Cold-water Reservoirs 



Deerfield Reservoir , South Dakota (5, lh), ^35 acres in size, is on 

 Castle Creek in the center of the Black Hills. Completed in 1915, the reservoir 

 was constructed to provide storage and regulation of water for irrigation and 

 municipal use. Fluctuations had not exceeded 6 feet prior to the 19f>0 study. 

 This reservoir is somewhat unusual in that aquatic vegetation occurred in most 

 of the shallow areas. 



Access to the area is moderately good during dry weather. Fishermen 

 came largely from within a radius of $0 miles. The species most commonly repre- 

 sented in the creels were, in order of abundance, rainbow trout, white sucker, 

 brown trout, and brook trout. Mountain suckers and green sunfish also were taken. 



Type and period of coverage! Intensive checks, May 1 through Septem- 

 ber 30, 19U9 and 195^. 



Period of estimates: Estimates of use and yield for above periods — 

 the fishing season. 



Expenditures for eqtiipment and annual items: Obtained in field in 19 u9. 



Other expenditure items: Obtained in 1950, combined with equipment and 

 annual expenditures, and applied to both years. 



Pathfinder Reservoir , Wyoming (10), was completed in 1909. It is on the 

 North Platte River in the south-central part of Wyoming and provides storage for 

 irrigation and power. The reservoir fluctuated about ti3 feet during the period 

 of study. It has a surface area of 22,600 acres.
