If it's only 0.25 in/day then you must have pretty good clay.
You're losing
0.25 in = 0.02083 ft
8.5 acres * 44100 ft^2/acre = 374850 ft^2
374850 ft^2 * 0.02083 ft = 7809.375 ft^3 (cubic ft)
7809.375 ft^3 * 7.48 gal/ft^3 = 58414.125 gal
So roughly 60,000 gal/day.
10 gal/min will give you 14,400 gal/day.
100 gal/min will give you 144,000 gal/day.
You'd need to pump about 40 gal/min to stay ahead of the evaporative loss.
