From the Santa Barbara Independent, in a commentary by Arve Sjovold:
“Can a man drown crossing a river that averages one foot in depth? The answer is, of course, yes. An average cannot describe how wet you’ll get wading a river with a deep channel and a broader shallow run. In fact, the average is likely to represent only two points in the depth profile: the point where one descends and the point where one ascends the sides of the deep channel.
“What does this math puzzle have to do with the State Water Project, past and future, especially the proposed ‘Twin Tunnels’ project?”
