People please realize that this is a OFF-LEASH DOG PARK!!! It has a canal with reasonably clean water that pretty much all the dogs play in. That being said, if you are NOT willing to get a little wet from shaking dogs then don't bother. Personally, my dog loves it here but I never enjoy hearing someone complain about getting wet or annoyed by dogs...AT A DOG PARK. If your dog is well behaved, then by all means come and check this place out!
Hike at your own risk. This open space lies due east and well within the fallout zone of the former Rocky Flats factory. That facility manufactured parts for nuclear bombs out of plutonium and both airborne and waterborne waste has been documented in this area. The Woman Creek reservoir, which is visible past Mower Reservoir on the west side of the open space is a catchment pond for keeping polluted waste from continuing to Stanley Lake.
