I live in WV where we have lots of trees and I have a really big one right beside my pool. I am just diligent about keeping leaves removed in the fall and then once they have all fallen, we are good to go. I open my pool pretty early each year since we go from winter to summer temps pretty quick most years. I always open to clear water although there will be a little dirt on the bottom. That is no big deal; a quick vacuum easily takes care of it. There have been no issues at all for us without using a pool cover. Haven't used one in years. (Another former moderator who lives in NE Pennsylvania also never covered his pool in the winter without issue.)

Just something to think about. In my opinion, winter covers are a big PITA!
