We received exactly five inches of rain in August, but the ponds (even the non leaker) still finished the month at lower levels than starting. The most rain in one 24 hour period was 0.88 inches. We had 16 days with at least a bit of rain, but no significant run-off all month. The average rain was a bit over 0.3" in a day. All it did was make the grass grow, and totally annoy the hay producers.
