Most are natural freshwater, but some may be saltwater.
A lake on the ocean, also known as a coastal lagoon, has unique ecological features such as a mix of freshwater and saltwater, diverse habitats for marine and freshwater species, and high levels of biodiversity due to the combination of different environments.
Saltwater is denser than freshwater because it contains dissolved salts and minerals, which add more mass to the water molecules. The increased mass of the saltwater results in a higher density compared to freshwater, making it sink below freshwater.
Freshwater is less dense than saltwater because it has a lower concentration of dissolved salts. This difference in density causes freshwater to float on top of saltwater, creating distinct layers when they meet.
There is by far more saltwater in the world. The oceans of the world are saltwater, and by volume the oceans compose over ninety percent of Earth's water.
A ship floats at different levels in freshwater and saltwater because saltwater is denser than freshwater. The denser the water, the higher the ship will float. This is due to the buoyant force acting on the ship, which is influenced by the density of the surrounding water.
Lake Erie is a freshwater lake.

Freshwater.
Lake Maracaibo is saltwater, being an estuary rather than a true lake.

Most lakes contain freshwater. From this fact, I'm assuming it is made out of freshwater, rather than saltwater.
No, all LAKES are freshwater. OCEANS are saltwater. Lake Michigan is a freshwater lake, but the answer above is false. See, for example, http://en.wikipedia.org/wiki/Great_Salt_Lake or http://en.wikipedia.org/wiki/Lake
Fresh water
Lake Okeechobee is due to freashwater
Saltwater but with a hint of freshwater
Freash water
No. Lake water is freshwater and ocean water is saltwater.
