Rather than cut the plywood, why not add a thin layer of foam where you want the millpond, keeping it below the nearby scenery (build-up the scenery if you have to), then add a dam at the downstream end of the pond. Use an even thinner layer of foam (or plaster over screen) to build-up the river banks downstream from the dam. It wouldn't have to be any higher than a layer of corrugated cardboard, as you can make the banks more distinct when you add trees and groundcover. The plywood between the two banks is the riverbed. The river can be level all the way to the stone culvert - the rising roadbed behind it will make it appear to be going downhill, and you can exaggerate this even more by building-up the banks as they get closer to the culvert.
