Fishing has been quite good this past week. But things began changing over the weekend, making the catching part much more challenging. The hot air temperatures are affecting insect activity and when it will occur. If the weather forecast is correct and with the full moon upon us, look for more of the same. Translation: Bankers hours are over. If you plan to have another cup of coffee in the morning, things might be over by the time you finish. More problematic conditions and results will happen midday.
SILVER CREEK—I can’t say things have been hot on the Creek. Water levels are still low and have actually dropped from last week. That’s bothersome. Hatches are very inconsistent and the best time of day for some decent results is early morning. Beatis spinners and Trico are your “go to” hatches. Mason Quill Beatis Spinner #22, Rusty Spinner #22, Dave’s or CDC Trico Spinner #22 will take fish depending on what is happening in front of you. Afternoons have been tough (heat) but some good results with Blue Damselfly imitations will find a few big fish. PMDs have been iffy but it always worth having some fly patterns in your box.
BIG WOOD RIVER—Hatch activity has been strong and fishing very good. Things got tougher over the weekend. Mid-mornings into the afternoons are slow, early mornings and evenings are in. So you should fish accordingly. Water levels and flows still have some steam to them but that should be quickly changing. Lingering hatches of Green Drake and Western Quill Gordons are still around and may get us through the weekend, but probably not much longer. Mason Green Drake #12, Colorado Green Drake #12, Olive and Regular Parachute Hares Ear #12-14 and Para Adams #14-16 should move some fish. Yellow Stimulator #12-16 has been effective. Because of Cream Dun spinners (E. deceptivus) in the morning, Para PMD’s #16-18 will work as well. Nymphing with Flashback Pheasant Tails #12-14 are also effective but you have to work at it and be patient.
WARM SPRINGS/TRAIL CREEK—Both are at wonderful levels to fish effectively. I actually say rising feeding off of morning Western Quill spinners and a Para Hares Ear and Adams #14-16 did the job. Bead Head Prince Nymphs #14-16 can also find some surprisingly larger fish.
BIG LOST RIVER DRAINAGE—Fishing in the Copper Basin area is reported to be very good. Much the same fly patterns used on the Wood should do the job. With lower than normal water flows and the great hatches of small Yellow Stoneflys and some Pale Morning Duns, fishing on the Lower Lost has been sensational. Hopefully we can get through the weekend but these hatches do have a short life span. Yellow Stimi’s #12 and Para PMD’s and Adams #16 will work but it is also that time where Cranefly activity in the afternoon can produce some amazing fishing. Prince Nymphs, Copper Johns and San Juan Worms #12 are always a must.
PENNY LAKE/LAKE CREEK/GAVER’S LAGOON (HAYSPUR)—All were heavily planted over the 4th and should have an ample supply of fish going into the weekend. Various baits and flies should do the trick.
SOUTH FORK OF THE BOISE—Still flowing at 1600 cfs. Floating the river with some marginal wading is still the name of the game. Salmon Flys, Cicadas and Caddis in the early morning and evenings are your principal target hatches with Pink Albert’s right around the corner.
