Spring Yellowstone River Floats: Our float season on the Yellowstone begins in roughly mid March, when longer days and warmer water make guided trips possible.  The early season, from now until runoff dirties the river in early May, is something of a sleeper bet, and offers uncrowded conditions, usually comfortable weather as long as you remember a spare layer and a raincoat, excellent streamer and nymph fishing, Blue-winged Olive mayflies and midges for match the hatch dry fly action, and in late April or early May, the epic Mother's Day Caddis hatch.  Depending on river flows and what you'd like to do, in the spring we either float a long stretch and bypass some less productive stretches or fish a short float very thoroughly, getting out to fish the best sections on foot, so waders are required.

        Spring is a good time of year for those seeking to escape the crowds, especially if you have a couple days on which a float might work, in case cold and snow or an early surge of spring runoff forces us to reschedule.  It is also a good bet if you want to fish "meat" for big fish, since the larger trout are aggressive for streamers and large nymphs after a tough winter.  All spring floats are eligible for our shoulder season rate.

        Summer Yellowstone River Floats: 90% of the Yellowstone's float pressure occurs in the summer, and if you're making your first visit to the region or love attractor and terrestrial dry fly fishing, this is when you should come, too. 

        Immediately after runoff recedes in late June or early July, the trout go on a subsurface feeding binge, seeking out Golden Stonefly and Salmonfly nymphs.  The famed emergence of these bird-sized bugs is one of the most anticipated events of the angling year, and is a time when some of the largest trout in the river will rise to dry flies.  As the Salmonflies and Golden Stones taper off, many species of caddis and small stoneflies begin hatching, making it possible for our clients to fish dry flies almost exclusively for much of the summer. 

        For the dry fly angler, midsummer is Nirvana.  As the grass begins to turn gold, natural insect hatches begin to fade and the trout turn increasingly towards terrestrial food sources: grasshoppers.  While the wind can make casting a challenge, few things beat the explosive rise of a rainbow or cutthroat, or better yet, the gentle sip of a 20-inch brown taking a two-inch grasshopper imitation like a smaller trout would take a half-inch mayfly.  The weather is usually quite comfortable and most of the time we leave the waders at home and wet wade getting in and out of the boat.  Since flows are high and the trout concentrate tight to the banks (and the bushes), we tend to float 10-12 miles every day and do almost all our fishing from the boat.

        Beginning sometime in August, flows through Yankee Jim Canyon drop enough to make drift boat fishing reasonable.  As one of the few outfitters to run this section of the river regularly in drift boats, we'd love to introduce you to this beautiful, rugged section of river where the trout love taking dries especially well.  Book your Yankee Jim float early.  Only high-side drift boats have enough freeboard to make the run safely, and Head Guide Walter Wiese is our only guide with a high-side boat.

        As noted above, summer is the peak of dry fly fishing on our floats and is the most popular time to float the river, both for clients to our guide service and others.  It also offers the most consistent fishing in general, though chances for gigantic fish probably aren't as good as in spring and fall.  Conditions are usually consistent, though the occasional summer thunderstorm can make some stretches unfishable for a day or two.  Except in Yankee Jim Canyon it's hard to avoid competition from other boats and some wading anglers, but the Yellowstone only gets truly "crowded" on rare summer days and during the Salmon Fly hatch, and your back cast is more likely to hit a whitewater boat or a pleasure floater than another guided drift boat.

        All summer trips fall under our standard rates, and we encourage you to book as early as possible for late July and early August dates, especially if you have a large group, wish to request a specific guide, or are booking several days in a row.

"I fish the Yellowstone every year and my favorite stretch is Yankee Jim Canyon.  The scenery alone is worthy of the float -the huge boulders and deep pools create a distinctly unique floating experience.   Without a doubt, I catch more fish in Jim Yankee Canyon than any other piece of water.  The fish just don't see much traffic through the canyon.  We have more multiple hook-ups on that stretch than any I know of."

        Fall Yellowstone River Floats: Sometime between August 20 and Labor Day, changes begin.  Instead of banging the banks, we often run a bit farther out and fish broader riffles and other structure.  The trout start getting suspicious about the larger, normal grasshopper patterns and attractor dries, and start wanting smaller flies and often stranger ones --pink grasshoppers and purple mayfly imitations in 2009, for example. 

        At some point in this timeframe comes the first taste of cold weather, with clouds spitting drizzle and daytime highs in the high 40s or low 50s.  With this weather come the first fall Gray Baetis (Fall Blue-winged Olive) mayflies, which typically bring large numbers of selectively rising trout to the surface.  As fall progresses, hatches of this insect become more and more consistent, so that by late September we're fishing Baetis imitations part of almost every day.  At times they are joined by the larger Epeorus (Western Cahill) or even Green Drakes.  By late October the Blue-winged Olives begin to grow somewhat less common, but they continue along with midges until our guide season ends in mid-November, long after most guide boats are off the river.

        Starting in late September or early October the hardcore streamer bite comes back after languishing somewhat through the summer.  With the brown trout and some rainbows preparing to spawn, and the rest of the rainbows and the cutthroats fattening up for the tough winter, ripping big flies out of the boat or swinging them slowly through the longer pools can produce some exceptional fish.  The largest trout ever taken on a Parks' Fly Shop guide trip came at this time of year, on a streamer.  The fishing for fall run browns gets steadily better through October, though fewer and fewer anglers are around to target them.

        As in the spring, we either float a long stretch in the fall and skip some less productive sections or fish a short section of river very thoroughly, including fishing most of the productive riffle corners on foot.  In the autumns of wet years it is more likely we'll float a long stretch, while in dry years lower flow rates usually mean it's better to float a short run rather than push through a long stretch.  Yankee Jim Canyon usually remains fishable until sometime between mid-September and the tenth of October, and by the autumnal equinox the number of guide boats and general fishing traffic on the river have dropped off to levels only slightly higher than in the spring, making the fall another great time to float the Yellowstone if you like solitude.  There's also the added bonus of cottonwoods in their autumn color, with the backdrop of the first snows on the mountains.

        We remain quite heavily booked for Yellowstone floats through September, so it's best to book September trips as early as you can.  Things thin out through October, meaning that we can usually set you up on short notice even if you have a large party requiring multiple boats.  Trips until mid-October fall under our normal rates, while those after October 15 fall under shoulder season rates.
