Usually, except right after a rain, the creek is about 4 to 5 feet. But 9 feet is common after a rain. Back in Western Nebraska, the Platte river is typically not deep enough to canoe in... "A mile wide and an inch deep, too thin to plow, too thick to drink" This is often attributed to about three different western rivers, and the North Platte is one of them as is the South Platte and the Powder. It's probably been stolen by others I don't know of as well.
