Terrestrials and Tricos are swarming the banks of the MissourI!

Herds of elk and some of the biggest trout of the year were spotted last week at the Missouri River Ranch. The warmer weather has added new challenges and opportunities to the Mighty Mo. While the weeds forming in the river can make for the occasional frustrating drift, those same weeds produce great habitat for stealthy brown trout that feed just off the weed line. Getting out a little earlier in the day (our boats have been leaving the ranch around 7a.m.) and trusting your guide's knowledge of the river have been paramount in converting the warm Montana days into floats of a lifetime...which happened more than once this last week. While the size of the fish is not as important as the size of the adventure and memories, we had multiple guests catch the biggest trout of their lives over the course of their recent stays. This warmer weather has also pushed the elk herds down into some of the meadows around the ranch. On a scenic drive before dinner, we had one group of guests count over 100 elk in one field, so stay on the lookout for all the other wildlife the Missouri River Valley has to offer. Water temperatures are measuring around the mid-60's at Wolf Creek and flows are remaining consistent at around 3500CFS.
Timing is everything! Terrestrials, Tricos, and Caddis are all still in play, but picking the right imitation at the right time is crucial. Tricos can come off in massive swarms during the morning and evening but may not be what trout are keying in on throughout the day. The nuance on fly selection can be tricking, but Caddis and Trico patterns have worked best when bugs are present on the water. Transition to your Hopper or terrestrial flies when searching through the middle of the day. Midge Clusters, Cornfed Caddis, and Rusty Spinners are still good standbys when the hatch is on. Switch to your tried and true Chubbie Chernobyl or Water Walker to search out fish lingering along the edges during the heat of the day. Remember with terrestrial patterns, trout are used to seeing these meals fall from along the riverbank or accumulated along weed lines, so focus on placing your fly as close as you can to the appropriate structure to elicit that big eat.
Depth and current is dictating the subsurface eats on the Missouri. It seems like the fish on the Mo are either feasting on big meals like a Zirdle or smaller nymphs like Green Machine or Zebra Midge. Anglers have found more success with a Zirdle or Zonker in faster moving water or even with a little swing to their presentation, and noticeably more eats from the smaller nymphs in slower moving water. Play around with your approach and also your drift. While a "drag-free drift" is the ticket in most scenarios, let your Zirdle swing through the end of your drift. This added motion has been just enough to convince some of the biggest fish on the river to commit.
When fish become more lazy in the warmer water, they can move to looking for a few big meals a day rather than trying to eat thousands of smaller bugs. This is where the streamers can fill that niche. Remember that throwing streamers this time of year may not produce huge number days, but the fish that are willing to commit to that big meal are generally our larger fish in the system. Keep at them with Thin Mints and Gamechangers. Play your fly close to weed lines and banks and try to have the fly moving as soon as it hits the water. Don't shy away from running a double Zirdle setup and use stack mends and strips to keep the fly moving through the current. This technique is tougher but has produced some incredible trout for your efforts.
Drop us a line, and we'll see you soon at the ranch! This is sure to be an unbelievable season on the Missouri.
