eliminated. Forsyth diversion may inhibit sauger from proceeding 



further upstream. Tag returns and size structure of the population 



upstream from Forsyth diversion indicate that mostly larger 



individuals negotiated this structure. 



Estimates of the sauger populations for an 8 km reach of the 



Yellowstone River at Miles City (river km 298) during fall of 1978, 



1979, and 1980 was 1981, 1416, and 1809 fish, respectively. These 



estimates as well as other related population statistics can be 



used to monitor any changes in the sauger population.
