60+ cameras take photographs every daylight hour of every day.
These photographs help us see a watershed through time.
The camera systems are placed throughout the 90,000 square-mile basin, from its headwaters along the Continental Divide in the Colorado Rockies to the river’s confluence with the Missouri River on Nebraska’s eastern border. Like chapters in a book, each time-lapse camera tells one part of the story of that proverbial drop of water as it makes a journey of roughly 900 river miles through the heart of North America.
