We have found it best to anchor up the boat near the underwater breaks, or along the current seams that form, then cast and mend like normal to let the current or wind do it's thing. Once we've covered the water we move. Basically I just break the river down by observation then fish each area thoroughly. The bank anglers do get a good long drift down the snake below the confluence, but we leave that to them, and they get fish. Many people just run the bobber in the current behind the boat until they get fish. We got several while the anchored/still bobber got one matching our silver hen.
