Hm-mh.Save draining the pool and removing the liner and starting again, is there any way to get this high end down lower where it needs to be?
Hire a mole wrangler, with a team of trained moles?
Do something suspicious that causes the NSA to tunnel under your pool so they can spy on it, causing the ground to subside due to low quality work by gov't bureaucrats?
Seriously, I'm not sure there's a practical way to do that. You can sometimes 'hydro-jack' concrete pools . . . but it's not that great of a solution, and won't work at all on a liner pool.
