In the area bordering the Upper Sacraraento River, bounded by Redding; 

 to the north and Chico and Orland to the south, 38 establishments other 

 than boat landings carried complete stocks of fishing; tackle and equipment 

 at the close of 1948. Twenty-three of these establishments sold outboard 

 motors and 12 sold boats to fishermeno The gross sales of tackle, equip- 

 ment, boats and motors in this area during 1948 was |435,000. Forty-five 

 employees devoted all or part of their time to sales of fishinf equipment 

 expendinn; an estimated 201 rian months of labor during 1948. Fishing equip- 

 ment sold in this area but not used on the river was probably more than 

 compensated for by tackle sold outside the area and used for river fishing. 

 Nearly half of the fishermen on the river originate from outside the area 

 and purchase their majoi items of fishinr equipment in their home towns. 

 Thus the above value can be attributed to the river fishery. 



In summary, there were a total of 46 establishments receiving ma^ior 

 benefits from the sports fishery during 1948, There were 67 full and part- 

 time employees who derived all or part of their income from work 3n boat 

 rentals or tackle shops* The gross income for all establishments during 

 1948 was $475,200o At 4 percent this represents an #11,880,000 investment 

 in the sports fishery of the Upper Sacramento River* 



SUMMARY 



1, Changes in the environmental conditions of the Upper Sacramento 

 River following the construction of Shasta Dam have resulted in marked 

 changes in game fish populations* An investigation was initiated in 

 August, 1947, to learn how these changes have influenced the sports 

 fishery* 



2* Before the construction of Shasta Dam, the Upper Sacramento 

 River was a warm-water river o The most common game fish foiand in 

 order of their probable importance were the striped bass, catfish, 

 largemouth bass, bluegill, Sacramento perch, shad, Sacramento sucker, 

 carp and Sacramento squawfish* King salmon and steelhead trout pro- 

 duced seasonal fisheries in fall and winter months* 



3* Increased summer flows released from sub-thermocline depths 

 of Shasta Reservoir changed the Upper Sacramento to a oold'-water river* 

 Adult and young salmon are year-round residents in the upper river, 

 as are the rainbow and steelhead trouto These species now produce 

 continuous sports fisheries* Game fish of lesser importance since 

 operation of Shasta Dam began, in order of their importance, are the 

 striped bass, catfish, shad, Sacramento squaYrfish, Sacramento sucker, 

 carp and smallmouth and largemouth bass*
