Lincoln Beach is a historical site in the United States featuring submerged concrete structures and remains of old pools. This artificial reef and wreck site is suitable for advanced divers due to strong currents and low visibility, which typically ranges between 2 and 3 metres. Depths vary from 3 to 20 metres, with an average of 7 metres. Entry is via the shore. The environment supports a variety of regional marine life and invertebrates typical of the habitat. Divers should be aware of potential hazards including cold water, strong currents, and overhead environments. Snorkelling is not recommended at this location.

Fontainebleau State Park Beach offers a shallow, sandy-bottom entry point on the North Shore of Lake Pontchartrain. This site is suitable for beginners, with depths ranging from 1 to 5 metres and an average depth of 3 metres. Divers and snorkellers can expect mild currents and visibility between 2 and 5 metres. The habitat supports various temperate freshwater fish and invertebrates. Due to the shallow nature of the area, it is primarily used for observing small crabs and minnows in the shallows. Hazards include boat traffic and low visibility. Facilities available at the park include parking, toilets, and showers.
