I put together data in 2017, with few points < 500 cfs. Of the equations I tried, the best fit was:
PV gauge = (10.64 * HewCFS)/(2689 + HewCFS)
There's more scatter than there should be ~ 1,000-1,500 cfs, so perhaps I should update this. Nonetheless, it's a pretty reasonable fit up to about 3,000 cfs (r2 = 0.96 ).
