SALMON AND TROUT IK ALASKA.

Lake. Their most prolific grounds are that section of the main river 

 between the lagoon and Jordan Lake, a large area being afforded by 

 the stream just below and immediately above Dorr Falls. In addi- 

 tion they occupy the many small creeks which enter the lagoon, the 

 river, and the lakes. King and dog salmon enter the Naha in too 

 small numbers to indicate their preferences, but king salmon have 

 been seined at the hatchery, and it is probable that in all such streams 

 they go as far upstream as possible. But one king salmon fry was 

 taken during the present work, that from the lower river on June 

 11, 1903. A few dog-salmon fry were noted migrating from Gibson 

 Creek. They formed a scarcely notable percentage in the catches in 

 the main stream. 



A considerable part of the shores of both Heckman and Jordan 

 lakes is of gravel and apparently not unsuitable for "nests." It 

 may be that when the stream was crowded the shores were used, but 

 at no time were sockeyes observed to spawn about the lake shores 

 as in other basins. The portion of the stream between these two 

 lakes was not inspected, but the area of suitable ground for beds is 

 said to be small, the channel being very rough. A few cohos spawn 

 just above Jordan Lake, but inspection by the hatchery superintend- 

 ent has shown that the sockeyes do not frequent this section of the 

 river. 



YIELD OF SALMON. 



As a sockeye stream the Naha has been one of the most productive 

 of the smaller streams of Southeast Alaska, a fact which may be due 

 in part to its having been so unremittingly fished. The long, narrow 

 bay which receives the river furnished excellent fishing grounds, and 

 the shallow upper end an excellent foundation for a fence. In the 

 following table is shown in round numbers the yield of the Naha 

 and the important adjacent streams for each year from 1887 to 1900:
