State about 7 miles south of the city of North Platte. It is an off -stream 

 regulatory reservoir of 1,670 surface acres, built for storage and regulation 

 of irrigation water and production of power. Maximum depth is about 31 feet. 

 The annual fluctuation did not exceed 5 feet during the 2-year study. 



Access to the area is excellent by a direct road from the city of 

 North Platte. Approximately 97 percent of the fishermen contacted were resi- 

 dents of Nebraska, of which 8U percent came from the town of North Platte.

 September lii, 19U8, and April 23 through September It, 19li9. Limited checks 

 during the fall and winter. 



Periods of estimates: Estimates of use and yield for entire year 

 in both 19h8 and 19h9. 



Expenditures for equipment and annual items: Obtained in the field. 



Other expenditure items: Obtained in summer of 19lj9 only but applied 

 throughout both years. 



Fort Peck Reservoir , Montana (9), completed in 1939, is on the Missouri 

 River in northeastern Montana. This 2lp5,000-acre reservoir was built to provide 

 storage of water for navigation, flood control, irrigation, and production of 

 hydroelectric power. The greatest depth is 225 feet. Water levels fluctuated 

 about 20 feet during the period of study. Access to the reservoir is good only 

 in the vicinity of the dam; elsewhere, roads are generally poor or nonexistent. 

 More than 80 percent of the fishermen came from within a 50-mile radius.
