Sure, but it'll be fun to have if/when it comes together. For better or worse, most large developments get public money, and developers aren't in the business for altruistic reasons. They want to make money.
If you look at the sources of funds on the PDF this is primarily a private funded venture. The public money bridges the funding gap, but those developers definitely have some skin in the game. Almost $10MM in their own money and $40MM in private debt. Those lenders are going to require personal guarantees. If the project fails the developers will be on the hook for a serious chunk of change.
Also, the Reporter-Herald article says it will have Class 1-6 rapids. I'm guessing they are going to throw a couple sieves, undercut caves, strainers, and keeper holes in there to create the Class 6 artificial rapids.
