In my experience, those gauges are tough to use to predict fishability, especially considering how fast the tribs can rise and fall. A 400% spike might mean a blowout, or possibly a temporary flow that last for a few hours. The only places where I use such data are dam outflows, where the gauge gives you an accurate idea of how wide open a given dam may be. Primarily, I use the USGS charts for relative measurements. "I was up there a few days ago when measurements were at X level. They're now at Y level, so conditions will change accordingly." rather than absolutes, "I see that level is at X feet with a Y cfs flow, this will mean Z fishing conditions." Make any sense?
