Digging out old ponds

I have begun an adventure on my property.  There are a series of 4 ponds down a south facing slope on our property.  They are all in terrible condition after at least 30-40 years of neglect. Side note, I purchased just over a year ago.  I'm beginning to video some of the progress and post it to youtube and facebook.  Check it out.  Be sure leave questions or advise.

This is great to see that. I did not see it before. Thanks
