If anyone has ever applied for one of the 4 rivers permits in Idaho, you've seen the hydrographs that show average flow curves for for a river over a season. Are those available for the Colorado River anywhere. I know how to get current flows, and even historical peaks, but I can't find good historical information. Thanks.

You can also go to the USGS web pages with the recent flow data, then at the "Available Data For this site, " select "Surface Water, Daily Stream Flow" and you'll be able to select which period you want graphed. For example, for Gore Canyon (Co. at Kremmling), you can choose a period from any time in the last century (when they have data available) and graph it. If you want to know what it was like during an epic year, like 1984, then just put the dates in and it'll serve you a custom-made graph.
