When I suggest looking at the flows of your chosen water, I don’t mean just before you go fish. That would give you info for the day, but if you follow daily, you will learn the ever-changing “personality” of a river. When you combine changing flows, with monitoring the water temp, you can learn to perceive the moods of fish, as well as where to find then, and when to go fish. Above, is a daily swing of temperature. Drops at night, peaks after noon. Scroll down from the USGS flows and click on temp.The dramatic swing everyday, is what I see as sharks teeth. The physics of low water, is it’s affected more easily by outside conditions, whether heat or cold. The higher the flows, the milder the temperature swing. Trout are well aware of these influencers. Bugs seem to notice the flows and the temps too…. If you care to raise your game, the way I want to raise my game….you will learn what I just shared, by heart. It took me twenty years to figure out that this was a concept, and another thirty years to get a handle on it. When you have it down, then add predicting how the weather will affect the fishing formula, just for fun. The recreational fisher goes fishing and hopes to get lucky. A good guide/advanced fisher has learned luck has little to do with it…..and that paying attention is everything. As much as I enjoy getting someone started in fly fishing, finishing a fisher who desires the connection to water I’ve hinted at here, gives me even more joy. Give a shout if that appeals to you.
