How much of the pond was covered and what was the light blocking percentage of the shade cloth
The pond is rectangular and the bottom sloped to facilitate draining. 90 feet long with the deep end 40 feet wide and the shallower end only about 25 feet. I had the shade cloth over the shallow end about 25 feet of the pond all the way across. Shade cloth was the densest I could purchase.
I don't think my partial covering was a good test of how well shade cloth would work. If I was to seriously do this I would place it over the entire pond and in that case I believe it would keep temps down a little.
