Geadient. --Estimates in degrees from hori- 
zontal, based on observation by various individuals. 
Velocity. ~-Estimates in feet per second dur- 
ing normal water levels, based on observation by 
various individuals. 
Bottom. --A description is given of the com~ 
position such as gravel (range from 1/4 inch to over 5 
inches in diameter, arbitrary division point), mud, 
silt, organic materials, broken and water-washed 
rock, boulders, large rocks, bedrock, etc., according 
to observations by various individuals. 
Low tide location. --The location of the 
mean low tide point is an approximation and is given 
only where it falls near good identification points, 
usually found in restricted stream outlets. 
High tide location. -- The mean high tide 
location generally has been found to correspond to the 
tree line. Other methods of locating the high tides, 
such as markers, are described when present. 
Salmon schooling areas. --The areas are 
usually found near high tide where pools often occur. 
The areas are described with reference to the mean 
high tide mark. Annual variations in stream beds may 
alter locations of schooling areas. 
Spawning areas. ~-Major areas are described 
with reference to the high tide mark. Location may 
change with change in stream conditions. 
General notes. --This includes notes per- 
tinent to the intertidal stream that are of interest and 
importance in the description of runs. 
Upstream 
Length accessible. --The length given in 
miles was measured from aerial photographs along the 
course of the stream to the known upper limits of 
salmon migration. Where barriers restrict major 
species but allow more vigorous species to pass, sec- 
ondary species limits are given under "Barriers", 
Gradient. --Slope was estimated in degrees 
from horizontal, based on observation by various indi- 
viduals. 
Velocity. --It is in feet per second during 
normal water levels, and is an estimate from obser- 
vations by various individuals. 
Bottom. --A description is given as to wheth- 
er gravel (range from 1/4 inch to over 5 inches in dia- 
meter, arbitrary division point), mud, silt, organic 
materials, broken and water-washed rock, boulders, 
bedrock, etc., are present, from observations by vari- 
ous individuals. 
Marker distance. --Distance is given in 
miles along stream course to standard termination 
point for salmon counting. 
Marker identification. -- Description of an 
artificial marker or of identification feature marking 
termination point for salmon spawning surveys is given. 
Barriers. -- Distance and location above 
high tide point to known barriers, both passable and 
impassable, are listed. Descriptions are also given 
when available. 
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. 
Escapement Record 
Statistical area number. --The number used 
by the Bureau of Commercial Fisheries to designate 
the statistical area is given in the upper left side of 
the heading, 
Stream name. -- This appears in the center 
of the first line of the heading. 
Stream number, -- The new and old num- 
bers appear on the right side of the first line of the 
heading on the first page of the escapement record. 
The following pages give only the new number. 

Date surveyed. ~-Surveys are listed chron- 
ologically. 
Miles surveyed. --Distances are given as 
measured along stream course to the termination 
point of the regular survey. Ground surveys are des- 
ignated by "G" and aerial by "A". These symbols 
precede miles surveyed. 
Surveyed by. --Initials of surveying 
organizations are listed as follows: Alaska Department 
of Fish and Game, ADF; Alaska Salmon Industry, 
ASI; Fisheries Research Institute, FRI; U.S. Fish and
