I'm wondering about this as well, as I don't think I've ever sorted out what's what on the Dowd gauges. The phateye page has 3 gauges:
Eagle below Gypsum, Eagle at Avon, Eagle Dowd Chutes. Does the river level gauge on the bridge correlate exactly to any of these? If so, does anyone know the ft gauge to cfs conversion?
Also, are inflows fairly consistent between stations. I have it in my head that I did this run around 2300 on the Gypsum gauge last year and am wondering what that correlates to on the bridge gauge. Can I just substract a constant to figure out the likely reading on the upper gauges or does it vary widely?
