Summary Information
Fish Passability 0.5
Erosion is an area of concern for this site. Large unvegetated embankments appear to be contributing substantial material to Vaughn Creek.
A future visit to this site is recommended. Recommend establishing vegetation on embankments. Also, culvert probably somewhat undersized and a larger structure would be more appropriate.
