in the past we used this trail a lot. However, a couple of years ago, it started being patrolled daily by the city of Boulder animal control ticketing people for dogs swimming and being off leash. In the newspaper, they bragged of being there pretty much all of the time. It is under the control of the city of Boulder so those rules apply, and are very different from the Boulder County rules we were all following. it was just a convenient little county park. Too bad it became a highly - policed place to play with your dogs.
