Would it not be better to do this as the stream dries, as opposed to now when levels will fluctuate?
Are you working from the outside edges in, towards center?
How wide will base vs height be? A lot of folks underestimate the base width of a beaver dam.
Super cool project! Good luck!!
Now, that rare map is giving researchers some new insight into just how busy beavers can be. A new survey shows that many of the dams and ponds that Morgan saw nearly 150 years ago are still there—testament to the resilience of the rodents and their ability to maintain structures over many generations.

Modern conventional dam building techniques are designed to be durable on a 50+ year time frame without lots of ongoing construction.

All I have are well-drained fields and hillsides with deep ravines that need big rock to begin to stabilize them. Oh, and a creek that can move 80 foot white pines right through my property in major floods, and tumble 2-ton rocks if they are not well bedded.
I don't think it will be an issue on your small watershed, but my impression is that many of the sticks in a beaver dam are laid parallel with the water flow, which would resist high flow better than if they were crossways to the flow.

A lot of people cry when they cut onions. The trick is not to form an emotional bond. This tiny ad told me:
