I was on the Colorado Saturday, 3/28, from Corn Lake to 24 rd. Levels were about 3500(?) 29 rd rapid was a decent wave train. I have an 18' bucket and had enough to splash my front seat passengers. It's Rio left pretty much under the bridge, maybe a bit down stream.
There's also a rapid at 5th street, and the confluence. All fun, not sure what they look like at higher levels.
