Here's a story on efforts to save the Kootenai River white sturgeon. Same story -- fundamentally alter habitat, overharvest, become concerned as the species enters the extinction vortex, etc. But hope springs eternal.

Neat.

White sturgeon are neat fish but I am sure they live other places than the Kootenai River, right?

The Kootenai population is distinct, arguably a different species. It's like different river runs of salmon, all the same species but distinct genetics reflecting a series of adaptations. Everything else is just hatchery salmon...

Hello Bruce

I was reading an old Outdoor Life magazine today which had a brief article on these same fish I believe...it was talking about how the water level is dropping or something like that and they are getting more and more reports of this fish jumping into boats...even hurting some people. Some claim the fish are doing this on purpose...imagine that - smart fish fighting back... I will have to double check tomorrow as the magazine is at work but I am pretty sure the article is about Sturgeons and I believe it mentions the Kootenai.

Why would those White sturgeon be a different species from any other White sturgeon?

Calling them a different species is too strong. But they are a well-defined population with somewhat different physical features, living geographically separated from other white sturgeon with that separation having lead to adaptation to local conditions. It's part of the variation in nature that we as humans often do a good job of reducing (your mileage may vary, of course).
