There is an active beaver dam blocking the upstream flow of a culvert which Armstrong Brook passes under. Lots of woody debris. The beaver dam is also causing a pool. Rip-rap rocks around the culvert are present. The culvert is 2.2 meters in diameter concrete but also reinforced with metal. Algae was noted in the water course and the water was cloudy and grey.
