August is here, and despite the low water conditions, fishing has remained steady and productive. Fishing small flys and light tippet points may not make everyone happy. But given the conditions, it’s what we have to deal with. I don’t see much change in the weeks to come so I’ll make this report short and sweet.
SILVER CREEK—The Creek has been productive but what and how much you will encounter is a matter of your fishing location. It varies as to where you put in. Trico and Beatis are still your primary morning hatches but the great Trico spinner falls of old can be spotty. Clouds of the bug appear but in many cases, only a few fall to the water. It seems to be a bit better in the upper end of the Preserve. Regardless, a Dave’s Trico Spinner #22, a Mason Quill Beatis Spinner#22 and a Sparkle Dun Beatis are doing the job. PMD spinners have been heavy in the upper sections but I would suspect this hatch will be disappearing after this week. A Gray/Yellow No Hackle #16-18 is deadly. Hopper fishing in the afternoon has been adequate but at the same time, a little spotty. Some afternoon winds would help.
BIG WOOD RIVER—Although we’ve now reached wintertime flow levels (160 cfs), fishing has been much better and a bit easier than expected. Trico in the morning and Beatis into the afternoon are the principal hatches and the fish are on them but you need to be careful. Because of the conditions, the fish will slip down to the tails and long, calm sections of runs to feed. As a result, they can be spooky so you need to cautious in both wading and casting. Fly size is now getting more critical. Para Adams #18-20, Dave’s Trico #18 and a Para BWO #18-20 will move fish but 6x tippets are becoming a must. Hoppers have been so-so but you can still find some interested big fish. Nymphing with Prince Nymph #14, Pheasant Tails #14-16 and Olive Soft Hackles #14-16 will also find some nice fish as well.
WARM SPRINGS/TRAIL CREEK—Both are very low in flows and the small fish can be skittish. Para Adams #16 and Bead Head Prince Nymph #16 will find fish, although they will probably be small ones.
BIG LOST RIVER DRAINAGE—Upper waters are very low but some nice fishing has been reported on the lower, main stem of the Lost. Standard, Wood River patterns only larger in size will do the job. The lower river has now passed into prime flow conditions (380 cfs) and the fishing is great. Trico in the morning is heavy and Crane Flys in the afternoon have been better than average. Randomly fishing Para Adams #14 in the afternoon can be worthwhile. Prince Nymphs #10-12 and Copper Johns #12 are must carries.
PENNY LAKE/LAKE CREEK/GAVER’S LAGOON (HAYSPUR)—Always supplemented with fish and various baits and flies will work.
SOUTH FORK OF THE BOISE—Still running at mid-season levels making wading a little dicey. Beatis and Pink Alberts are found in the afternoon and heavy Caddis in the evening. From this point forward, Hopper fishing is a must do.
