Scott and Grossman (1973), and Hogue et al. (1976) were used to 

 identify eggs and larvae of sauger and walleye. 



To determine late summer-fall distribution and abundance of 

 young-of-year through adult sauger and walleye, 15 stations were 

 electrof ished during this time period from Huntley (river km 566) 

 to Sidney (river km 56) (Figure 3) . The stations were: 1) 

 downstream from Huntley irrigation diversion, 2) near the mouth of 

 the Bighorn River 3) the Bighorn River from a diversion dam to the 

 mouth, 4) near Hysham downstream from an irrigation diversion, 5) 

 upstream from Forsyth diversion, 6) downstream from Forsyth 

 diversion, 7) near Hathaway, 8) near the mouth of the Tongue River, 

 9) 21 km downstream from the Tongue River, 10) near the mouth of 

 the Powder River, 11) near Fallon, 12) near Hoyt (river km 192) , 

 13) near Glendive, 14) downstream from Intake diversion, 15) near 

 Savage, and 16) near Sidney. Each of these stations were 

 approximately 8 km in length (except the Bighorn River station 

 which was 4.8 km) and both sides were sampled. Catch rates were 

 expressed as the number of fish captured per river kilometer (both 

 sides) sampled. These stations were lumped into 4 river sections 

 Figure 3) and data computed accordingly. 



Movement of fish was determined by recapturing tagged fish 

 with electrof ishing gear or receiving voluntary returns from 

 fishermen. Tag return analysis by season and location was aided 

 with a computer program (Graham et al. 1980). A difference of at
