What is this? Boundary waters entering Lake Superior in Minnesota?
Naah. Here are some photographs of the overflow from Upper Lake Mary, only a few miles south of Flagstaff, as it appeared on Saturday, 12 February.

Water filled the entire width of the spillway dam, and in sufficient volume that all the flow did not enter the spillway channel directly, creating a new, broader channel.

This view shows only the southern half of the spillway, but the fact that Upper Lake Mary is 100%+ full is evident. Lower Lake Mary is still somewhat less than total capacity, but it's waters have reached to the dam on Upper Lake Mary.
