I'd gladly take 6-8 inches off your hands to top up my pool!
I don't mind rain - it's my only real source of water for the pool, I actually like it unlike the rest here who seem to run to the chemical closet when it does rain.
I add chlorine, let it finish raining, check my chemicals, adjust as necessary, let the dust settle, vac to filter (don't want to waste all that nice water I just got for free!) and voila - swimming 1 day later.
