Erosion is an area of concern for this site.
STRUCTURE SEVERELY ERODED AT BOTH HEADWALLS. HEADWALLS ARE JUST CRUMBLING DIRT BEING HELD BY FAILING GUARD RAILS
A future visit to this site is recommended. THIS IS SERIOUSLY A WASHOUT CONCERN WITH A NICE COBBLE RIFFLE IMMEDIATELY DOWNSTREAM. SEE PHOTOS!
