At 3 feet, sandbars are exposed in the river and this can be a lot of fun. Between 3 feet and 5 feet, paddling is predictable and easier. When the river is above 5 feet, you shouldn't go unless you are an experienced rower. Shoes that stay on one's feet are a must when paddling local waters. Both saltwater and freshwater river bottoms may be uneven or have sharp shells.
Shoes provide better footing when leaving the boat.
Always wear a life jacket and have plenty of water to drink. Insect repellant, hats and snacks are insurance for a good time. Sunglasses with straps to keep them on are advisable. Canoes can accommodate a medium size cooler in the flat, center portion of the craft. When kayaking, you may need bungee cords to secure your cooler or water bottle, although certain types have storage compartments.
