Table 3. — Number of sockeye salmon passed upstream through the weir each day and 

 cumulative upstream count at Hidden Creek, 1959, 1960, and 1961. 



Table 4. — Sockeye salmon escapements into Hidden, 

 Up-a-tree, and One Shot Creeks in 1959, 1960, and 1961.

of fish ascended the stream and occupied redd 

 sites while other fish were already spawning. 

 Some late fish spawned adjacent to previous ar- 

 rivals, and others continued on to the upstream 

 spawning areas. This distribution of spawners 



was not measurably altered by differences in 

 their numbers, as evidenced by the distribution 

 throughout the season of the considerably fewer 

 fish in 1961. 



Although the distribution of spawners from 

 year to year varied more in Up-a-tree than in 

 Hidden Creek, Up-a-tree Creek had areas of 

 consistently high and consistently low spawning 

 density (Figure 3). More spawners entered 

 Up-a-tree Creek in 1960 than in 1959 or 1961, 

 and the 1960 spawners were distributed more 

 uniformly along a greater length of stream than 

 either the 1959 or 1961 spawners. In 1961, rel- 

 atively few fish spawned in the lower sections 

 of the stream. 



The distribution and number of spawners in 

 One Shot Creek was similar for the 3 years of 

 the study (Figure 4, Table 4) — here spawners 

 consistently concentrated in the upper and lower 

 ends of the stream.
