Table 1. --Estimated densities of 1961 brood year salmon eggs and larvae in 

 Sashin Creek study area before deposition of 1962 brood year eggs 



— Based on estimated potential egg deposition. 



_' Estimates obtained by pooling data from two areas lying outside the boundaries 

 of the study area (one upstream and the other downstream). They are assumed to be 

 representative of the study area, since the potential egg deposition was estimated to 

 be nearly the same over all of the Sashin Creek spawning ground and since estimates 

 of total egg density within each of the two areas did not differ significantly.
