Before damming, Walnut Creek was one of the only reliable streams in this arid region, flowing consistently each spring with the melting of snowpack on the Colorado Plateau. After the Upper Lake Mary Dam was constructed in 1941, Walnut Creek dried up below the Lower Lake Mary Dam due to increased water diversions. Since then, the creek has flowed only during monsoon rains or exceptionally heavy snowmelt.

The creek makes a sharp turn to the east at Fisher Point and carves the narrow, winding Walnut Canyon, a limestone gorge up to 600 feet (180 m) deep. About 10 miles (16 km) east of
Flagstaff it passes through

336:. The San Francisco Wash is sometimes considered the lower part of Walnut Creek, and the total length of the stream would be 55 miles (89 km) if this is included.
