Here's an aerial photo of my pond. My son-in-law is in commercial real estate and snapped a brief series of our place last January when he was getting pictures of some local commercial properties.
Think you can see why we dubbed it "the chara monster" -- almost looks like an evil smiley face! The open areas appear blue-green ... whether that's the residual effect of an October Aquashade dosing, I cannot say. I just hope it's not indicative of accumulated copper! If so, then man you could mint pennies from that pond bottom!

The little wooded area to the right is where the spring stream flows in. That's also the site of an ongoing landscape project my wife and I began a few years back ... it just keeps on going! -- Mike
