DIFFERENT BODIES OF WATER...

A STREAM
is shallow, narrow, natural body of of flowing fresh water confined by opposing earthen banks running in parallel direction with the steam's flow.  In general, streams run slow enough and are sufficiently shallow and narrow enough to be safely traversed without the aid of watercraft.
 
A BROOK
is a small, shallow stream with a more rapid current, often characterized by a rough or rocky bed.
 
A CREEK
is a small, shallow stream of generally slow moving water, often characterized by a smooth or sandy bed. 
 
AN ARROYO
is a creek that flows intermittently between higher and lower land elevations with varying depth and speed depending upon changing seasonal weather conditions.  An arroyo may transform almost instantaneously from a dry shallow to a swiftly moving body of water.  In dry, mountainous areas, arroyos are often the source of flash floods.
 
A RIVER
is a larger body of water continuously flowing downhill over considerable distance from smaller upstream sources to a larger downstream reservoir, lake, sea, or ocean.  Rivers are generally deep enough and wide enough to require the use of watercraft.
 
A STRAIGHT
is a narrower, shallower body of swiftly flowing water connecting two larger, deeper bodies of of water.
 
A RAPID
is section of fast moving water characterized by a rough, rocky bed and precipitous changes in elevation.  The white water refers to the bubbling, roiling foam that results from the swift water flow twisting and turning over a winding uneven bed.
 
A POND
refers to a shallow basin of still water of less than ten surface acres.  They may occur naturally, but are often man made.
 
A LAKE
(loch) is a large body of relatively still (usually fresh) water which is nearly or completely surrounded by land.  Lakes may result from the accumulated flow of streams (either above or below ground level), or from mountain or glacial run off.  Lakes are characterized by broad basins and may vary in size from approximately ten surface acres to several hundred square miles of surface area.  
 
A RESERVOIR
is similar to a lake, but is the result of human engineering.  Reservoirs may consist of a natural basin flooded by the deliberate damming or redirection of natural waterways, or they may be entirely manufactured by mechanically pumping water into large lined basins.
 
A SEA
is a large body of relatively deep (usually salt) water with limited or no connection to the greater oceans of the world. 
 
An OCEAN
is a vast body of salt water forming the interconnected waterway that surrounds the entire world.  Oceans are deep and derive their currents from a complex system variable water temperatures and weather systems borne out of their varying depths and their absorption of the sun's radiated energy.
