CB,

Thanks for the input. Sound like a cool design/muck control. Where I'm from here in central Illinois you would have to drive 15 miles in any direction to find 20 feet of elevation change. I created a 20 foot sledding hill from the clay spoils of my main pond which might just be the highest point in the county. Maybe I should apply for an official plaque or something wink Flat, black dirt... Regarding the Black Crappie, if what I've read is accurate you won't have any problems getting crappie to spawn, the problem is getting them controlled once established. I stocked Hybrid Crappie in my pond as they aren't supposed to be as prolific. I've got 2 young boys that will be happy to act as Crappie control if the population gets out of hand.
