Additional Comments
The inlet, outlet, and/or in pipe may be crushed or plugged and the culvert may be rusted through, but the culvert was completely underwater so we couldn't tell. Also there is no riffle as the stream becomes a marsh, and the channel is blocked by grass.

Erosion is an area of concern for this site.
Yes, there is a large scour pool, and the culverts are completely underwater-the area is flooded.
A future visit to this site is recommended. To see what the water level is at other times of the year and to see if the culverts are often underwater.
