Looking at the beaver dam from under the bridge.
The Bestiary, or Book of Beasts, written between 1220 and 1250, describes the beaver as fallows:
“There is an animal called the beaver, which is quite tame, whose testicles are excellent as medicine. The naturalists say of it that when it realizes that hunters are pursuing it, it bites off its testicles and throws them down in front of the hunters, and thus takes flight and escapes. If it so happens that another hunter follows it, it stands up on its hind legs and shows its sexual organs. When the second hunter sees that it has no testicles, he goes away. …The beaver (castor) is so called because it castrates itself.”†
The Castor canadensi in our clear water ditch seem to have given up castrating themselves, as they have the balls to keep building dams after Conservancy staff tear the beavers’ dams out. So far the beavers have built their third dam in the same place after the first two were torn out over the past couple months.

Beaver dam from under the bridge on the bank of the clearwater ditch, The debris from the previous dams the Conservancy tore out is piled up on the other side of the ditch.
A little elm tree the beavers have been gnawing on.
Piles of debris from previous dams with the latest dam rebuilt in the same place as the other dams.
