Culvert capacities have been determined to be inadequate; however,
flooding due to inadequate culvert size is minor. All three road
crossings would be overtopped to a shallow depth during a IOO-year flood
event.

The IOO-year flood depth averages about 2.5 feet above the thalweg
(the channel bottom). Velocity in the channel averages about 6.5 feet
per second, with higher velocities at the upstream end of the analyzed
creek.
