A couple of questions.

What part of the country are you in? Do you get a lot of snow, ice
and cold weather?

What are your pond dimensions?

I live in the central US and I have found that ice and snow will build
up anywhere it can. Keeping the cover from touching the water really
helps to keep the water from freezing. If you ahve a large area you
might want to add more support that is evenly spaced out. My
dimensions are 12 by 20 and I used 1 inch PVC and just set the
structure on the bottom of hte pond then covered it with plastic. I
glued the fittings with silicone so I could take it apart for storage
in the spring. I used a few rocks to secure it but I think I will use
a 1 inch PVC frame and mount it with tent spikes.

Post those details and I will see if I can make a quick drawing.

I thought of a flat screen over the top, but worried about it collapsing
under the snowload. That may be the way to go.
