Preferred sites for damming will be in areas where the dam will flood a large flat area and there are plenty of desirable woody plants for food in the vicinity.
Streams that are more than two feet deep or have strong currents are not generally dammed. Beavers often situate their dams where there are constrictions in the stream flow natural or manmade.
This is why beavers have a strong propensity to dam culverts. For relatively little work they can create a large dam and pond. Each beaver colony will usually establish one large pond which where they will build their lodge. In addition to this primary pond other smaller dams up and downstream are usually built to create smaller ponds. These smaller ponds permit safe travel for the beaver as it seeks out new food supplies.
The average beaver colony will dam a half-mile length of a small stream. Beavers are monogamous and mate for life. They do not breed until they are two to three years old. In Massachusetts the female becomes pregnant during the winter and gives birth in May or June.. Beavers have one litter of 1 — 6 kits per year. The availability of food appears to affect the size of the litter. Only the adult female breeds. The average number of beavers in an established family is typically six or seven beavers.
We have seen as few as one and as many as thirteen. Once a beaver reaches the age of two they will usually leave the colony to find a mate and establish a colony of their own.

But not in the way you might think. Not only are these ponds deep enough to deter land animals , but they also allow beavers to dig underwater entrances into the lodge.
This means that if danger emerges, they can safely exit or escape through these tunnels. Lodges in the UK can be a whole 10m across, requiring dams around m in width. From how long dams last for, to what food beavers eat inside their lodges, you can find a river bank of answers below. Not even on Fridays. After finding food, beavers have a clever way of creating a shortcut back home.
Having located a particularly scrumptious willow tree, for instance, a beaver may dig out a small canal through the riverbank that leads straight back to their dam.
