The beavers have already begun to rebuild, but there are still questions and concerns that will have to be answered in the days to come.
How long will it take the pond to recover? Were their damming efforts taking place during the breach and now that the pond is drained, will they continue to dam or will they abandon their efforts?
The pond leveler in the upper pond is functioning perfectly and thanks to heavy rains this week, it is feeding the lower pond water that it would not be getting otherwise. Also, the fact that we had the pond leveler installed was, is, and will be added protection against breach of the main dam.
However, the water is flowing through the culvert pipes at a rate that would normally attract beavers to the outflow culvert cage installed this spring. Will they concentrate efforts on the breached dam at the far end? Will they try damming the culvert?
We certainly won't be needing another pond leveler for a while, but we may have to modify the outflow protection, if the beavers try to dam it. I guess we are going to have to watch and leave it to the beavers.
The only immediate action that is required has been taken. I left a message with mosquito control and am awaiting a call back. A few years ago, I had contacted them to see if we had anything to be concerned about. At that time, they said the pond itself was no problem, but they put us on their watch list and check us during normal inspections.
