I'm gonna disagee. they are not the same at all. you have no idea what 2.1' is measuring. Saggy suspension cables? different reading. Spring flood shifted gravel around? 2.1' before that shift is a different flow than 2.1' after.
that is why usgs visits and recalculates the gauge: they account for streambed changes and provide consistent correlated data.
cfs is a unit of flow: volume per unit time.
feet is unit of distance. what the heck are you measuring?
Enjoy your mystique, but only one of these things meaningfully discusses flow.
