I don't know how many folks caught this in the news yesterday, but a body surfer downed in the park yesterday afternoon. 45 yrs old, no pfd, core temp clothes, etc...
Police: Man body surfing in Clear Creek drowns | 9news.com
I was at the Rec Center swimming with my son an hour ago and talked with a Rescue Worker while I was there and I asked him about it. He said that they are working to close the park at 1:30 today to Tubers, Swimmers, and Surfers. I would guess that it will be the same as Boulder Creek which is open to Whitewater Crafts. I am not sure about Riverboards, you'll need to contact Golden to find out.
The river looked great, bankfull, and well defined. It had tiny eddies and most were in the trees. Be safe and have fun the water is still coming up.
