1. Survey of the Fisheries Resource of the Colorado River (Now FA: F-2-R). 



A basic data survey of the Lower Colorado River Fisheries Resource has been 



completed. The recreational value of the fishery and the species of fish present, 

 their relative abundance and food supply, were the major objectives of the project. 

 A management and development plan for the Colorado River has been instituted. 

 Research is being continued on problems that are evident as a result of the basic 

 data survey.

2. Luna Lake Development Project (FA: FW-2-D). 



The height of Luna Lake Dam has been increased to insure permanent dead water 

 storage for fish and waterfowl. A permanent dead storage of 550 acre-feet 

 covering 67 surface acres was created through this project. A total storage of 

 1, 390 acre-feet covering 151 surface acres was developed. 



Apache County; completed in 1952; $47,512 total cost.

3. Rough Fish Control. 



Lyman Reservoir, Kinnikinick and Becker Lake were poisoned with toxaphene for 

 the eradication of rough fish. Toxaphene was applied at the rate of 0.1 ppm at 

 temperatures ranging from 52 to 79° Fahrenheit. In the latter two lakes, a 100 

 percent kill of ail fish life was accomplished. The lakes were suitable for re- 

 stocking six weeks after the date of treatment. Cost of treatment averaged 

 $0.18 per acre-foot. 



Apache and Coconino Counties; completed in 1952.

4. Basic Data Fisheries Research of the Lakes of Anderson Mesa (FA: FW-l-R). 



Anderson Mesa is located in Central Arizona at a general elevation of 7, 000 feet. 

 This project was instituted to gain basic data upon which to base a comprehen- 

 sive fisheries management program for the seven lakes of Anderson Mesa; a 

 complete limnological and fish population survey constituted the major work of 

 this project.
