Good advice! I have Mike Otto's book, but haven't read it in several years. Probably time to read it again.

I am definitely not moving spoils more that 50 yards. My biggest concern was that wet blue clay looks too slick for dozer work or pulling a pan scraper.

I was going to alternate steep banks (to reduce the substrate for FA growth) with gentle banks (spawning and human egress).

Your post also implies that beneficial plants compete for nutrients and therefore help suppress the FA. I had forgotten that bit of information. Obviously, I need to do even MORE searches on Pond Boss before breaking ground.
