More than 20 years after being listed as an endangered species, the pallid sturgeon is just treading water in the Missouri River. Thanks to an ongoing restocking program, the fish population is stable but not recovering.
Epic water battles are the stuff of history and legend, especially in the West. And as a severe drought drags on in the Midwest, a water war is being waged over a river that irrigates agriculture in Colorado, Nebraska and Kansas.
It's that last border crossing where this water war is under way. Kansas has gone to the Supreme Court to argue that Nebraska uses too much water from the Republican River, and that there's not enough left for Kansas farmers.
