STREAM HABITAT 



Backwater - slow water area out of main stream channel 



Pool - deep, slow water area in the stream 



Riffle - shallow area where the surface is influenced by the stream bottom 



Glide - run area with velocity < 0.3 m/sec 



Run - deeper than a riffle, no Whitewater, too fast to be a glide or a pool, 



velocity > 0.3 m/sec ^ 



Rapid - Whitewater, deep fast water, influenced by stream bottom and/or bank 

 Pocketwater - a run or riffle with boulders ( >30 cm in diameter) which create 



numerous small pools 



LOCATION 



Loaf - loafing on a rock or log 



Bank - on the streambank ff 



Edge - at the very edge of the stream next to the bank, in the bank eddy 



Bank 1/3 - beyond edge but in the third of the stream closest to the bank 



Center - in the water in the center 1/3 of the stream, not in an eddy 



Eddy - in an eddy created by a rock or a log 



SUBSTRATE 



Gravel - 0.2-7 cm (0.1-3") diameter Boulder - >30 cm 



Cobble - 8-30 cm (3-12") Bedrock - no loose fill 



CHANNEL TYPE 



Straight - Stream channel linear, structurally controlled by a "V" shaped 



valley, no movement of channel during peak flows 

 Meander - Channel follows sinuous curves, deep pools seperated by shallow 



riffles, appears to shift slightly during peak flows 

 Curved - Stream channel curves or zig-zags more abruptly than a meander, 



channel structurally controlled by a "V" shaped valley, no movement 



of channel during peak flows 

 Braided - Channel located in flat-bottomed valley, midstream bars occur and 



divide the stream into several intersecting and shifting channels 



OVERSTORY AGE 



Seedling - 1-10 yrs old, < 4.5' tall Immature - 70-100 yrs old, DBH 9-14" 



Sapling - 10-40 yrs old, DBH < 5" Mature - 100-160 yrs old, DBH 14-20" 



Pole - 40-70 yrs old, DBH 5-9" Old growth - >160 yrs old, DBH i»20" 



HUMAN ACCESS 



'Adjacent - established area of human activity maintained within 10m of bank 

 Near - established area of human activity maintained within 10-50m of bank 

 Accessible - •_>50 ra from human activity, accessible by car or trail 

 Inaccessible .- >50 m from human activity, not accessible by car or trail 



DEBRIS 



Bridge - log across stream 



Collapsed bridge - log across stream, collapsed in middle of stream 



Ramp - one end of log in stream, other end on the bank 



Drift - log in stream that is not close to either bank 



LOAFING SITE - rock or log in stream completely surrounded by water, suitable 



for resting site 

 VEGETATIVE OVERHANG '- vegetation over the stream within 12" of water surface
