Channel construction continues

The banks of the Mill River are taking shape as meander bends are constructed using coconut fiber soil lifts. These banks will provide structure to the channel until plants take hold. The bottom layer will become part of the channel bottom with gravel and cobbles, and the top two layers will degrade over time as plants grow.

Large wood and root wads from the trees that were once on the dam will later be placed in the channel to add habitat structure and a place for fish to hide and turtles to bask. The floodplain surrounding the channel will be a lower elevation and will be able to store floodwater at high flows.
