the picture mentions 100-1000 winter gpm flow rates....how was this measured/observed? Your spillway uses a notched weir overflow so you should be able to calculate the outflow based off the pool height over the notch base in comparison to the notch angle/width dimensions. Maybe you've already figured this out?
If I had to guess, my winter flow rates are between 50 and 250 gpm after ice up - 1.25 acre, 14' max depth, 8' average, never had a winter kill.
