Summary Information
Fish Passability 0
Erosion is an area of concern for this site.
Significant erosion is occuring at this site. Although it is a small stream and may be dry parts of the year, it is certainly a fish passage barrier as well.
A future visit to this site is recommended. To replace culvert, or to install measures to mitigate future erosion problems.
