I took my client Lloyd down to Pit 3 for an evening session tonight.  Things started slow, but everything changed when I switched to a size 8 rubberlegs nymph.  That got their attention!  Lloyd landed 4 and lost about 6 in less than an hour of fishing.  We hooked fish from 12-17", all fat rainbows.  There was quite a hatch right at dusk: a mix of mayflies, craneflies, and caddisflies.
