Cache Creek season? Options

[Arbo]

I know it doesn't open until memorial day, but when does it close for the 'season'? I have a week off in september and am hoping it's still open so I can go spend several days out there.

Also, I stopped by there only once for a couple hours... is the little creek by the parking area the only water, or is there water further back as well?

Thanks

I stopped out at CC on my way to and way from Denver the over the past two days. Got some color, learned a bit about the site and what to look for. Of note, a new thing there since I last stopped by (in June), now many of the trees have orange painted on them, you are not allowed to dig within 8 feet of any of such marked trees. Which means a lot of ground is now 'off limits'. Just thought I'd let people know who haven't gone there in a while.
