Beavers have been living in the canal and Lake Carnegie for a long time, and I had been wondering why they hadn't made it up Mountain Brook to Mountain Lakes and Pettoranello Gardens. Now that they have, I'd expect more will come. My hope would be that some way could be found to accommodate the beavers while keeping the pond level stable and any valuable trees protected. There are devices that allow water through dams without the beavers being aware. In my opinion, the beavers would do Pettoranello Gardens at least one favor by thinning out its thick stands of alder along the water's edge. If the beaver's additions to the dam obstructed storm flow, then a spillway for heavy runoff could be dug somewhere along the bank. The pond already has a bypass upstream of it for storm surges.
