Bear Gulch

If you enjoy streamer fishing, now begins the time that Box Canyon is great, especially during a stormy day like today.  Another such location is “The Tubs” where Henry’s Lake Outlet and Big Springs Outlet combine above Mack’s Inn.  This time of year fish move downstream from the river in the Flat Ranch to the deep cover in these holes. There are several other locations along the river where streamers are very effective now. From Warm River to Ashton is particularly good. So is the river just below Ashton Dam. Want to pitch streamer patterns in a tranquil location free of boats?  Try the river at Bear Gulch, just above Mesa Falls Park, and below Coffee Pot Rapids as well as “The Tubs.”

If you enjoy the BWO emergence anywhere along the river, do not overlook using soft hackle patterns (partridge and olive , size 14) for emerger imitations.

The lower river offers a variety in dry fly fishing, and the turn in the weather predicted for next week can only help with respect to active fish.   Along the lower river terrestrial insects still inhabit banks in good numbers. BWO and  mahogany duns numbers will increase with the change in weather.  The evening caddis emergence continues. Streamer fishing is improving, and get even better with unsettled weather.  Tricos, a few remaining PMDs, and increasing BWOs make for good fishing in the Last Chance-Harriman section. Box Canyon offers good nymphing, with streamer fishing sure to pick up.  The river in the Flat Ranch is pretty much done for the season.

Streamer fishing on lower river is picking up as browns begin spawning migrations. Choose low light conditions for best chances of encountering one, and have both somber and bright patterns in that fly box. BWOs and mahoganies are also emerging, so mid-day dry fly fishing can be good. Consider that wind will blow concentrations of these mayflies to the down-wind side of the river, so position yourself accordingly when presenting dun patterns.

Not much change here with AM trico swarms, daytime terrestrial insect activity, and evening caddis activity. This applies to just about the entire river.   As browns begin to migrate in the lower river streamer fishing will be increasingly effective, especially during low light conditions.  The lower river is cooling so look for tiny BWOs to become active enough to interest trout.

Terrestrial insect season is going on up and down the river. Exceptions include AM trico mating-spinner falls and evening caddis activity.  PMD activity is greatly diminished and speckled duns are important only on slow river reaches such as the Flat Ranch and Harriman State Park.  When cloudy days arrive streamer fishing will be more effective during mid-day rather than just around first light and twilight.  Tiny BWO activity on the lower river is several days away.

As with our small streams report, anywhere you try the Henry’s Fork be sure to have grasshopper patterns in that fly box these days. Other events attract trout including evening caddis hatches on most of the river, spinner falls, and speckled dun emergences on the slower portions of the river.  But nothing is as totally attractive to trout this time of year as hoppers.    Look out for recreational floaters going through Box Canyon, especially during weekends. Anyone seen any honey ants other than around the Harriman section?

Anywhere on the river cloudy skies and high relative humidity will improve your mid-day fishing success.  Patterns for spinner falls, caddis (life cycle patterns during evening hours) streamers, and terrestrial insects can be most effective during these times of day and under these atmospheric conditions. On the upper river the arrival of honey ants will boost trout’s desire to come to the surface any time.

Bear Gulch

Presenting terrestrial insect patterns is fruitful in the AM or PM whether you fish the upper or lower river.   Other than that, the upper river (Last Chance-Harriman, Coffee Pot-Tubs (watch out for recreational boaters) has AM and PM spinner falls.  Be also on the lookout for recreational boaters in Box Canyon where nymphing and presenting caddis life cycle patters  in the evening brings good results. Cardiac Canyon is nearly deserted by anglers, so consider taking those terrestrial insect patterns to such as the Hatchery Ford and Bear Gulch accesses.

The best and most consistent fishing in the Last Chance-Harriman section of the river is through presenting terrestrial insect patterns.  The big mayfly hatches are gone for the year although speckled duns and smaller PMDs are present. Rusty spinner patterns will work early and late in the day, but when flying ants arrive in good numbers fish will notice, and some of the best summertime fishing arrives.  For the warming lower river use rusty spinner patterns in the AM, and terrestrial insect  and caddis life cycle and streamer patterns in the evening.

Brown Drakes (evenings) and flavs (afternoons) have begun emerging in the Last Chance-Harriman stretch of the river. I drove by the Last Chance Rest Stop  about 6:30 PM yesterday. Saw only one fly-fisher trying the river just downstream (???).  Maybe most of those were below in the Wood Road 16 area judging  from the the campers, etc. seen way downstream on passing over the Osborne Bridge.
