Figure 2.— Katmal National Monument, showing principal fresh-water areas. Asterisks indicate general locations where 

 fish collections were made in the King Salmon River system and along Shelikof Strait, 1962-64. Hundreds of collections 

 have been made throughout the Naknek River system beginning originally at Brooks Lake in 1940. Kuliak Bay Lake, 

 Kaflia Bay Lake, Devils Cove Lake, Hallo Glacier Lake, Katmai Crater Lake, and Kaguyak Crater Lake are not offi- 

 cial names. They are identified as such in this manuscript with nearby named geographic features for convenience 

 only. 



FRESH-WATER AREAS OF THE MONUMENT 



The most important drainage feature of the 

 monument is the arrangement of the Aleutian 

 Range so that streams along the west side of 

 the Alaska Peninsula flow into the Bering Sea 

 through Bristol Bay and streams along the 

 east side flow into the North Pacific Ocean 

 through Shelikof Strait or Cook Inlet (fig. 1), 

 A second important feature is the number, 

 size, and relative complexity of drainage 

 systems along the east and west sides of the 

 monument (fig. 2). Although no major zoogeo- 

 graphical barriers lie between stream sys- 

 tems draining into Bristol Bay and interior 

 Alaska, streams flowing into Shelikof Strait 



are essentially isolated from other fresh 

 waters of the continent by the Aleutian Range. 



BRISTOL BAY DRAINAGE 



The principal fresh-water areas in the 

 monument that drain into Bristol Bay are in 

 the Naknek and King Salmon River systems. 

 Of minor importance are the extreme head- 

 waters of the Kejulik River in the Egegik 

 River system, which lie just inside the south- 

 ern boundary of the monument. These head- 

 waters are small and of little significance to 

 the distribution of fish in the monument (fig, 2),
