"SARATOGA, Wyo. — The North Platte River in southern Wyoming has been so low in places lately that a toddler could easily wade across and thick mats of olive-green algae grow in the lazy current.

Blistering heat waves and extended drought have raised water temperatures and imperiled fish species in several states."
