Transfer of the salmon to Deer Creek was made by means of specially 

 built tank trucks^ each of which had a capacity of 1,000 gallons. Total 

 distance of the haul was about 6o miles and required from 2-1/2 to 3 hours 

 to accomplish^ The number of salmon per truck load ranged generally from 

 20 to 50., with an average load comprising 39 adults. The trucks were 

 eqvdpped with aerators and, while en route^ t-he water in the truck tank 

 was maintained at a temperature approximating 50 degrees Fahrenheit by 

 circulating a portion of the water through a compartment filled with ice. 

 When the trucks reached Deer Creek, the tank water was slowly tempered by 

 pumping water from the creek into the tank. The fish were released when 

 the water temperature in the tank was within 2 or 3 degrees of that in 

 the creek o 



Yearly Counts at Deer Greek Weir 



Early in the investigations of the Shasta problem, the importance 

 and necessity of knowing the size of the native salmon population was 

 realized. With the advent of salmon transfers to Deer Creek^ the value 

 of such information was greatly increased. In 19iiO, a partial salmon count 

 was obtained at the dam of the Deer Creek Irrigation Company at the mouth 

 of the canyon. Since then, all co'onts have been made at the Deer Creek 

 weir. 



Periods of counting have not been uniform. Varying stream flows and 

 run-off patterns determined the time of weir installation, and water tempera- 

 tures regulated the termination of counting. It has often been necessary, 

 because of floods, to remove the weir for varying periods of time during 

 the counting season. The counts, therefore, are not complete. 



End of the spring-run count in Deer Creek each year is always brought 

 about by two conditions s (1) lack of sufficient water below irrigation 

 diversions for the salmon to ascend readily, and (2) onset of high water 

 temperatures which finally become lethal to salmon. 



Counting of the fall-run salmon has not been attempted because of 

 unpredictable stream flows which are either insiifficient for mj.gration or 

 so high as to endanger the weir during this normally rainy season. 



The yearly counts of salmon at Deer Creek, periods of comiting, peak 

 months or periods, and losses of salmon below the weir because of the 

 onset of lethal temperatures are presented in table 2.
