Now that Memorial weekend has passed, we can begin positioning ourselves for an early season. That means lower than normal water levels and also early hatch appearance. Currently, most all of our waters are clear enough to fish but wading on some is still a bit dicey. With not much runoff left to come down, I suspect that this week we be the last of high water conditions we will see for the rest of the season. Let's take a quick look:
SILVER CREEK—Until weather and wind set in, the Creek has fished very well. Hatches were strong and came with enough variety that surface activity has been very good. Somewhat spotty, the Pale Morning Duns nevertheless provided enough feeding situations that a Para PMD #16-18 and a Crippled PMD #16 readily took fish. Beatis and Callibeatis were also seen and a Beatis Emerger #18-20, a Para Lt. Olive Dun #18-20 and both a Partridge Spinner #16 and Partridge Thorax Dun #16 worked well. Large Ant and Beatle #12-14 imitations were deadly when the wind blows. The fishing will get tougher but these hatches, even if they are sporadic, should be the mainstay for the weeks to come. If the weather stays warm as predicted, I seriously would be on the lookout for the Brown Drakes, appearing in the evening hours by the weekend. Standard Brown Drake Paraduns and Spinners #10-12 should do the trick if the big Mayfly shows itself.
BIG WOOD RIVER—It is clear enough to fish but with water levels rising over the weekend, wading the river is not going to be the friendliest of tasks. Therefore, if you can get to back eddies, back channels or any areas where water velocity is diminished, good fishing can be found. Hatches will be of non-importance but it wouldn't stop me from throwing a Stimulator #8-10 on the water just to see what might materialize. Big nymphs such as Prince#8-10, Copper Johns #10 and Golden Stonefly Nymphs #8 (all weighted) should bring success and big Black, Olive and Brown Wooly Buggers #6-8, stripped along seam lines, should find some fish as well. By next week, we should have a better picture of just how the Wood will unfold for the year but I can certainly say that things will be earlier than normal.
WARM SPRINGS/TRAIL CREEK—Warm Springs is low, clear and fishable. Parachute Adams #12-16, Yellow Stimulators #12-14, Bead Head Prince #14 and Flashback Pheasant Tails #12 should find a few fish. This was the case with Trail Creek but over the weekend, it turned slightly off-color. Since it is always the last one to clear, I’d give it a week for better conditions.
BIG LOST DRAINAGE—The Upper Lost River is a tough one to call. Water levels are down meaning that the East Fork is probably clear and fishable. But until I have a firm report, I can't bring myself to recommend it. It's still early and mid-month might be a better time frame. The lower river will be clear and fishable but at 500 cfs, wading will be tough. Best results will come from nymphing using Prince Nymphs #8-10, San Juan Worms #10, Griddle Bugs #10 and Cranefly Larva patterns #8. Because of irrigation, this will be the story of the lower river for the next couple of months.
SOUTH FORK OF THE BOISE—Still running at 1600cfs which means floating rather than wading the river will bring your best results.
