Summer Heat

Summer heat has started to take its toll around the state with an increase in wild fire activity and Hoot Owl closures on many of our rivers. That being said, the Missouri is still flowing relatively cold and has not yet approached the water conditions which would dictate a Hoot Owl closure, that being three consecutive days with water temps reaching 73 degrees. We’re currently seeing water temps in the 65 – 67 degree range at the dam which means lower river temps are likely considerably warmer. It’s time to put that stream thermometer to work and start keeping track of water temps throughout the day. Once that water hits 67 it’s time to stop fishing!

Daytime highs in the 90’s all this week will exacerbate the situation but hopefully the relatively cool nighttime lows will keep us in good shape until things cool down. We’ve been starting our guide trips early (6 – 6:30 AM ) and will continue to do so until conditions improve. Traffic has thinned to the point where we’re not as concerned about the pressure on the fish but you can expect your guide to check water temps frequently and as stated above, once that temp hits 68 degrees, it’s time to quit fishing and sit back and enjoy the summer scenery.

The bite has slowed a bit but hopper fishing has been good enough and Tricos are providing daily opportunities for those who can get it done. Nymphing has been hit or miss and has been increasingly challenging with a fair amount of weeds now in the system. Warm water, hot sun, weeds….it’s August on the MO but don’t let that scare you. There are plenty of fish to be caught out there, it’s just a matter of modifying your techniques to fit the conditions and perhaps adjusting your expectations.

The crowds are gone and the bugs are here. Get on early. Get off early and leave the heat of the day to the rec floaters.

The shop is still opening at 6:30 AM Monday – Saturday. Closing time has been somewhat random as we’ve been known to cut out early when it’s blazing hot out there. We’ve officially changed our Sunday hours to 7 AM – 2 PM to accommodate staff changes as our summer crew is soon to be cut in half as Phil returns to school next week.

Should you decide to add a visit to the MO to your late summer agenda we’ve got all kinds of lodging available and could likely even come up with a guide for you.

Great end of summer deals on Simms summer gear and much more at Wolf Creek Angler. 

The State of the MO 2022

7,000 Trout Per Mile – source Jason Mullen FWP Fisheries Biologist

Montana Fish, Wildlife and Parks Fisheries Biologist Jason Mullen delivered the annual State of the Missouri presentation last Wednesday in Helena in a meeting held at Montana Wild Education Center by Pat Barnes Missouri River Trout Unlimited and while there were some encouraging revelations, it sounds like the challenges posed by drought conditions will persist in 2022.

First the good news.

6,611 RAINBOW TROUT PER MILE.

Mullen reported the second highest number of rainbow trout over 10” long on record in the Craig section (Wolf Creek Bridge to Craig), more than doubling estimates from surveys from the previous two years. This number is second only to the 2012 estimate of 7,068.

Coupled with the brown trout estimate of 362 fish per mile which is down considerably from the long term average of 560 but still within normal parameters, that’s a trout count of nearly 7000 fish per mile in the Craig stretch. The Missouri fishery continues to amaze.

Drilling down into the data the good news continues. 2021 surveys saw an estimate of 1400 rainbows per mile in the 20 plus inch size class, a number we would expect to see drop off this season, though with the abundance of small fish in the 6” – 7” class we saw in 2020, it’s very possible the big fish trend will continue through 2022. 2021 surveys revealed good numbers of rainbows in the 9” – 10” range which should continue to bode well for big fish numbers on the MO.

The brown trout saw big numbers in the 6” – 8” range, very few in the 9” – 16” range and upward trends in the 17” – 24” range with each of those last size classes numbering somewhere in the neighborhood of 50 fish per mile. We would expect to see a lot of those fish in the 10” – 16” size range this season, hopefully with a stable population of big browns in the mix.

This is all great news on the fishery front in the Craig stretch and truly amazing when you consider the pressure on the fishery which ranked second only to the Madison in 2019, the last year for which we have data, with 154,628 angler days. It’s worth noting that this angler use figure is down from the previous two which were 170,736 and 183,479 in 2017 and 2015 respectively. It’s a lot of use no matter how you cut it but the downward trend is surprising and one I’d expect will change once the 2021 numbers are in which will include last year’s Pandemic Migration to Montana. Trip related expenses for anglers on the Missouri totaled over $60 Million in revenue in 2019 which makes the MO and fishing in Montana in general, a MAMMOTH portion of the state’s economy.

Now the not so good news.

2021 saw extremely low flows and high water temps and with not having had much of a winter the reality is that absent a very wet spring, we’re likely in for more of the same in 2022.

The Missouri saw Hoot Owl restrictions in July of 2021, the first time this has happened in over 20 years, when low flows and water temps in the 70 degree range coupled with high angling pressure caused FWP to announce the closure.

We had essentially self-imposed our own Hoot Owl restrictions for guide trips a couple of weeks prior and stopped booking new trips altogether for the summer season at that same time. It’s unfortunate, but we’re readying ourselves for similar conditions in 2022 and we’re prepared to do the same things again. Canyon Ferry is currently 68 percent full so we’ve got a ways to go and while snowpack is currently in the 70 – 80 percent range, most probable flow conditions project flows to be essentially right where there at, in the 3,000 CFS range, all season long. 

We would love to see massive amounts of precipitation over these next couple of months to bring things back into shape but as always, our main concern is doing what we need to do to take care of the resource and if this means taking a financial hit we’re ready to do so.

Pray for rain!

 

Hoot Owl Comes to the MO


As drought conditions persist in the region, FWP announced additional waterbody closures and restrictions yesterday including Hoot Owl Restrictions on the Missouri from Holter Dam to Cascade.

Almost immediately following the announcement the pushback began from some citing that the criteria had not yet been met for Hoot Owl Restrictions referring to FWP’s water temperature threshold which states that max water temp of 73 degrees for three consecutive days trigger implementation of Hoot Owl Restrictions. Water temps however are not the only criteria triggering restrictions.

From FWP…

Flow below Holter Dam is near the 10th percentile for the daily average on record and the temperatures recorded throughout the section have exceeded 70 degrees Fahrenheit. Although flow and temperature are not exceeding established criteria for restrictions, continued forecast high temperatures coupled with high angling pressure could lead to excessive fish mortality, leading FWP to implement the restrictions.

Having made the decision to suspend new trip bookings for the remainder of the summer a couple of weeks ago and having voluntarily implemented Hoot Owl fishing hours on our existing guide trips, we are in full support of FWP for implementing restrictions on the MO and elsewhere.

We definitely understand the inconvenience of these restrictions and we sympathize with all of those who have traveled to Montana to fish this summer but we’re trying our best to focus on the big picture rather than the immediate impact of lost fishing opportunities for our guests and what has already amounted to thousands of dollars in lost revenue for our business.

This is about the preservation of the future of the fishery here on the Missouri and throughout the state of Montana. And while the effectiveness of these restrictions in limiting angler-induced fish mortality can be debated, our position is that doing something is better than doing nothing and if limiting our hours on the water helps even a little bit then it’s not that big of a sacrifice when you consider what’s at stake.

We hope for cooler conditions and we’d love to see restrictions lifted prior to September but in the meantime we’d like to share these tips for HOT WEATHER FISHING.

This past June for SW Montana ranked in the top 5 driest and hottest for SW Montana. Correspondingly, water temperatures are also greater than normal. Angling for trout under these warmer-than-usual conditions, fish become more impacted by catch-and-release, which increases the amount of time it takes them to recover and the chance that they will not survive.

Warmer water contains less oxygen than colder water. As temperature rises and dissolved oxygen decreases, fish begin to experience stress. These stresses occur well before the water temperature reaches lethal limits. For example, rainbow trout can survive in temperatures up to and exceeding 77°F (24°C), but stop growing at 73°F (23° C). Therefore, a fish, one which is already oxygen stressed while positioned carefully in current that minimizes its energy use, will be dramatically more stressed after being hooked and played to the net. In fact, in many cases, a fish otherwise properly handled and released under thermally-stressful conditions may be likely to not survive.

The following are best practices for angling during warmer weather:

• Carry a thermometer and stop fishing as water temperatures approach 68 degrees F.

• Use larger tippet sizes to decrease the amount of time playing a fish.

• Use a net.

• Get the fish as quickly as possible to the net.

• Use a dehooking tool to quickly remove the hook.

• Keep the fish in the water.

• Forego the grip-and-grin photo opportunities.


We don’t want to come off preachy, we’re just trying to do right by the resource. We’re not saying you shouldn’t fish, we just ask that you abide by thw restrictions the state has implemented in an effort to protect a fragile resource.

We’re open at 6 AM daily so you can get your day off to an early start and we’re happy to get you set up with what’s working and send you off to the spots where you are likely to have the most success.

Thank you for doing your part to take care of our precious resource.

And Suddenly it was JULY

It’s hard to believe but June is officially in the books. Summer is in full swing and flying by. The BLUR has commenced!

We’re in the midst of our busiest three weeks of the year with all of our rental boats out daily and scores of guide trips starting earlier and earlier to beat this scorching summer heat.

Our day starts on the early side of 4 AM in order to get all of the boats where they need to be prior to opening the shop and it’s not uncommon to end our day in the dark hauling boats and getting them cleaned up for the next day’s launch.

We’re currently under a Heat Advisory through 9 PM on Friday. Temps are bumping up against 100 degrees daily with minimal chance of precipitation. Night time temps are comfortable in the 60’s but even so, with the flows being what they are, water temps are on the rise. We’re currently looking at flows of 3280 CFS and water temps holding right around 62 degrees. Keep in mind these readings come from just below the dam. The lower stretches are likely considerably warmer, something to keep in mind when choosing where to fish.

Low flows and high temps have already resulted in Hoot Owl Closures on several rivers in the region and with no cool down in sight we are likely in for more. The Missouri River water temps in the upper section are still in good shape, nowhere near the 73 degree threshold which prompts those closures after three consecutive days however the lower river, as already stated, is considerably warmer and may very well be subject to Hoot Owl Closures at some point in the not so distant future.

With the heat persisting we are responding by trying to get our trips out as early as possible and also giving our clients the option of doing half days if preferred. If you’re on your own please consider an early start and early off as the fishing tends to slow considerably during the afternoon hours. Should Hoot Owl Restrictions be placed on the Missouri we will shift all full day trip start times to 6 AM or earlier.

PMD’s and Caddis are your dry fly staples with Tricos knocking on the door. PMD’s in the mornings, Caddis in the evenings and the nymph forms of both effective anytime. Dry fly fishing has been good enough to keep the DFO’s busy and there are plenty of big fish looking up, willing to take a well-presented offering. We’re seeing plenty of fish up daily, perhaps not the mega pods of old but definitely enough to make a day of it.

Nymphing has been solid everywhere with the best action coming from the shallow, faster water. Split Case PMD’s and Crack Back PMD’s have been the go-to nymphs but there are all kinds of PMD and Caddis patterns they’ll eat right now. Stop in on your way to the water and we’ll get you set up with the right bugs for the right times. That way if you end up having a tough time out there you’ll at least be able to rest assured it’s not your bug selection.

The shop is officially open at 7 AM daily but we’re usually underway by 6:30 AM if not before, especially as we move those trip start times up.

Make us your first stop on the way to the MO for fishing licenses, ice, vehicle shuttles, sunscreen, Simms SolarFlex sun shirts, Fishpond Eddy River and Low Country Sun Hats, Smith and Suncloud sunglasses, our signature NO PRESSURE NO ATTITUDE FRIENDLY SERVICE and advice rooted in DECADES of Fly Fishing and Customer Service Experience and the biggest and best selection of Missouri River bugs ever assembled under one roof in Wolf Creek Montana.

We’ve established a great following over these past 7 seasons but we still hear it enough from those who darken our door to continue to proclaim that we are the best Missouri River Fly Shop you never knew was here.
