a Check Dam is a type of erosion control construction used to help rehabilitate eroded trails. A check dam is constructed by placing a rot resistant log across the trail in such a way that any dirt washed down from above will accumulated behind the log eventually making a step in the trail. When one check dam has filled up a new one is added slightly uphill to catch the dirt from above and to make the next step in the trail. Rot resistant logs are often logs from trees such as black locust.
