1 to 4 inches stretched measure. Sets were made overnight and the nets 

 were hauled in each morning. The fish were measured, and a sample of 

 each species was saved for purposes of identification. 



Table 8 shows the results of fishing both at the surface and at 

 the bottom. In 21 net-nights of fishing on the bottom, there was an 

 average catch of 7.4 fish per net-night, and in 9 net nights of fishing 

 at the surface 7.3 fish were caught per net-night. The largest single 

 haul consisted of 28 fish taken in 6 feet of water at a point one mile 

 above the mouth of the San Foil River. All fish appeared in good 

 condition although tapeworms were found in some of the squawfish and 

 chubs. Sizes of fish caught are shown in Table 9. Larger squawfish 

 and suckers weighed as much as two pounds • 



The most numerous fish in the samples were squawfish, which ac- 

 counted for 60 percent of the catch. Chubs were next in abundance, 

 comprising 22 percent of the catch. More chubs were caught near the 

 STirface than at the bottom. 



While the ssunpling might indicate that the squawfish was the 

 predcaainant species in the lake, it is believed that the carp is 

 more abundant* Carp apparently do not readily gill as the only carp 

 caught was snagged by the barbs in its dorsal spine. The Washington 

 State Department of Game seined 50 tons of carp in 1947 and 100 tons 

 in 1948 from Roosevelt Lake. These were taken near the mouth of the 

 Kettle River and near the town of Marble and were used for hatchery 

 food. 



Numerous carp were seen in the lower portion of the Kettle River 

 during August and September. They form spawning schools in the 

 shallow slough areas during the spring and early summer months, at 

 which time they are easily taken in seines. 



Sport Fishing 



Some information on the fish population of the lake was obtained 

 from local sportsmen. In addition to those species mentioned in 

 Table 9, sportsmen reported having caught the following; 



1» Rainbow trout, Salmo gairdnerii 

 2, Brook trout, Salvelinus fontinalis 

 5« Whitefish, Pros opium coulteri, 



Prosopium williamsoni . Pros opium oregoniiaa 

 4* Kokanee (landlocked sockeye salmon), Qncorhynohus nerka kennerlyi 

 5* Kamloops trout, Salmo gairdnerii kamloops
