Couldn't decide what was better, this thread or /diy/
Here in upside down land we have dams on farms, it's like a big shitty swimming pool filled when it rains once per year
If the base of it isn't made from clay & sealed properly then ofcourse it leaks and you lose a lot of water.
However you can use plastic liners like pic related
Paying some cunt with a special tool to melt liner strips together costs a lot, so because I'm cheap here's my plan in the next post, feel free to critique
