What Is in the Future? 13 



movement continues to l:)oom witli recreational uses sharing equally with 

 those of water supply. 



Many communities still have inadequate water supplies for their resi- 

 dents and for commercial developments. Others that have adequate water 

 today will find they need supplemental water sources in the future. Thus 

 within the near future, most of the available small sites for artificial 

 impoundments in the more thickly populated sections of the country 

 will be in use. In most instances these water-supply reservoirs will be 

 available for public recreation. 



The U.S. Corps of Army Engineers has created reservoirs or has plans 

 for impoundments on nearly every stream in the United States with any 

 record of primary or secondary flood damage. Many of these planned 

 reser\'oirs may not be built within the immediate future, but enough will 

 be authorized to spread a network of reservoirs throughout the drainage 

 basins of all major rivers. These reservoirs will be created primarily for 

 flood control, but nearly all will have conservation pools that will be used 

 extensively for aquatic recreation. 



As hunting becomes progressively more restricted and localized, op- 

 portunities for fishing will continue to increase and become more widely 

 distributed. The development of management methods for impoundments 

 will be intensified, but along lines of greater sport production, rather than 

 for the production of fish for food. 



In the following chapters I have detailed the known characteristics and 

 dynamic processes of warm-water fish populations. These must be thor- 

 oughly understood and appreciated before one can apply management. 

 While the principles of warm-water populations are broad, any applica- 

 tion to a selected population is specific, and hence requires understanding 

 not only of these general principles but also of all the ramifications of a 

 current situation.
