Here’s the entire Rio Grande right now, which easily fits through the slot on the east edge of the Angostura diversion dam north of Albuquerque. No water is being diverted. That’s the whole river you see. This is not unusual. The flow measures about 600 cubic feet per second at the San Felipe gauge a few miles upstream. The median at this time of year is in the mid-700s.
