I thought of another option that I have been told some people with small trout ponds do to keep warming down in the hottest part of the summer. They float that pink or blue 4 X 8 or 5 X8 foam board that you can get at building supply stores around the edges of the pond. Don't use the less dense white foam as it will just saturate or fall apart. You may have to figure out a way to keep it from blowing out though.
I may have to do this myself this summer if we get a repeat of the 100 plus degree days of last summer.
