Henry’s Fork

Henry’s Fork 3-23-19

Flow below Ashton Dam is a bit higher ( 1400 cfs) than normal (1100 cfs) with the river in good shape. Fishing is good if such as rubber legs and streamers are presented.  No BWOs to speak of yet, but plenty of midges.  So life cycle patterns of these might get you some top water action.

We have some information on lower river fishing success from Ashton Dam downstream to the Fun Farm Bridge.  The river is somewhat higher ( 1350 cfs) than normal (1060 cfs) according to the gage below Ashton Dam. Walk-in wade fishing gets one to most of the river, but float fishing is a bit limited because of conditions at some boat ramp sites.  Streamer fishing is good.  Midges are abundant making for a bit of top water fishing.  BWO activity is not important yet, but as we warm up will become increasing to attract fish during afternoons especially on overcast days.

Seems like what is going on for fishing the South Fork applies to the lower Henry’s Fork. Afternoon BWO activity, caddis later in the afternoon, and mostly presenting streamers to migrating browns.  BWO activity rules the roost at the Last Chance-Harriman stretch, while streamer fishing in Box Canyon and The Tubs is the order of the day.  If you plan on fishing the upper river, watch the weather.

Notice that what happens on the lower Henry’s Fork (Warm River to St. Anthony) is similar to what is going on this time of year on the South Fork.  On both rivers flow is dropping to base level. BWOs, mahogany duns, and midges provide the best dry fly fishing.  Streamer presentation gains in effectiveness as the fall season advances through November as brown trout make spawning runs.  If switching to streamers is to your liking, the  best places on the upper river this time of year include Box Canyon, the base and the top of Coffee Pot Rapids, and The Tubs above Mack’s Inn.

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.
