Chattahoochee

Note that the flow levels on the Main page and Flow Info page are very WRONG and misleading. The gauge reference has been switched from the Cornelia to the Leaf gauge, but all the reference / guidance info is still based on the Cornelia readings. The Leaf gauge is a better indicator of what is happening on the run, but the info on these pages will mislead people to run this at bone-dry levels. Also, in researching the USGS historical data for the two gauges it appears the Leaf gauge DOES NOT show high water events correctly. It appears to clip/limit the level reading for everything above 2100cfs (a medium level). This will mislead people into running the river at very high & dangerous levels if only the Leaf gauge is used. Here is a better reference table for the Leaf Guage:

< 2.5 = Very Low;
2.5 - 3.5 = Low but runnable;
3.5 - 4.7 = Good for a wide variety of paddlers (II-II+), surfing begins to get good.;
LEAF GAUGE STOPS WORKING ABOVE THIS POINT. LEVELS BELOW ARE FOR THE CORNELIA GAUGE
2.8 - 4 = Class III whitewater, good surfing, good flow range;
> 4 = High water, additional skill required (III/IV), not good for beginners. ;

Here is the full correlation between the two gauges. The Leaf clipping at 2100cfs occurred at the last high water event on Feb 24 2016. It should be assumed it will mislead on the next high water in the future - check the Cornelia gauge to be safe.
