Stream Classification - Wetland and Deepwater 



Habitats (10) Compared to Rosgen, 1985 



Riverine (10, 7, 6, 5) 



Tidal (10) 



Lower Perennial (10) 



Upper Perennial (10) 



Intermittent (10) 



Habitats contained within a channel and/or wetland (assuming also 

 riparian) habitats dominated by trees, shrubs, persistent 

 emergents, emergent mosses, or lichens and habitats with water 

 containing ocean-derived salts in excess of 0.5 parts per thousand 

 (10). [This definition generally fits well with (7).] 



Low gradient with water velocity imder tidal influence. Streambed 

 is mainly mud with occasional patches of sand (10). Would be 

 similar to a Rosgen C4, C5, C6, F4, F5. 



Low gradient, low velocity water, no tidal influence with water 

 flowing throughout the year. Substrates consists mainly of sand 

 and mud (10). Would be similar to Rosgen C4, C5, C6, F4, F5. 



High gradient, high velocity. The substrate consists of rock, 

 cobbles, or gravel with occasional patches of sand (10). Similar to 

 Rosgen A and B stream types. 



The chaimel contains nontidal flowing water for only part of the 

 year. When the water is not flowing, it may remain in pools or 

 surface water may be absent (10). (This definition would also 

 include ephemeral streams, those that only flow in response to 

 precipitation.)
