The bank is almost 90 degrees and erodes easily during high water events. This bank has no vegetation and erodes quickly depositing large amounts of sediment into the creek. While the bank erodes the creek also grows wider this lowers flow and makes the stream shallower and raises the temperature.

One of the ways to fix a 90 degree bank is to build a fascine (bundles of logs placed along the shore to reinforce it). This process starts by sloping the bank so that high water exerts less force on the bank. After that a brush mat is laid down, this forces the water to go over through the brush to get to the bank. Finally, plants and vegetation are planted on the bank so the soil is secured.
