Hi everyone first post I have 8 acres in the Catskills,NY. 1-2 of it is bog .when the beavers move in it holds 4" of water. My best idea to date is purchase an excavator pull off the top soil then dig to a decent depth . This area is fed from a 5 acre lake across the street and a very small trickle which even in the summer flows. Any input would be appreciated as I love to learn from those with experience
