I had the chance to fish the Lower Stanislaus a couple days ago and thought I'd file a report. The gauge it Ripon read about 550cfs, pretty typical for February I believe and I fished mostly up around the dam.
First of all, it was 70 degrees. It felt like summer, in a weird way like I've spent so many summer days fishing tailwaters or small mountain streams hiking and sweating, slathered in sunscreen. But it's not summer, it's freaking February! So yeah, it was kind of surreal for a Northwest kid. Anyway, I hooked a few fish in the am on top with #18-20 Parachute Adams and midge patterns. I found a big foam swirl with a pod of fish going off. Problem was it was across 500+ cfs of deep, fast water with little backcast room and little line control. So lengthy, wild casting ensued. But I managed to hook a few bows in the 12" range.
Later I lost a gagger after it ran me under a log and down a riffle, hooked on a tiny Zebra Midge on 5x. It was pretty awesome though, sight casting to a fish that big, watching him swim up and chomp down.
The rest of the fish I hooked were on small mayflies and midges. They didn't seem to want the worm at all but maybe it just wasn't a wormy day. I ran into a guy that asked me, "what size hooks" I was using. It was kind of comical but he was nice enough. Anyway, long story short, I hooked probably a dozen fish in t shirt weather in February on a pretty canyon stream. Does it get any better? I doubt it.
