotspot/Thorax: Bighorn pink sow-scud dubbing, or other hot pink dubbing.
  • Head: one or two turns of rainbow sow-scud dubbing.

Pink Firebead Soft Hackle Sowbug

Various bright pink sow/scud patterns are always favorites on the Missouri at this time, and some get surprisingly complicated. Most years, I do better by following the KISS rule. You’ll use up a lot of firebead flies, mostly because the beads get banged up and lose their effectiveness, and it’s easy to fill your box with this pattern. Experiment with different shades of pink on the body (I typically carry four subtle shades) and tie some of each with light dun and some with cream or white hackle.

  • Hook: #16-18 short shank nymph.
  • Bead: fluorescent fire orange brass or tungsten “fire bead.”
  • Thread: fluorescent fire orange 8/0
  • Body: pink dubbing blend.
  • Hackle: one or two turns of light dun, cream, or white hen.

Pink Lightning Bug

This one likely crosses over between eggs, scuds, and Blue-winged Olive mayfly nymphs. There are many competing variations of this fly. I’ve given the recipe for the one I use the most. Don’t hesitate to experiment with different tail materials, bead colors, metallic or translucent pink body materials, and dubbing blends for the thorax.

  • Hook: #16-18 scud.
  • Bead: nickel brass or tungsten.
  • Thread: hot pink 8/0.
  • Tail: A few strands of shell pink Antron yarn, or similar yarn.
  • Abdomen: pink Holographic Flashabou.
  • Rib: extra small red Ultra Wire.
  • Wing Case: tag ends of abdomen Flashabou.
  • Thorax: pale pink dubbing blend

Late Fall Yellowstone Fishing Trips

Posted on February 1st, 2021 in Fishing Tips

Introduction to October Fishing Trips in Yellowstone

Late fall begins when the first extended cold weather hits, usually around October 1. October fishing in Yellowstone is not for the faint of heart, but it is fantastic for the right anglers in the right places.

While fewer waters fish well at this time than earlier in the year, simply because most waters are already at winter-low flows and have cold water temperatures and lethargic fish to match, those that do fish well at this time fish really well.

The best waters are those that host fall-run brown trout, though nowadays we often focus on the non-spawning trout that follow the brown to eat their eggs and the bugs their spawning behavior disturbs, rather than the browns themselves, both to avoid stressing actively-spawning trout and to avoid the crowds the spawn can bring to the best areas.

That said, the largest numbers of “big brownies” are present in late fall, and unlike in late summer and early autumn it’s seldom necessary to get on the water early if you want to chase these fish.

On the other hand, the weather can be horrendous, with heavy snow and temperatures in the teens more than feasible by this late in the year. As noted above, many waters are simply too cold to fish well by October. An additional unwelcome development in recent years is massively-increased guiding and fishing pressure targeting fall browns, which is one reason we now spend more time chasing the non-migrants on brown trout rivers, since these fish fall between the cracks a bit.

Full confession: I caught this one. Despite the good fishing for large fish, business falls off in late fall. Fewer people want to visit Montana when it might be 20 degrees and snowing, I guess. I’m not alone among Montana outfitters in that I do a high percentage of my own fishing in late autumn.

Important Note on Fishing Ethically During the Brown Trout Spawn

The brown trout spawn begins around October 15. We target browns more aggressively beforehand, since we can be certain we aren’t pursuing active spawners or damaging spawning areas.

After October 15, shallow areas with fist-sized rocks and gravel and steady currents fill with brown trout that are actually settling down to make the next generation. It is unethical to fish in these spawning areas and extremely destructive towards the next generation to do so. We never fish for actively spawning brown trout on our Yellowstone guided trips.

Any guide who does so is unethical and unprofessional and does not deserve your money. If you decide to fish spawning areas on your own, expect thorough tongue-lashings from anglers who fish ethically who happen to see you doing it.

If you didn’t know better about fishing for wild actively-spawning brown trout before reading this, now you do.

There’s no reason to worry: the deep pools and turbulent boulder-bottomed water where the big browns rest on their journeys to their spawning areas hold plenty of fish right up until the park closes. These include both pre-spawn fish on their migrations and post-spawn fish that are done “doing the deed.” Rest assured you can still catch big fish without fear of stressing the active spawners.

Early Fall Yellowstone Fishing Trips

Posted on February 1st, 2021 in Fishing Tips

Introduction to Early Fall Yellowstone Fishing Trips

Early autumn in Yellowstone, generally meaning the month of September after nights start getting cold but the first heavy low-elevation snows have not fallen, offers the widest range of fishable waters of any season. Except for most small streams, which get too low and cold, virtually all water in Yellowstone Park can fish well in early fall.

For those who like match-the-hatch mayfly fishing, this is an ideal period, since mayfly hatches abound on all larger streams. It’s also a good chance for those who are willing to get out first thing in the morning or during the ugliest weather to get some of the biggest brown trout of the year.

The downsides are continued crowds near the road and inconsistent conditions. While overall crowds do decline, especially after September 15, these crowds slant older and less-fit, which means that the roadside easy-access streams can be more crowded now than earlier in the season, especially when the weather is nice.

Speaking of the weather, it might be beautiful and sunny or spitting bitter cold rain or snow. These varying weather (and water) conditions also mean that on our early fall Yellowstone fishing trips we have to play where and how we fish by ear, based on what fishes well given the day-to-day or even hour-to-hour conditions.

Late Summer Yellowstone Fishing Trips

Posted on January 31st, 2021 in Fishing Tips

Introduction to Late Summer Yellowstone Fishing Trips

Late summer, which begins in late July or early August and continues until the first cold nights in late August or early September (henceforth just called ‘August’), continues to offer excellent hike-in fishing, and both the hikes and the wading are usually not so onerous at this time as in early summer. In addition, this is prime time for small, rough mountain creeks that might still be too high in early summer. Regardless of locale, August Yellowstone fishing trips are excellent bets for anglers who like fishing terrestrial dry flies, and can turn out some big fish on subsurface flies, as well.

The downsides of late summer are continued crowds, especially on famous waters that flow through meadows, and potentially low, clear, and somewhat warm water than might mean we have to start fishing early in the morning and quit at midafternoon to avoid stressing the trout. The latter issue is much more common during drought years.
