I have watched them my whole life here on Ranch, when I was a kid the creek was solid white sand, what would run foot deep in big storms,as time went by it stopped raining like 50’s and 60’s grass moved in and streams got foot or two wide. Beaver’s moved in in 70’s and started building dams, ponds started filling up , perch, bass and cats were caught on every cast, ducks were on every pond, river grass are in every bottom now for cattle to eat in drought summers when no body else has any grass. I used to try and control numbers but when I did it seemed to hurt the water flow. The place is a paradise with all the deer , turkeys, duck, quail, I don’t think, I know what good Beavers do for cattle and wildlife.
