64 PACIFIC SALMON FISHERIES. 
large run comes the following method is employed: An actual tally 
of every salmon passing through is made for one minute, and this is 
repeated 15 minutes later, the number passing through for one minute 
being regarded as the average for 15 minutes. A sheet with the whole 
day divided into quarter hours is kept ready at the gate and the 
number for one minute as taken from the tally register is immediately 
entered thereon by the attendant who made the tally. From these 
figures the total for the day is obtained. During only a small part 
of the season has it been found necessary to resort to this method of 
estimating the run. : 
The following table shows for each year since 1908 the commercial 
catch of salmon made in Nushagak Bay, the number of fish passing 
from Wood River into Lake Aleknagik, the total of both and the per- 
centage of salmon that escaped the fishermen:

Snake River, a tributary of Nushagak Bay, is about 30 miles in 
length, very crooked, and has its rise in a single lake close by Alekna- 
gik Lake. ‘There is an Indian village on the river just below the lake. 
Red salmon are abundant in this stream. 
Igushik River is about 50 miles in length and enters Nushagak Bay 
about 4 miles above Nichols Hills. So far as known it has its source 
in two lakes—Amanka and Ualik. A short distance below the first 
lake there are rapids and a small falls. The quite large Indian village 
of Yacherk is located here, and the natives do most of their fishing in 
the rapids. Peter M. Nelson established a saltery about 10 or 12 
miles above its mouth in 1902, and operated it until he sold it to the 
Alaska Fishermen’s Packing Co., who have operated it since. There 
is a small Indian village close by the saltery. 
Nushagak Bay, in which practically all the fishing is carried on, 
is about 35 miles long and from 5 to 15 miles wide. Sand bars 
and mud flats, which are visible at low water, occupy the greater 
part of its area. 
The drift gill net is the favorite apparatus in this bay, although a 
few traps are also used. The fish begin to run very early here. 
Kings usually appear about June 5, reds about June 5 to 8, cohos 
appear either late in June or early in July, chum salmon about the 
middle of June, and humpbacks about the same time.
