I = Iliamna Lake; G = Gibraltar 

 lake; C = Lake Clark; and K = ICijik 

 lake. 



Stream niomber . — The stream 

 designation in the upper lei1:-hand 

 corner of each page consists of a let- 

 ter followed by a number. The letter 

 designates the lake into which the 

 stream flows or from which it originates 

 (connecting streams between lakes). The 

 number represents the distance in miles 

 and tenths of a mile of the stream 

 mouth (or beach, as the case may be) 

 from the outlet of the lake measured 

 along the shoreline in a clockwise dir- 

 ection. The measurement is to the 

 center of the stream mouth (or beach). 



A tributary of the trunk 

 stream is designated by a number sep- 

 arated from the stream niimber by a 

 colon. The number represents the dis- 

 tance in miles and tenths of a mile of 

 the tributary from the origin of the 

 trunk stream. The "R" or "L" after the 

 tribiitary nvunber indicates whether the 

 stream enters from the right or left of 

 the trunk stream (f8,cing domstream) . 



lakeshore beaches have the 

 same designation as streams. An is- 

 land beach is designated in a different 

 fashion. The number following the lake 

 designation represents the mileage in a 

 straight line from the outlet of the 

 lake to the northernincst (true north) 

 point of land. This is followed by a 

 colon, "l" (for island), and a number 

 representing the e:d;ent of the spawn- 

 ing beach, which is in miles and tenths 

 of a mile in a cloclcid.se direction 

 around the island from the northernmost 

 point . 



Lake letter designations used 

 in this catalog are as follows: 



Stream name . — The name is 

 at the center top of each page. 

 The lake or river system of which 

 the spawning area is part follows 

 the stream name in parentheses . 

 Names from U.S.G.S. maps are used ;4iai 

 available, otherwise local names 

 are used. 



Location. — The north lat- 



itude (N.) and west longitude (w.) 

 are given for each stream, pond, 

 or beach in degrees ( ), minutes 

 ('), and seconds ("). For lakes, 

 the latitude and longitude of the 

 o\xtlet are given.
