Beula Lake

Looking for almost certain still water fishing success? Beula Lake right now is a great location to try. Packing a flotation devise the 2.5 miles into Beula from the Ashton-Flagg Ranch road is the best way to achieve this, but so will fishing at the inlet do the same. Get to the inlet by walking a couple of hundred yards along to south shore to the southeast corner of the lake. There is plenty of room on the small inlet delta here for a few fly fishers to present damsel fly and speckled dun life cycle patterns or even traditional dry patterns (like parachute adams) to foraging Yellowstone cutthroat trout, the only salmonid or game fish in the lake.

Fishing Reports, Small Streams

Almost all small streams are now open to fishing (Teton River drainage river drainage streams are rounding into fishing shape). Many, however, have restrictions. For example, the Blackfoot River drainage above the Blackfoot River Reservoir requires barbless hooks, no bait, and return of all cutthroat trout to water from which they are caught. Many waters require no harvest of cutthroat trout. Refer to Idaho Department off Fish and Game Fishing Rules and Regulations to determine which streams require return of cutthroat trout to waters from which they are caught.

Hatching Damsels

With hot weather coming up, expect that trout in many of our irrigation reservoirs will be moving to deep waters, and that shallower waters there and elsewhere will feature a growing amount of aquatic vegetation. Such will discourage cast and retrieve fly fishing and make early and late in the day top water fishing best. Finding the “taking depth” will be a best tactic. Do so by suspending such as a midge pupa pattern at different depths under an indicator. Speckled dun mayfly and damselfly activity can be present on many of our still waters and will be a “saving grace” for top water fly fishing enthusiasts. Damsel flies emerge mainly around aquatic vegetation mats and because of their numbers fish key on them.That suggests that their life cycle patterns are useful. Look for damsels having peak hatching activity during wind free and mild weather days.

Fishing Reports, South Fork

The South Fork has arrived as a primary fly fishing location, and its waters are where they should be for this time of the season with respect to clarity, flow amount, and temperature. That means giant, golden and isoperla stone flies, green drake and PMD mayfly hatches advancing up the river and caddis activity prevailing during late afternoons. So the South Fork will have a surge in fly fishing interest compared to that currently happening on the Henry’s Fork because of peaking South Fork aquatic insect activity and warming of Henry’s Fork waters. Whether you wade at select locations or fish from a boat, expect that great weather will also bring out recreation boaters in addition to action-seeking fly fishers.

Be tolerant of boat inspection actions, and understand that reasons for such are to protect the agricultural and sport fishing industries.

Cool Water Prevails in the Tubs

Presently, flavs and PMDs make up the major mayfly activity throughout the river. Notice that the size of PMDs is diminishing to make dun, emerger and spinner patterns reduced to the 18-22 range best to simulate them. Brown drakes are hatching from upstream slower waters but are well past their peak in numbers. Water quality is good nearly throughout the river except below St. Anthony where temps up to 70 deg. F. are present. Speaking of warm water; with hot weather coming next week, the river below Ashton Dam will warm to the point that daytime hours will limit fish activity making early and late in the day the times for good fishing. This change will eventually happen on the upper river. Consider that not only warming air but also bright sunny times contribute to making this change. The positive aspect of hot sunny days is that they will bring on the terrestrial insects throughout the river. Check your stock of terrestrial insect patterns!

Mayflies still reign supreme along the entire river. Drakes are diminishing, but flavs and PMDs in emergers through spinners, so bring life cycle patterns. Brown drakes are still around in certain locations during evenings, Hot dry days make for difficult fishing success, because water temperature gets elevated ( 70 Deg. F.is becoming common). Best times are during overcast or even before and right after thunder showers happen. Do you know why? Simply because the air is most humid meaning adult aquatic insects do not dehydrate as quickly.

One thing about hot, dry weather, it brings on terrestrial insects. So survey your ant, beetle and hopper patterns. You are going to need them soon!

Well Fed Rainbow Trout

it is time to leave the Firehole River’s trout population alone because of its water being warmed to levels where dissolved oxygen is low enough to inhibit their to survive being caught and released.

There are plenty of alternatives for the fly fisher who prefers top water fishing.

The nearby Madison and Gibbon Rivers offer PMD and caddis hatches that are attracting trout to feed. PMD and yellow sally hatches are going on in Fall River Basin streams. Want a real challenge in Yellowstone Park top water fishing? Try slowly drifting your favorite green drake pattern through Duck Creek in its meadow. Green and brown drakes are present but very sparse.Trout being there 24/7, know when they appear. The utmost of skill, stealth and concentration are required to fool the hosted brown and rainbow trout which range well into trophy sizes.

At Clark Hill Overlook

What the fly fishing world has been waiting for is happening, The salmon flies have begun appearing on the South Fork. They are present in good numbers around the Lorenzo area but moving upstream in smaller numbers as far as Byington. With warmer water and great weather, they will likely be in the canyon this weekend. Even a few green drakes have been spotted along the lower river, so make your favorite life cycle patterns for them available. River flow has settled down to usual for this time of the year, and Palisades Reservoir is full. There will be occasional boosts in flow depending on irrigation demands but the time is coming when caddisflies, mayflies and stoneflies will be available for feeding trout at any given time, and it will up to the flyfisher to determine which they are keying on. It makes for a fun and challenging game!

Rainey Creek

Big news here is that all South Fork spawning tributaries below Palisades Dam open to fishing on Monday ( July 1st). The same applies to the entire Blackfoot River drainage above the Blackfoot River Reservoir. Closing to fishing on all these waters until July first is done to protect spawning cutthroat trout.

Twentyfour Mile Reservoir

Twentyfour Mile Reservoir is the last we look at in the series of four southeast Idaho reservoirs IDF&G is managing as trophy rainbow trout fisheries. It is the most remote of the of these reservoirs. A summary of studies performed by IDF&G fisheries biologists is below.

At Twentyfour Mile Reservoir our crew captured one rainbow trout, three hybrids and 18 Yellowstone cutthroat trout. The rainbow trout was 19 inches long while the hybrids averaged 10.3 inches. The Yellowstone cutthroat trout averaged 14.1 inches long. This species’ average length is similar to that of the 2016 gillnetting survey when the average length of Yellowstone cutthroat trout was 14.7 inches. About 14% of the population sampled was legally harvestable, exceeding 20 inches in length. Anglers venturing to Twentyfour Mile Reservoir should also keep in mind that no motors are allowed on this small water body. 

Crystal Springs Pond will be drawn down in order to complete adjacent county road repairs.

Fly Tying Classes

Fly tying classes are offered mainly during Winter. Fly tying demonstrations, featuring tiers from around the area and beyond are held every Saturday morning (November through March) and are free and open to anyone to watch.
