Growth during the first year in the reservoir appears to be directly 

 related to the planting time (Figure 6). The trout planted in April and 

 May (1972) displayed greater growth than those planted in June, July or 

 August (1970, 1971). Seven months following introduction, the trout planted 

 1n April and May, 1975 averaged 14.3 inches, about 4 inches longer than 

 rainbow trout planted for the same duration in 1970. During the second 

 year in the reservoir, the greatest variation between years is about 1.5 

 inches while during the third year there is very little difference. 



During the study, storage in the reservoir varied greatly between years 

 (Figure 1). Growth of hatchery rainbow trout did not appear to be related 

 to either the maximum or minimum storage pools. 

 Fishing Pressure 



In 1971 and 1972, an intensive creel census was conducted. Ice fishing 

 data were included with the data for bank fishing. Although some ice fisher- 

 men were fishing with the intent of catching burbot, trout were kept when 

 caught. 



Fishing pressure in 1971 for bank and boat fishing was 53,241 and 

 60,201 fisherman hours, respectively, and for 1972, 67,631 and 67,939 

 fisherman hours, respectively. Total fishing pressure increased about 20% 

 between 1971 and 1972. Bank fishing increased 27% while boat fishing in- 

 creased 16%. The greatest increase in bank fishing occurred during the 

 weekdays (49%). The greatest increase in boat fishing occurred on the 

 weekends (16%) 



The estimated number of fisherman days for 1971 was 30,400 and 

 36,000 for 1972. Most fishermen had not completed fishing when contacted.
