3. Effect of Logging on Water Yield and Erosion in the Douglas -Fir Region. 



Objectives of the project are to determine the effects of logging and con- 

 struction of hauling roads in an old-growth Douglas-fir forest on water yields, 

 water temperatures, and sedimentation. Stream gages have been installed in 

 three experimental watersheds (180, 240, and 260 acres). Two types of cutting 

 treatments will be tested on two drainages by comparison with the third, an 

 undisburbed area. Pretreatment behavior of streamflow, necessary to evaluate 

 final results, is now being measured.

2. Technical Assistance in Fish Cultural Activities. 



Assistance is given to fish cultural personnel toward the solution of bio- 

 logical problems of hatchery management, such as weed control, fertilization, 

 disease, and water quality; and in initiating new or improved techniques. Fish 

 stocking activities are reviewed for correlation with State Conservation Depart- 

 ment practices and to direct the distribution of Federally produced fish in accord- 

 ance with Fish and Wildlife Service policy and known fishery management needs.

1. Rogue River Investigations. 



This project was initiated to determine the possible effect of proposed water 

 developments on fish and wldlife of the Rogue River and its tributaries. Infor- 

 mation is gathered on catch and spawning distribution of both resident and 

 anadromous species of salmon and trout.
