Erosion Information
Total Erosion at Crossing: 3.3734 tons/year
Extent of Erosion: Severe
Erosion is occurring and corrective actions can be installed to address the problem.
Notes: Cement barrier severely undercut because of confined flow and extremely high velocities eroding away at the bank.

Summary Information
Fish Passability 0
Fish Passage is an area of concern for this site.
Extremely high velocities create absolutely no fish passage, lots of erosion, and has created a very large scour pool downstream.
A future visit to this site is recommended. everything needs to be replaced. Culverts are old and rusty, water is confined to a fraction of the width that it should be, fish passage is nearly impossible, cement barrier at the crossing is undercut and it deteriorating.
These non-native species were observerd at this site: Reed Canarygrass, Leafy Spurge, Spotted Knapweed, Bladder Campion
