Yes another beancounter here. Any tax questions out there? "Is my pond construction cost a tax write off?" ..... MAYBE

Here's another question. My pond site sits in the middle of a mature woods that will need to be cleared. The surrounding woods is mainly soft maple. It has been logged pretty hard and the remaining trees max out at around 24" diameter. I still expect a lot of leaves making their way into the pond. How quickly will this become a problem in a 1 acre pond? Is there anything that I can do to prevent negative consequences from the leaves?
