Site Observations:

  1. Constriction ratio red

Comments: Three pipe arches with pipes 2 and 3 in the stream channel. Pipe 1 is located outside of the channel and dry with several feet of gravel and cobble embeddness. Two additional smaller pipes were located to the far left upstream side as your looking downstream well outside of the ordinary high water mark.
