THIN POINT LAGOON SALMON COUNT 
Salmon counting was inaugurated in 1926 at Thin Point Lagoon 
by the construction of a weir at the lake outlet above the lagoon. 
Considerable trouble was experienced in finding a suitable site on 
account of the short course of the stream that flows from the lake 
into the lagoon. The site selected was in the lake itself, where a 
V-shaped weir, about 150 feet long, was erected, the ends: touching 
the lake shore and extending out into the lake. It was protected by 
a small point that extends “into the lake. The water was shallow, 
from 6 to 30 inches, except in one deeper hole, and the current was 
sluggish, except in a northeasterly wind. During the season the

extremely warm weather melted Frosty Peak Glacier to such an 
extent that the stream flowing from it broke a new channel into Thin 
Point Lake and deposited a considerable amount of sediment at the 
outlet and along the left shore lead of the weir. No damage was 
done to the weir, but the resulting discoloration made it difficult to 
see and count the salmon. 
The weir was completed by July 1, and the first red salmon were 
counted through on July 10, the last on August 28. The total 
escapement counted was 8 ere 72 reds and 57 cohos. Some cohos were 
still in the lagoon when the weir was removed on September 1 and 
would probably ascend later. The escapement was regarded as poor 
as compared with other years. Many fish perished on the flats, due, 
it is thought, to the low water and the silt from the glacial stream, 
which clogged their gills. 
The work at this place was under the supervision of Assistant 
Agent L. G. Wingard.
