Rosgen Stream Classification
100
Aquatic plants found in the littoral zone.
What are macrophytes
100
When rivers enter open water such as an ocean and divide into multiple channels called distributaries.
What are Deltas.
100
Specific places where organism reside and the primary feature is the substrate.
What is microhabitat
100
Stream types that occur on steep mountain slopes.
What is Aa+ and A.
200
Light penetrates through this zone of the lentic system not associated with the shore.
What is the limnectic zone.
200
The amount of water flowing past a certain point in a given unit of time.
What is discharge or flow
200
Plant biomass produced outside the system.

300
When velocity is low, water particles flow steadily parallel to each other and to the channel, without mixing.
What is Laminar Flow
300
Environmental and biological factors vary continuously from headwaters to mouth of river.
