Fog On The Swift And An Old Fly Works Well
The Swift has been bouncing between 45 cfs and 125 cfs for weeks now. I can't talk about what's happening above RT 9 but the fishing below RT 9 has been better with the lower flow. There are a few reasons for this. A higher flow may move the bows around while the lower flow will concentrate them. But there is another reason for this and it's the Summertime fog that wraps up the river on high flows. First, the fog is created by the mix of cold air near the cold water and the humid Summer air above. At 45cfs there is little mixing of the air because the low flow has less cooling effect. Ramp up the flow to 125cfs (a lot more cold water) and you'll have those blankets of fog that can last all day. I see far fewer mayflies when a heavy fog is on the water, period!!! That means fewer rising trout!! All of this is moot when we have a clear, low humidity day. There will very little fog. The "Old Fly" - backcast to my post of 1/12/09. The old Millers Bivisible, a big bushy concoction, DID raise two bows through a heavy morning fog on the Swift. I think the trout could see it!! Ken
