Facts and figures about water and arts

Water has served as the subject and stimulus for many different types of art such as painting, music, and literature and, in several instances, has provided the main subject of the artist’s studies.

Water has been represented in many different ways, sometimes as a symbol or in a stylized form; at other times efforts were made to capture the realistic nature of water, as was the case during the Renaissance in late 15th-century western art.

Often, art has served water cults, contributing images that personify both the physical and metaphysical aspects of water and numerous water divinities.

Facts and figures about waterways

A waterway is any navigable body of water, including rivers, lakes, oceans, and canals. In order for it to be navigable, it must meet several criteria:

  • it has to be deep enough to allow the draft depth of the vessels using it;
  • the waterway must be wide enough to allow passage for the beam width of the vessels using it;
  • it has to be free of barriers to navigation such as waterfalls and rapids, or have a way around them (such as canal locks);
  • the current of the waterway must be mild enough to allow vessels to make headway.

Almost 70% of United States’ agricultural exports travel the upper Mississippi River and the Illinois Waterway system.
