The flyfishing here in Nevada County has been a day to day affair.  We chased a day old report of topwater action for smallmouth bass on Scott’s Flat Reservoir and found nothing but small fish the next night.  We did have the lake to ourselves.  Dock is out of the water, but a launch is easy with 4×4.  It’s the same on the Lower Yuba tailwater.  Still very cool water, but caddis hatches may come off one evening and not the next.  If they do its very late. Have a second rod rigged so you don’t have to tie fly on in the dark.  Both my partner and I broke fish off on 4x.  Some big rainbows are in the river now as salmon start to come in.  Flows are being lowered.
