Average depth and range ■ — 

 The average depth and rajige in inches 

 as determined from the survey. Aver- 

 age depth >/as determined where a flow 

 measurement was taken. Range applies 

 to depths for the entire stream. 



Flow and range . --Discharge 

 in cubic feet per second (cfs), 

 usually deterrained near the mouth of 

 creeks. Date and place of measure- 

 ment and relative stage of stream 

 level are indicated when Icno'.m. 



Total accessible spa-yming 

 area . --The total accessible area in 

 acres and sq^oare yards. 



Potential spasming area . — 

 The spasming area in acres and square 

 yards. Potential spasming area was 

 determined by deducting from total 

 accessible area the percentage of non- 

 spaimable pools, riffles, and areas 

 iTiade nonspawnable by \ra,ter velocities 

 exceeding 5 feet per second (fps). 



Potential spawning area for 

 beaches has not been determined. Area 

 irtilized is given for beaches as de- 

 termined in 1961. 



Bottom quality . — The mean 

 percentage of different bottom types 

 as determined from the survey. 

 Bottom type (gravel size) was arbi- 

 trarily chosen as <l/8", 1/8 "-3", 

 3"-12", >12", and unlmoxra. 



Watershed . — A brief descrip- 

 tion of the 1-ra.tershed and stream. 

 Such things as drainage area (to the 

 nearest square mile as deterrained from 

 contour maps with a compensating polar 

 planiiiieter), type of valley (glacial, 

 stream- cut, etc.), vegetation, flood- 

 ing, source, and obstructions are in- 

 cluded . 



Gradient . — Given in feet per 

 mile as determined from contour maps. 

 Field gradient measurements have not 

 been made. 



Water velocity . — Given 

 in fps and determined when a flow meas- 

 urement ira,s given. 



Air temperature . — Given 

 in degrees centigrade along with 

 date of measiurement. 



Water temperature . — Given 

 in degrees centigrade along with 

 date of measurement . 



Pools and riffles . — Dis- 

 tribution, abundance, and size of 

 pools and riffles, though desirable, 

 were not available. These data 

 should be gathered at a futvu-e date. 



Red Salaion Runs 



Percent of total escape - 

 ment .--The peak spaiming ground 

 count in a stream expressed as a 

 percentage of the total escapement. 

 Four categories are used: <lfo, 

 1-ij-fj, 5-9'/o, lOia or more. Tlae date 

 of peak count is also incl-uded. 



Escapement range . — Min- 

 imum-maximum escapement to a par- 

 ticular spa^^ming area. 



Time of occupancy . --The 

 period of time the spaiming area 

 is occupied by red salmon. 



Peak of spawning . --The 

 period of time when the most red 

 salmon are spa-i-ming. 



Distribution of spammers .-- 

 The distribution of spaiming salmon 

 determined from all available in- 

 formation.
