small discontinuous pockets of gravel along 

 the edge of a small bluff on the east bank of 

 the river about 3.2 knn. above the mouth. 

 Surface velocity was 0.3-0.7 m./sec. in this 

 area. 



Chum salnnon, Oncorhynchus keta (Wal- 

 baurnJ.--Chum salmon were collected in the 

 Naknek and Shelikof Strait systems. They are 

 the least abundant salmon in the Naknek sys- 

 tem, and the only information on their occur- 

 rence and distribution is that some adults 

 (usually fewer than 10) pass through the 

 Brooks River weir each year; a few have been 

 reported in American Creek. We did not see 

 chum salmon in the Shelikof Strait area of the 

 monument, but they were reported in Big 

 River and in Katmai, Kuliak, Kaflia, Kukak, 

 Hallo, and Swikshak Bays, either in the early 

 U.S. Bureau of Fisheries management reports 

 or by biologists of Alaska Department of Fish 

 and Game. 



Coho salmon, Oncorhynchus kisutch (Wal- 

 baum) .--Coho salmon, which are widely dis- 

 tributed in the monument, were collected in 

 the Naknek, King Salmon, and Shelikof Strait 

 systems. Most of the information on this spe- 

 cies is based on samples of juveniles taken in 

 the summer because the adult salmon do not 

 appear until fall after much of the work on 

 sockeye salmon has been discontinued. Within 

 the Naknek system, annual counts of adult coho 

 salmon through Brooks River weir in 1957-62 

 ranged from 194 to 1,844 (average 620). We 

 collected juveniles or adult coho salmon inthe 

 Naknek system in Coville, Grosvenor, and 

 Brooks Rivers; Coville, Grosvenor, and Brooks 

 Lakes, and all basins of Naknek Lake; Hard- 

 scrabble, Margot, Headwater, Hidden, One 

 Shot, and West Creeks; and unnamed creeks 

 from Coville, Grosvenor, and lower Naknek 

 Lakes. The only coho salmon collected from 

 the King Salmon River system was a 62-mm. 

 juvenile from lower Cozy Lake on June 29, 

 1962. The only area where we saw coho salmon 

 along Shelikof Strait was in Big River; 71 ju- 

 veniles (35-68 mm.) were seined there on 

 August 15, 1964. Accounts of good runs of 

 adult coho salmon in Kaflia Bay lakes and 

 streams are given in some early management 

 reports. Although coho salmon have been 

 reported in Kashvik, Katmai, Kuliak, Kukak, 

 Hallo, and Kaguyak Bays and in Swikshak 

 Lagoon, they have not been reported from 

 streams that enter those waters. 



Sockeye salnnon, Oncorhynchus nerka (Wal- 



b a unn) .- -Sockeye salmon, the most evident and 

 widely distributed species in the monument, 

 were collected in the Naknek, King Salmon, 

 and Shelikof Strait systems. 



The Naknek system produces a large part of 

 the valuable Bristol Bay catch of this species; 

 annual escapements to the system have varied 

 between 0.3 and 2,2 million fish. The major 



spawning areas of sockeye salmon in the Nak. 

 nek system are the American, Hardscrabble, 

 Margot, Headwater, and Bay of Islands Creeks 

 and Grosvenor, Brooks, and Naknek Rivers. 

 Many smaller streams and some lake beaches 

 also support spawning populations. Juvenile 

 sockeye salmon occurred in all areas of the 

 larger Naknek systenn lakes except Idavain 

 and Murray Lakes, Sport fishing for adults is 

 popular in Brooks River. 



No fresh-water (kokanee) populations of 

 sockeye salmon are known to occur sympatri- 

 cally with anadromous populations in the 

 monument. We discovered kokanee salmon in 

 two lakes that drain into Shelikof Strait, and 

 Greenbank (see footnote 4) reported thenn in 

 Jo-Jo Lake. 



We saw several schools of young-of-the- 

 year sockeye salmon (age 0) in lower Cozy 

 Lake of the King Salmon River system and 

 collected about 100 fish on June 29, 1962. 



Apparently the largest run of anadromous 

 sockeye salnnon in the Shelikof Strait area of 

 the monument is into two lakes at the head of 

 Kaflia Bay. The lower lake has slightly brack- 

 ish water either from seepage or possibly 

 from flooding on extremely high tides. The 

 upper lake is 15 to 23 m. higher than the 

 lower, and the two are connected by a steep 

 boulder-strewn stream about 305 m, long. 

 The U.S. Bureau of Fisheries had a weir for 

 counting adult salmon, presumably at the out- 

 let of the lower lake at Kaflia Bay in 1929-32, 

 and 1934; escapements of spawning sockeye 

 salmon into the two lakes in these years aver- 

 aged about 12,500 (see footnote 5), The esti- 

 mated escapement of sockeye salmon to the 

 two lakes in 1939 was 100,000 fish. On July 12, 

 1963, we saw about 2,000 adult sockeye salmon 

 off the mouth of the interconnecting stream 

 between the two lakes. We saw no adult salmon 

 in the stream proper, but collected one juve- 

 nile (about 70 mm, long) from a pool just 

 below the upper lake, so at least sonne adults 

 ascend this precipitous stream, 



Sockeye salnnon runs of unknown size were 

 reported in the early management reports and 

 by local residents of the Kodiak Island area to 

 occur in a small lake at the head of the west 

 arm of Kuliak Bay (known locally as Halferty 

 Bay), We saw no adults on two collecting trips 

 to the Kuliak Bay Lake in August 1964, but 

 collected several juveniles (age and 1; from 

 52 to 92 mm,). The outlet stream had no bar- 

 riers or obstructions that would prevent anad- 

 romous adults from entering the lake. 



We collected juvenile sockeye salmon in 1962 

 from Dakavak Lake and a small lake above 

 the Devils Cove portion of Kukak Bay. No rec- 

 ords of adult sockeye salnnon have been found 

 in the commercial statistics for the bays 

 into which these lakes drain. Moreover, the 

 streams flowing from these lakes have bar- 

 riers, and we believe that the populations in 

 both lakes are landlocked kokanee salmon.
