Bob, The tree does not bother me. This being my first pond I have no experience with regards to pond maintenance and up keep. With the knowledge I have gained from this forum and seemingly endless expenses I believe I have the true money pit. What a learning curve! After reading the prior posts with regards to trees on the dam I was just attempting to alleviate future problems. Might be a little late for that. I am wondering if this is one for the don't kick the sleeping dog routine.
Meadowlark, With regards to the roots I fully understand that issue. I had to abandon the out fall pipe for the pond. When I sent a camera up the pipe to investigate,I was suprised to see a root in a seperated section of pipe. That pipe was 18' down and 5' over from the willow.
Decisions, Decisions, seems like a loser all the way around.
