March 2015 Fishing Report

March has started off with a fresh coating of snow adding to our snowpack for the season.  Speaking of snowpack, we are sitting at 83% of normal with our reservoirs holding at 80% of capacity for the season.    Our mild winter continues with temps reaching near 60 degrees this coming weekend.  The lower sections of the Henry's fork have been fishing extremely well over the last month.  The boat ramps have stayed relatively free of snow allowing us access to float Chester Dam down to St. Anthony.  As Tyler Treece and I found out this last Sunday  the fishing continues to be great!  The rainbows are just starting to show signs of spawning, so remember to keep your eyes open for their spawning beds or otherwise known as "Redds".    The flows out of the box canyon are low enough to wade the entirety of the canyon. Big springs is another winter favorite in Island Park. Getting into big springs can be just as much fun as fishing! Check out a video we created last year during early spring called Cabin Fever for a little winter stoke! For those of you on foot, renting a pair of snowshoes from the Shop makes getting to the water a much easier task. Additionally, for a more adrenaline fueled adventure, our next door neighbors have snowmobiles to rent. Call Island Park Adventures at (208)-558-7581 or visit their webiste for more information. 


















During the months of December and January it isn’t practical to post a current fishing report. That doesn’t mean there isn’t plenty of opportunity to find good fly fishing if the weather is favorable. Conditions won’t change much through the cold winter months so this fishing report is designed to share our expectations for this time of year. We will be posting a fishing report once a month through the winter months of January, February and March to focus on winter midge fishing opportunities over the next few months.  


Upper Henry’s Fork

Fishing can be very good throughout the winter months in the stretch from the confluence of Henry’s Lake Outlet below Big Springs downstream to Highway 20 at Mack’s Inn. The problem is access. This area gets a lot of snow closing the road to Big Springs. The only access is by snowmobile, snow shoes or cross country skis. Several Island Park businesses rent snowmobiles by the day. You can also rent cross country skis or snow shoes at Henry’s Fork Anglers. Unless you are an accomplished Nordic skier we recommend snow shoes. The water temperature in this stretch is relatively constant due to the proximity to Big Springs. Midge fishing can be very good. Streamers and nymphs are also productive if you can’t find fish rising.  

Box Canyon

The water temperature below the Island Park Dam stays constant during the winter months providing good fishing opportunities at any day of the year. Nymphs provide the best fishing. Our favorites include red, olive or brown Zebra Nymphs, Tungsten Flashback Pheasant Tail and smaller black or brown rubberlegs. Leech and streamer patterns can also produce but you need to swing them or strip with a very slow retrieve. Access can be a big problem due to deep snow. You always have the option of renting a snowmobile or snow shoes. We also provide guiding opportunities here as long as we can get the boat in and back out at Last Chance.

Last Chance / Harriman Park

The water from the boundary of the Harriman Park downstream to Pinehaven is closed to fishing until June 15, 2015. However, the stretch through Last Chance is open year round. It isn’t uncommon to see nice trout feeding on midges on any day of the season. Water temperature can have a major effect on fishing even though it is only 3 miles below the dam. Keep an eye on the weather and if it is not too cold you can find great dry fly fishing. You might need a pair of snow shoes even though the river is only a short distance from the highway. Parking can also be an issue but you are welcome to park in our parking lot or several other businesses close by.

Wood Road #16 – Pinehaven

Fishing is closed from the south boundary of the Harriman East State Park downstream to Riverside Campground until the opening of general fishing season on May 23, 2015.

Canyon Water

Access to the Henry’s Fork canyon from Riverside downstream to the confluence at Warm River is not available unless you have a snowmobile. Even then, hiking down to the water in deep snow is very hazardous and not recommended. There is a good snowmobile trail from Bear Gulch up to Mesa Falls that provides awesome winter scenery and is worth the trip even if you don’t fish.


Warm River to Ashton

This stretch can provide great fishing throughout the winter months. However, the water temperature can fluctuate greatly with the weather. Sometimes it gets choked with slush ice. I recommend staying close to the confluence with Warm River if you are wade fishing. Warm River is a spring creek and the water temperature doesn’t fluctuate too much below the confluence. Use the same patterns recommended for Box Canyon. It is only possible to float this water if the boating accesses are not closed from snow. Normally these accesses are not available until at least mid-February.

Ashton Dam to St Anthony

The tailwater section from the Ashton Dam downstream to the Vernon Bridge is closed for fishing until May 23, 2015. However, with the mild winter we are having the boat ramps have stayed relatively free of snow allowing access to float the lower sections of the Fork.  Egg patterns, leechs and midges have been very productive while floating Chester Dam to Fun Farm.   Keep an eye out for rising trout from 1pm to 4pm if the temps rise above freezing.

St Anthony to Confluence

With lower snow levels has made the wade fishing accessible, with the warmer than normal weather we have been experiencing the river has stayed relatively ice free.  The fishing has started to pick back up in this stretch of the river.  Look at the video we filmed last March.

Henry’s Fork Tributaries

Fall River is a freestone stream and as such it normally gets completely choked with ice. Even if the water is open it is normally full of slush ice during the winter months. Don’t write it off, however, because I’ve had some fantastic fishing as soon as the water shapes up, usually in mid-February. Warm River can produce good dry fly fishing upstream from the Highway 47 Bridge. Remember the water below the bridge is closed to fishing year round. Fishing the Buffalo is only an option near Pond’s Lodge.

Madison River

The fishing season on the Madison is a little complex so we highly recommend you check carefully with the Montana fishing regulations for more detailed information. The section from Hegben Lake Dam to Quake Lake is open year round. The stretch from the Quake Lake Outlet to McAtee Bridge is closed to fishing from March 1 until the third Saturday in May. The Madison is open to fishing year round from McAtee Bridge downstream to the Ennis Bridge. The fishing season is closed to fishing from March 1 until the third Saturday in May from the Ennis Bridge downstream to Ennis Lake. Fishing can be very good in this section between the lakes. We like Zebra Nymphs, Tungsten Pheasant Tail, Skinny Nelson and a variety of other small bead head nymphs. You can also find success by swinging a stream through the deeper runs. Access can be tough because of snow.  Also check in with Kelly Galluops Slide Inn fly shop in Montana click link below.

Teton River

The fishing on the Teton has slowed down over the last couple of weeks, however fish can be found sipping midges in the slack water areas.  Midge patterns with long leaders and proper presentation is the name of the game here to catch winter trout in the upper basin area of the Teton river near Driggs.  Also don't forget about  the lower river sections from the Old Dam site downstream to the confluence can produce some exciting results this time of year.  Try fishing streamers on a dead drift as well as slow jigging movements to entice lethargic trout to take your fly.    

South Fork of the Snake

There are a number of very good options on the South Fork during the winter months. For wading anglers we recommend you concentrate your efforts near the Heise Bridge or downstream at Twin Bridges. The upper river is also good from the Palisades Dam downstream to the Spring Creek Bridge above the South Fork Lodge. Access can be difficult but if you can find good water you’re likely to find good fishing with nymphs or streamers. Midge fishing can also be very productive. Best fishing occurs on mild overcast days. The South Fork can also be impacted by cold temperatures resulting in flowing slush ice but there are usually some good days when the weather is right in December and January. Another good option that is often overlooked is the Big Feeder Canal or Dry Bed. This large irrigation ditch holds enough water during the winter months to provide quality fishing.  Also check in with Worldcast Anglers for current winter river conditions for the South Fork, click link below.

Area Lakes

Unless you like to fish through the ice wait until the ice goes out in Late April or May. Though the ice fisherman have been reporting good numbers of cutthroat being caught on jigs. Reminder Henry's Lake is closed to fishing starting January 2, 2015

Yellowstone National Park

CLOSED FOR SEASON - Will reopen Saturday of Memorial Day weekend 2015
