Description
A long island divides the channel. Silt from the reservoir spills into the river and settles in the flat stretches of the first half of the run. The silt provides footing for trees and brush. Here the trees and brush grow completely across the river, though in a long, right to left diagonal. The river has small openings at each end of the island. The upstream opening is bigger and leads to a more gradual drop. The downstream opening is very small and has a steeper more junky drop.
