Erosion and Sediment
In the latter scenario, the sediment that is washed out will likely be carried downstream. The photographs from trib 7 shown below are not isolated examples; the dynamics of erosion portrayed are symptomatic of the Potash Brook watershed as impervious surfaces ratios increase with suburban development and continue to stress the watershed. The effect of sediment loading places a significant burden on both the downstream receiving waters and on the fragile ecosystem of Lake Champlain.

As the tributaries flood and filled with wash-out debris, the creek bed is forced from the natural channel. Cutting a new channel (see below) will dislodge more sediment.
