nets adjoining each other but fishing at three 

 depths: 0-15 feet, 15-30 feet, and 30-45 feet. 



Type VI — Floater. Two type III nets at- 

 tached end to end, 100- by 6-foot white nylon 

 mesh, 3/4 inch. 



Type VII — Submerged. A type II net with 

 an extra lead line that caused it to sink and 

 fish the bottom. 



Fishing began June 12 and continued until 

 October 6. During June and the first part of 

 July, sets were made at various depths from 

 3hore to midlake and from one end of the 



lake to the other at locations shown in figure 

 21 to determine where sockeye salmon could 

 be found. Stations I, II, and III in figure 21 

 were also used in the limnological studies 

 that will be discussed later. From mid-July 

 through mid-September fishing was continued 

 at only two general locations: At station I, in 

 the littoral zone from shoreline to dropoff; 

 and at station II or III in midlake. From 

 mid-September to October 6, only the midlake 

 locations were fished. By fishing a littoral 

 and a deep-water area simultaneously, how- 

 ever, limited comparisons of abundance in the 

 two habitats could be made.
