Gauge Description:

Scott Barnes: "The gage is after another river, and after the power plant discharge." So the gage isn't totally reliable. There's a painted gage ("Flintstone gage") at the putin; that's the one that the locals use.
The minimum level ("stage") on the USGS gage is about 4 feet.

Compliments of Mark Rollins: For a correlation between the USGS and Flintstone gauges try the following formula:
Boater's Gauge = 5/3(Gaylordsville Gauge - 4') + 1'

800 -10000 cfs barely runnable-high runnable IV gauge is important or has warning When the Hydro Plant is offline (as it is through the winter of 2015/16) the whole run is easily navigable down to around 650 cfs (~1ft on the boater's gauge)

Reports give the public a chance to report on river conditions throughout the country as well as log the history of a river.
