The Environmental Protection Agency has ordered a Sandhills rancher and Cherry County to take "immediate steps" to halt and repair damage to a remote Nebraska stream inundated by a deluge of sand and sediment. The EPA said the Snake River, which hosts canoers and trout fishermen, was transformed from a "deep and narrow" spring-fed creek into a wide and shallow, sandy waterway for about three miles after an estimated 1.6 million tons of sand washed into the river. That's enough sand to fill an area the size of a football field about 540 feet deep.
