Just how ******* retarded am I? I never knew rivers changed their "trajectory" naturally over time... common.

Yup, we live in a constantly changing world. This particular phenomenon is due to erosion of the water current breaking down the landscape, particularly where it bends.

It's not trajectory, it's meander. The meander of a river. This river is meandering

I've always used meander as a colloquialism meaning "to walk about."

That derives it's use from the meander of a river though.

It technically means "A meander, in general, is a bend in a sinuous watercourse or river", but yes, it can be used as "to walk about"

I'm really curious what happened about 3/4ths of the way down the timeline that caused the river to flow down a completely new area? Maybe a beaver dam blocked the old way?

2 parts of the river grew too close together and merged rapidly, this caused the water to no longer go in the original trajectory around the miscellaneous bends and dried them up. Sometimes water is left in a horseshoe pattern completely isolated from a river, which is a frequent occurrence. You can see it happen many times throughout the river. The one to which you are referring just happens to be the most dramatic.

A Stølum number is the length the water travels from point A to point B divided by the direct distance from A to B.   
This can change as a river changes course. The ratio, however, commonly converges to approximately π.
