LOUISVILLE, Ky. (WHAS11) -- Thunder Over Louisville just doesn't mean crowds on the banks of the Ohio, it also means crowds on the river itself.

From swift currents to drinking, to just too many boats, the U.S. Coast Guard responsible for your safety.

Daniel Gallo, Machinery Technician with the U.S Coast Guard explains, “Just maneuvering around in a tight area you know, there's going to be a lot of boats out on the water.”

The United States Coast Guard is one of more than two dozen agencies that help patrol the Thunder crowds.

Officers took our cameras for a ride on the Ohio to talk boating safety and their plans.

Lt. Karol Garrison, adds, “Wear your life jackets. You got to wear your life jacket. They save lives. There's nothing more to it. Second, boating and alcohol, they do not mix. It’s just like driving a car. You can't be boating under the influence.”

Gallo tells us, “When the fireworks are over, everyone is in a hurry to leave or get home. I would just say be mindful and slow down.”

The Coast Guard says do not try and get your feet wet with boating on Thunder, only those with experience should navigate the waters. If you do get in distress, every marine radio has access to channel 16, that's to alert the Coast Guard, but officials say you can also call 911.

The weather is going to be a big factor when it comes to the river levels, which is why many Coast Guard patrols will be ready to respond if needed.

Lt Garrison states, “It is going to be dangerous if the water levels do increase rapidly so we definitely will keep an eye on that.”

The river is wide but has the perfect view. As long as you are equipped and aware, your time on the Ohio should be smooth sailing.

There are certain parts of the Ohio that you cannot access, the U.S Coast Guard will have those areas properly marked.
