Ryan, I'm not sure I have a leak. A pond I use for comparison was also low. We had very low humidity for the area for about a month after the remnants of Ike rolled through. Plus it has only been about 10 months after major underwater borrow areas have been covered with water since some repairs were made, so it may still be "wicking" as well

I still have some areas of exposed clay (it's getting smaller every week), but I had hoped to have over applied enough to compensate for additional runoff.

I think your "Floating" floc was actually algae and as the gasses created by instant decay dispersed, it sank. When I was lazy and just poured in alum and lime, I had tons of algae gas-up and float up from the bottom afterward. It lasted less than a week. It also didn't clear anything.
