Klutina, located midway between, is intermediate in size. The 

 lakes are alike in being crescentic in form, surrounded, at least 

 in part, by mountains and fed by the run-off of great glaciers. 

 The two larger lakes are 20 to 30 miles long and 5 to 6 miles 

 in maximum breadth. The upper horn of the crescent points 

 pretty nearly east and gives rise to a stream which is the out- 

 let of the lake. The other horn points nearly straight south 

 into the mountains and is in connection with large glaciers. 

 Each lake has several lateral tributaries. In each case certain 

 of these tributaries carry salmon and afford spawning grounds 

 for them, whereas others are without these fish. A stream 

 known as Saint Anne Creek enters Klutina Lake from the 

 northwest. This stream was visited twice during our stay in 

 that region. 



Our visits fell fortunately at times that yielded important 

 results for the general problem under discussion. Saint Anne 

 Creek is a small stream which enters from the northwest ap- 

 proximately at the center of the outer curve of the crescent 

 of Lake Klutina. It drains a considerable body of shallow 

 water known as Saint Anne Lake, which is located about six 

 or eight miles from Lake Klutina and is about four miles long 

 by one mile wide. The stream has a gentle fall over a gravelly 

 bottom without rapids or serious obstructions. While the 

 depth does not vary greatly, the creek forms a succession of 

 small curves, in the elbow of which a deeper, more quiet area 

 alternates with the shallower, swifter stretches connecting the 

 quiet pools. 



We first visited this creek on August 10, passing up through 

 the stream bed a distance of three miles or more. A large 

 number of spawning fish were seen. The shallow stretches 

 along the inside of the curves made by the stream were cov- 

 ered with dead fish. While many of these fish had been par- 

 tially eaten by bears, the majority of them were relatively 

 fresh. 



This stream has a broad and shallow delta in front of it, 

 so that the water spreads out widely before coming in contact
