Drought: Will there be a call on the Colorado River?

If water is needed [in the Lower Colorado Basin] a “call” is made to upstream entities, like the headwaters, to demand water downstream. It’s called a Colorado River Compact call.

A call may be imminent as the continuing drought is mightily affecting all of the Colorado Basin.  If so, then there will be battalions of lawyers and brass-knuckle water wars.
