Lake Nicaragua, known to locals as Mar Dulce or Lago Cocibolca,
is the largest lake in Central America. Although the lake is very
large, it only reaches a maximum depth of about 84 feet. The lake
sits at 105 feet above sea level and is connected to the Caribbean
Sea by the San Juan River. The city of Granada lies on the shores
of the lake.
Because of the San Juan River, Granada is an Atlantic port in
spite of the fact that it is closer to the Pacific Ocean. Before
the Panama Canal was built, there was much talk of constructing
an inter-oceanic canal through Lake Nicaragua. The idea stills
surfaces from time to time but the United States usually shuts
it down, as it would create competition for the U.S.-controlled
Panama Canal. A project called “Ecocanal” is discussed
periodically.
Although it is a freshwater lake, Nicaragua contains sharks,
swordfish and tarpon. The Lake Nicaragua Shark is a type of Bull
Shark which is fully adapted to freshwater. It was once believed
that the two were completely different species until Bull Sharks
were spotted swimming upstream from the ocean into the lake. Based
on geography, scientists believe that the lake used to be a large
bay.
