Missouri River August Fly Fishing Forecast

Missouri River August Fly Fishing Forecast

Missouri River August Weather

Hot. Super hot. Abnormally hot and windy and Smokey due to the local fires. The daily average air temps hover around 95F. Lows come in in the hi 60’sF.F. Average rainfall for the month is 1.57inches. Third behind May and June. June being the wettest. So afternoon thunderstorms will keep you guessing with rain totals enough to remind you to keep the ranger nearby in August.

Be ready for anything. Cooler mornings have you donning your puffball shedding it mid morning for a HH logo’d SIMMS sun shirt. Headhunters is your local sun gear store. More selection, styles, and better pricing than the rest! Stop in for a full selection of gloves, Buff’s,  sun shirts, SUNBUM sunscreen and more!

Missouri River Flows and Water Temps

Flows are hovering around 3000cfs. And hopefully not go below 3000cfs. Federally mandated low is 2800cfs. That is damn low.. That is the projected summer Missouri River Flows. Water temps will top out at 70F. Then will fall gently throughout the month. Not too much lower at the completion of August, but we should not see them rise above where they currently are.

Weeds? Yes. Always have weeds here on the Mo int he late summer and early fall. This year is no different. They are developing now and will continue to grow toward the surface. Let’s hope we do not have too much of that river goo this season. Call us for the updates you need.

Last year the weeds on a scale of 1 to 10, 10 being god-awful…they registered a 5. This summer? Not terrible in the upper reaches. As you head downstream they gather in big floating islands. We will only know after the event. Again, Mother Nature is typically very difficult to predict.

Missouri River August Hatches

Trico’s continue through the month well into September. Strong hatches in late July as the bugs seemed to gain speed and intensity. Great Trico Missouri River spinner falls daily @ 915am. Fish them until noon or 1pm.

PMD’s Gone.

Caddis flies can get you through the mornings. Toss one blind nd see what happens.  Get on the caddis train and catch those night fish! Downwinged patterns as well as spent caddis need to be in your possession. How about one of our favorites the Translucent Pupa and the Translucent Emerger. Come find your caddis fly love on the Mo in August. They will be around through the end of the year. Do not go out there with out the caddis fly in your front pocket.

10 Wednesday Thoughts from Squeeky's Vapid Head

Terrestrials. August is the month for ants and hoppers. Fish the am Trico, the Buzzball!  Then switch to the ant for a blind fishing afternoon all the way home. Or your favorite hopper pattern. Try one you can see!

August Nymphing Forecast

Pretty good. The big fly will spend some time on the upper end of your nymph rig. Crayfish and worms and ZIrdles and junk like that. Big flies up top and small flies on the bottom.

You can go deep in the morning and short until 2pm when the Hoot-Owl dictates we look for a shady spot and nap. Or you can rig it up without split and 2′ from bobber to fly right out of the gate. Choose the depth you want to fish and get after it.

Be creative. You can also rig a dry-dropper outfit. A big fluffy floater, an Adams, or a caddis fly up top, or an ant and attach one of the killer tungsten beaded patterns like the Two-Bit Hooker or similar and have a ball fishing the Missouri River this August.


Good to great until the weeds inundate the river. Or not. Lots of folks out swinging. Soft hackles mostly. Then we can dream the weeds away and get ready for Swing Season. It is on the horizon in late September thru May 2021! Oh, it’s coming. Look to Headhunters for all of the new ’20-’21 spey gear that will be filling the shop! Flies? We got the swingers covered here. Softies, streamers, and traditional swing patterns for all your Trout Spey needs. Demo rods too!
