The Bureau of Reclamation schedules its high water ramp up to cooincide with peak flows of the Yampa (its largest tributary). This is to create a more natural spring runoff and allow as high of flows as possible downstream to scour the river and benefit endangered fish such as the colorado pikeminnow, humpback chub and razorback sucker. The Yampa is a freestone river so it is very dependant of the weather at the time. Flows usually begin to be gradually raised historically between the 2nd and 3rd week in May.
