The South Fork of the Boise River closes up march 31, so get after it while you can! It will reopen on Memorial Day Weekend. Warmer temperatures will make Blue Wings Olives and Midges come out a little bit more, so keep an eye out for them. As of today, subsurface is still your best bet, but not for long. Make sure and take plenty of nymph & midge patterns, beatis emergers, leech & streamer patterns (olive, brown, black, earthy tones).
