Inflow is variable. Can go from less than 1 gpm up to 15 gpm depending on air temperature. Since it's lined I don't have to worry about seepage, so I can greatly minimize my water use most of the year.
Those stones are each 18 in X 15 in. X 8 inches tall. The guy I bought them from said they weigh over 100 pounds each, but I never weighed one. They were seconds, so they only cost five bucks each. It was really a steal.
