Is the park open right now, because here it says open, but on metro parks website it says closed untill july 5?

The park is open, including the baseball field and playground and water fountain and restroom, but the pool doesn't open until July 5th. There is a small splash pad next to the playground that is open now (after 10 am every day) but the big outdoor pool and playground is not open. Neither is the small snack hut: which should have the same hours as the pool

Yes, it's open. The pool however, I haven't seen open yet
