pond was originally constructed in the 1930s. we installed a stop~log water control outlet pipe (C) in '95 when we built a 1 acre marsh below the pond dam.
over the last 6~7 years, beavers have invaided our pond and have built multiple dens (1,2,3,4) on the west dike. the dike has collapsed and isn't holding water.
we are planning to cut a hole in the dam and remove the original outlet pipe (A,B). if you look closely at the pond side of the pipe (A), you will see a beaver hole beneath the 12" pipe. the drain side of the pipe (B) has a corresponding hole as well.
i'm planning to rent a track hoe for the weekend in march to drain the pond and remove the original pipe.
should i remove the beaver dens on the west dike with the track hoe or wait until the ponds dry in the summer? by mid~summer, we'll have a dozer guy come into rebuild the west dike and build the west marsh.
the pic is a "well~like" structure that i don't know what or how it was used. any idears?
finally, we may be building the lower marsh as well this summer. i'd like to rebuild the dam in such a way that it drains most (if not all) runoff around the east side and into a "collection ditch) to fill the lower marsh.
