1. Grebe Lake Studies 



The objective is to determine the best management practices for the wel- 

 fare of grayling in Grebe Lake. The presence of trout, egg-taking, and 

 angling are factors which complicate the problem. Studies have centered 

 around measurements and counts of survival and mortality at all life history 

 stages.
