Only 18 walleye tagged at other locations in the Yellowstone 

 were recaptured. Most of those tagged upstream from Intake dam 

 were recaptured at the same location or moved downstream (Table 

 17). 



Spawning Sites 



Haddix and Estes (1976) discovered that walleye and sauger 

 were spawning over an extensive gravel bar downstream from Intake 

 diversion during 1975 and 1976. Graham et al. 1979) also 

 documented that walleye and sauger were using this location for 

 reproduction in 1977. Graham et al. (1979) also sampled sites 

 downstream from Intake but found only one Stizostedion sp. egg. 

 One side of the Yellowstone was electrof ished from Forsyth to the 

 North Dakota border to find other spawning sites. 



The 84 km reach from Forsyth to Miles City was electrof ished 

 during May 2-3, 1979 and no spawning sites were found. Only 1 

 mature sauger and no walleye were collected. The reach from Miles 

 City to the North Dakota border was electrof ished from April 19 to 

 27, 1980. A total of 15 probable spawning sites for walleye were 

 identified; two upstream from Intake diversion and 13 downstream 

 (Figure 24) . A spawning area was identified by the presence of a 

 large number of males and the presence of eggs (Table 18) . The two 

 sites upstream from Intake diversion were both upstream from 

 Glendive, river km 163 and 154.
