REPORT OF COMMISSIONER OF FISH AND FISHERIES. XCV 



of fish-food found. It was learued that a considerable number of 

 salmon run into one or more of these lakes; and that all of them, but 

 particularly Whoahink, are well supplied with the native black-spotted 

 trout, which attains a large size and possesses excellent game qualities. 

 The planting of black bass in Tsiltcoos Lake would, in all probability, 

 prove detrimental to the native trout and the salmon, while the eastern 

 brook trout would probably never become so well established as to 

 render these lakes more attractive to anglers than they now are. 



UPPER KLAMATH LAKE, OREGON. 



In 1889 the Fish Commission planted 400,000 fry of the common 

 whitefish {Coregonvs clupeiformis) in Upper Klamath Lake. Sufficient 

 time having elapsed to enable the species to become established if the 

 conditions were favorable, investigations were made to determine the 

 result of the i)lant. ]\Iessrs. Meek and Alexander reached the lake 

 October 31, and continued their observations until iSTovember 7. The 

 parts of the lake which were most carefully examined wore Pelican Bay 

 and vicinity, and the extreme southern end, near Klamath Falls. The 

 lake was found to be comparatively shallow, the greatest depth in the 

 places where soundings were taken being 17 feet, while the usual depth 

 did not exceed 6 or 7 feet. The bottom consists largely of a loose layer 

 of decaying vegetation from the extensive tule marshes adjoining the 

 lake. Fish-food, chiefly small crustaceans and insect larvae, was found 

 to be very plentiful. Trials were made with seines, gill nets, set lines, 

 and other apparatus, but no whiteflsh were taken, nor did inquiry among 

 the people on the shores of the lakes elicit any information showing 

 that the fry have survived. The general physical characteristics of the 

 lake hardly warrant the expectation that the common whitefish can be 

 acclimatized. 



The lake is, however, well supplied with one of the largest and best 

 species of American trout. It attains a weight of 17 pounds and is 

 easily captured by trolling, and is so abundant as to attract many 

 anglers to the lake each season. The lake is also inhabited by four 

 or five s])ecies of suckers, several of which are exceedingly numerous, 

 of large size, and constitute an important part of the food supply of 

 the Indians upon the Klamath Eeservation. 



CRATER LAKE, OREGON. 



In response to the request of citizens of Klamath Falls, Ashland, 

 and Medford, Oreg., and of the Mazamas, an association of mountain 

 climbers with headcjuarters at Portland, Oreg., the Commission sent 

 Messrs. Evermann and Cox to Crater Lake to determine whether it 

 was advisable to plant trout in the lake, which now contains no fish 

 whatever. Six days in August were devoted to an examination of the 

 physical and biological features of the lake. 



This lake is on the crest of the Cascade Mountains, about 100 miles 

 east of Ashland. It is unique in character and ranks among the most
