9 May 1976 - Sand 

 and pebble beach 

 decreases in width 

 from the profile 

 line to the south.

12 August 1974 - Beach is almost 

 nonexistent due to high summer 

 lake level. 



Profile Line 2. Very steep sand bluff with active erosion below the 8.3-meter 

 contour. Bluff above this contour is well vegetated. Wide range of sand and 

 gravel (almost no silt) found on beach. Bluff relatively stable during Davis 

 (1976) surveys with the greatest amount of retreat, 3.4 meters, occurring 

 after November 1973. Beach also relatively stable between October 1973 and 

 December 1974. The stability of this profile line is perplexing. Davis, 

 Fingleton, and Pritchett (1975) reported that nearby areas had severely 

 eroded.
