Now that we’ve reached Aug. 1, all the fishing irregularities that come with this time of year are upon us. And this year, with low water conditions and high air temperatures, the fishing is a bit tougher than normal. I can’t say the fishing is bad but you have to work at it to make things happen.
SILVER CREEK—Water levels have improved a bit. Water temperatures at 64 degrees may be optimal for fish metabolism, yet they are higher than the normal 53-55 degrees. Hatches are strong but inconsistent. Beatis and Trico spinners are the main players but many feel that Trico, which started earlier than normal, may be on its slide. As a general rule, fly size is (#22) is vastly important. If you are off one size, you are going to end up only watching fish eat a lot. Dave’s CDC Trico Spinner #22, Mason Quill Beatis Spinner #22, Rusty Spinner #22 and Beatis Sparkle Dun #22 will do the job. Hopper fishing in the afternoon can be productive but a little wind would be more then helpful.
BIG WOOD RIVER—I’m certainly finding fish but things aren’t easy, especially if you’re looking for fish of size. Take a deep breath because this scenario may be with us a while. The river is flowing at a low but reasonable rate (170 cfs) and the best opportunities are morning and evening. Surface activity can be had using Para Adams #16-18, Dun Gulper Specials #16-18 and Rusty CDC Spinners #18. Nymphing with Pheasant Tail and Flashback Pheasant Tails #14-16, Prince Nymphs #14 and Copper John’s #16 are finding the better fish but the big boys and girls are still tough to find. I’m also not as yet doing back-flips over the Hopper fishing. My fingers are crossed.
BIG LOST RIVER DRAINAGE—The upper river (East Fork) has been very inconsistent. A few fishermen are finding some success. Most are finding either an empty nest or fish far in between. I’ll leave it up to you to make the call. The lower river below the reservoir is exceptional. The flows have come up a bit (200 cfs) but nothing to disrupt the fishing. Trico has started and the fishing is sensational in the morning using Dave’s Trico #18-20 and Para Adams #20. Prince Nymphs #10-12, San Juan Worms #12 and Copper John’s #12-14 are always deadly throughout the day.
WARM SPRINGS/TRAIL CREEK—Both are very low and the fish have become skittish. They are somewhat concentrated in deeper water runs that do exist. Para Adams #16 and Bead Head Prince #16 work nicely. You need to be extra careful on your approach and presentation. They can see and hear you coming.
PENNY LAKE/LAKE CREEK/GAVER’S LAGOON (HAYSPUR)—All are heavily fortified with fish and since they have nowhere to go, all are susceptible to hook and line. Various baits and flies will do the job.
SOUTH FORK OF THE BOISE—Not much change here. Flows remain the same and it depends on where you cast a line as to what success you will have. Pink Alberts, some Cicadas (waning) and Hoppers are your “go-to” flies. Wooly Buggers are finding some large fish, too.
