Ok, I've planned to do some outdoors pond to keep a large varied collection of turtles. I plan to use pond Liner to make custom shapes and sizes, but my main concern is rain. How do you guys go about keeping the water from overflowing if you dont have a pump when it rains? I plan to keep natural ponds only filtration would be thru water hyacinth, duckweed, and water lettuce. I dont want them to flood, and ruin the habitat or any eggs laid. Also any recommendations for heavy duty pond liners?? Or any advice on how to renforce it?
Thank you
