Thank you for the reply. I am thinking about a sediment pond as one of the remedies. So far all the talks between my neighbor and I have been good. He has said he will "make it right". I can only hope that he is sincere. My concern though is the erosion is going to continue for some time (maybe a year) until they have replanted all the disturbed areas. So my question is what, if any, detrimental effects (besides more sediment in my pond) can I expect from this suspended sediment if it remains that way for 6 months to a year. I may be overly concerned and I hope I am but I believe I am already seeing more filamentous algae than I had before. I am new to this pond business so I just don't know what to expect. If it is just going to be muddy water then that is ok but if it is going to be excessive algae growth and or other things I would like to take a pro active approach. Thanks again
