Additional Comments
There was no water in the stream at the time of the visit, except a little above the inlet in a small pond and some inside the culvert, which was not moving at all. It was difficult to determine the inlet and outlet because of low streamflow. Cow pastures closely obrdered the stream on the west side of the road.
