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!
