You can bring a cooler with food and drinks, just no alcohol. For clothing you can wear and bring anything, there's 1 slide you cannot wear a shirt on. They have lockers and changing areas. They do search your bags before entering the park
You can bring in food, closed beverage containers (no glass), towels, extra clothing to change into, sun screen etc. They really dont have a dress code as long as your bathing suit is family friendly. Ive seen people come in with just wearing their bathing suit and no cover up
I'm not sure but I do know that they do check for alcohol
