Major project along the Boise Greenbelt

Fellow cyclists who traverse our "crown jewel" Greenbelt are aware of a major project that has disrupted travel temporarily, but hopefully for a bigger long-term good.

Several years back, they began an ambitious "whitewater park" project, intended to give kayakers, surfers, etc., a better experience.  But it's been quite pathetic, so far, at least as measured by person-hours of enjoyment.

Here's the adjustable wave as has existed up 'til now:

It's quite the engineering teat - that water barrier can be adjusted up and down.  BUT - only one or maybe two people at a time are benefitting from the downstream "wave," whether it be surfers or boaters.  It's sad to see 10 or 15 people queued up to wait their turn, while 1 or 2 people take a 30-second turn.

But now it's expanding downstream.  A week or so ago, I snapped some photos... it's far enough along that one can imagine the shape it will eventually take.  Particularly impressive are the temporary barriers, both upstream and downstream, to keep the water out of the project.  (The river runs particularly low this time of year, and the water is being diverted around the project using a canal.)  Supposedly it will be completed sometime this summer.
