STREAMS
Location of Streams
• Streams can be found everywhere!
Physical CharacteristicsSTREAMS ARE:
• Usually freshwater• Cool (Temperature)• Narrow – Wide• Shallow-Deep • High oxygen levels• Few tributaries = Flows
Quicker• More tributaries = Flows
Slower• Flows into one direction
Base of food web• Microorganisms
• Algae
• Plants(Emergents, Floating, Submergents)
Types of animals that can be found• Flies (Dragonflies, Caneflies)• Waterbugs (Water scorpion,
striders, boatmen)• Beetles • Crayfish• Scuds• Snails• Leeches• Fish (Bluegill, Salmon, Bass,
Catfish, Sculpin, Minnow)• Snakes• Turtles• Frogs
Facts• A lot of streams in the world
are polluted, and there has been a major decrease in animal life.
• Sewage and runoff flows into streams
• Streams are still contaminated with mercury from the gold mining days.
