Summary Information
Fish Passability 0.5
Erosion is an area of concern for this site.
Considerable erosion of sandy loam around inlet of culvert. While the flow was nearly stagnant in dry conditions it appears that after heavy precipitation this culvert passes a significant amount of water.
A future visit to this site is recommended. Install erosion control measures.
