Let us know how it works out anthropic.
Or you could just do what I did with my sediment pond. Let the FA get out of control and the floating mats provide shade.
I did notice tonight as I fed around my main pond (which has a small amount of FA mats just around the edge) the CC could come right from under the FA mats is less than a foot of water out to get their supper. I figured they were feeding under the FA but they may have been using the shade. Mid 90's here today. That is darn hot for the first of June for us.
