I have never seen people swimming in with the dogs and don't know if it is allowed. Pond seems pretty clean to me, and my Golden puppy enjoyed it immensely.
No, the water is only for the dogs. They do have a flotation device if needed to get your dog out. Honestly, since it is a sitting pond it isn't very fresh. I would recommend going to Tanner dog park a little past Sugarhouse. They have fresh water and at the very end of the trail there is a deeper area where you and your dog can get in together. My dog absolutely loves Tanner Park! It is one of our favorites because of the clear, clean water. For swimming or just splashing in it.
