No entry fee unless there is a special event that requires one.
There's not a fee to use the park. It's open every day of the year, and like @Cory Casterline said, if there's a special event, they might charge an entrance fee. But only for the area of the park that is sectioned off for it. The rest of the park is still open.
No fees. It's free to run
It's free and an awesome place to enjoy the weather and the water.
