Tributaries . — Tributaries used by spawning 

 salmon are listed by distance from the mouth of the 

 main stream, by direction, and by importance . 

 Tributaries not used by salmon, but numerous, are 

 mentioned under "Drainage. " 



Salmon schooling areas. — Based on survey 

 records, major salmon schooling areas are listed 

 where specific locations have been observed for an 

 individual stream. 



Spawning areas. — Major areas are described 

 by distance above high tide or from a reference 

 point in the stream. 



General notes. — The notes include data 

 pertinent to the upstream areas that are of interest 

 and importance in the description of salmon escape- 

 ments. 



entered in this column Include survey conditions, 

 behavior and distribution of salmon, and salmon 

 observations beyond stated survey distances. 



Weir Record 



Salmon escapement counts made by weirs 

 operated by the U. S. Fish and Wildlife Service 

 and the Alaska Department of Fish and Game 

 follow Escapement Record when available. 



Escapement Record 



Stream name. — This appears in the center 

 of the first line of the heading. 



Stream number. — The new and old numbers 

 appear on the right side of the first line of the head- 

 ing on the first page of the escapement record. 



Date surveyed. — Surveys are listed chron- 

 ologically. 



Miles surveyed . — Distances are given as 

 measured along stream courses to the termination 

 point of the regular survey. Ground surveys are des- 

 ignated by "G" and aerial surveys by "A. " These 

 symbols precede miles surveyed. 



Surveyed by. — Initials of surveying 

 organizations are listed as follows! Alaska Depart- 

 ment of Fish and Game, ADFj Alaska Salmon In- 

 dustry, ASIj Fisheries Research Institute, FRI; 

 U. S. Fish and Wildlife Service, Bureau of Com- 

 mercial Fisheries , FWS; and U. S. Forest Service, 

 USFS. 



Pinks, chums, other species. — Abundance 

 of salmon observed during surveys is given as a 

 numerical estimate. Estimates of secondary species 

 are usually less reliable than those for the primary 

 species. Estimates of dead salmon of all species 

 usually are very general, having been based on the 

 percentage of the count. 



Remarks. — Adjective ratings are given 

 first when available. The ratings range from poor 

 to excellent and describe the abundance of salmon 

 for the surveyed date only. They do not indicate 

 seasonal escapement abundance. Other notes
