No, it is different. The pickup isn't directly in the stream churning up gravel
Quad's, dirt bikes, jet ski's etc are just as annoying - too many of them buzzing around making a god awful noise.
On any smaller river jet boats speed should be restricted. Say 15km per hr.
Less power / speed thus gravel not churned up.
Or whatever speed it takes to which it does not affect the fish/spawning...
Enforcement would be an issue but with signage ,smart phone cams & heavy fines possibly jet boat owners will put it in a crawl speed.
Jet boats can do there racing on the main Fraser. ( even there 50 km max )
