There were lockers near the major rides. I used the ones near Kraken and Manta. The smaller lockers were $1, which I used for a standard backpack and jackets no problem, and there were larger ones which I think were $2. The lockers require quarters, and there were change machines there as well. I also THINK there were cubbies at some of the ride boarding areas to stow stuff during ride. I am not absolutely sure about that and may be thinking of another park. Hopefully someone can verify.
