South Fork, July 31st, 2024

Water flow out of Palisades Dam is now just under 9000 cfs and has been dropped step-wise from around 12000 cfs on July 19th .  Flow reductions such as this; 3000 cfs in eleven days, give salmonids a chance to adjust resulting in much less impact on salmonid activity whereas an abrupt drop of this much would have a noticeable negative impact.  Caddis fly, remnant golden stone, and PMD activities make for top water activity which can be spotty in places. Nevertheless the South Fork currently provides the best stream fishing in the area.

Henry’s Fork, July 31st, 2024

Do trout a favor by considering limiting fishing from first light until 2 PM because of rising water temperatures. This especially applies to where the river runs through open areas such as Last Chance through Harriman and Ashton Dam to Chester Dam.  Bare, rocky canyon areas, like Warm River to Ashton, heat up more quickly and hold heat longer that forested canyons (i.e. Cardiac) areas through which a stream runs   As summer advances, ant and grasshopper patterns will become increasingly effective for taking trout presented along all shorelines. In Box Canyon, hopper-dropper, two nymph rigs, rubber leg and fly rod jig patterns fished deep can bring action.

Yellowstone National Park, July 31st, 2024

High summer temperatures are now impacting Yellowstone Park streams. Because water temperatures have been measured at 68 Deg. F. or greater in more park streams, further “hoot owl” type closures have been applied. Thus fishing is prohibited from 2 PM – midnight on the Snake River from the South Entrance upstream to Forest Creek, the Gardner River from Osprey Falls downstream to the north boundary, and the Yellowstone River from Tower  Junction downstream to the Park north boundary.  These restrictions do not apply to lakes open to fishing in the Park.

Southwest Montana, July 31st, 2024

Gulpers on Hebgen Lake’s Madison Arm are currently the big fly fishing attraction in south western Montana. Maybe not to the same extent as on Hebgen, other lakes have gulper action. The south end of Ennis Lake, bays on Hidden Lake, and the north end of Elk Lake are examples. These are much less attended by fly fishers than Hebgen’s famed gulper activity, so a visit to one would be much less hectic..

Until the wind comes up, Mackay Reservoir has been good fishing lately through using indicators with midge pupa patterns at the taking depth. Normal drawdown for downstream irrigation is going on, so water level seems to be stable.

Small Streams, July 31st, 2024

Canyon reaches of all streams will have highest afternoon water temperatures, among these are Fall, Teton and Blackfoot Rivers and lower Bitch Creek. So fish them early in the day and beware of rattle snakes residing above the high water mark. 

Flow out of Mackay Dam into Big Lost River is around 450 cfs making wading the river below a bit if a chore. Caddis, PMDs and western green drakes are emerging, but with the somewhat high flows, San Juan worm and such patterns sunk low in the water column are best bets for action.

Southwest Montana, July 27th, 2024

Big news here is that gulpers are going good during mornings on the Madison Arm with some on the South Fork Arm of Hebgen Lake. The trout will be working on these until around noon or until the wind comes up. So get ready with your callibaetis life cycle patterns, then switch to leech patterns of choice later or when wind gets going.

Henry’s Fork, July 27th, 2024

Summer doldrums are impacting the lower river, while cooler AMs and thunder shower potential help in keeping fishing success reasonable on the upper river. Also helping are growing stream side terrestrial insect populations (especially ants!). Algae is beginning to show in Island Park Reservoir and could impact water quality in the out flow. Water temps are generally such that dissolved oxygen concentrations are above the five mg per liter stress level for trout. Nevertheless consider minimizing fishing after three or four PM because this threshold could be approached and recovery of a caught and played trout impacted.

South Fork, July 27th, 2024

Although flow is lower than average for this date, water conditions could not be better. Top water fishing is due mostly to PMD and caddis activity in and around riffles up & down the river. No significant pink albert or mutant golden stone numbers yet.

Palisades Dam boat ramp and Palisades Creek boat ramp and campground are undergoing a pavement project meant to improve access and visitor experience. Palisades Dam site will be closed starting Monday, July 29, until approximately Friday, Aug 9, while that portion is completed and the pavement cures. Palisades Creek boat ramp and campsite will remain open during this time to allow continued boat access to the upper section of river. Once the Palisades Dam site is completed and usable, construction will begin at the Palisades Creek boat ramp and campground, and it will be closed for public access until completed. Closure dates for the Palisades Creek site have not yet been finalized. This story will be updated when more information is available on the opening and closing of both locations.
