The Upper Missouri River is mostly left to its own devices, allowed to migrate as it pleases. As a result, the river provides complex habitat that may lead to retention and growth of larval pallid sturgeon. The complexity is also vexing for boat drivers because it means that opportunities to get stuck on sandbars are around every bend.
The boat of choice has an aluminum hull with a jet prop. On plane, these boats generally draft less than a couple of inches. Problems crop up when the water is shallower than that or the driver picks the wrong route in complex channels. The sandbars have a tendency to grab hard and hold fast. Getting a stranded boat off of a sandbar can require brains and brawn.
Knowing the river and being able to read the water are key. Using GPS and digital aerial photography, boat crews have even more ways to read the water, but we’ve found that images only two years old can be inaccurate in places where the river is especially active.
