in southeastern New Hampshire. Essentially the same results were obtained for 

 this eastern basin as for the Ashuelot River basin. This was due to many 

 similarities between the two basins. Both analyses used the same prices and 

 technical information. Constraints were changed to reflect economic activity in 

 the Lamprey River basin and the inter-basin transfer of water from the Lamprey 

 to the Oyster River. Variation in river flow has a greater effect on resource use 

 than quantity of water transferred. 



Major Conclusions 



1. The application of linear programming models to water-related activities on a 

 river-basin basis is a valid and useful means of assessing the impact of changes 

 in certain variables and planning objectives on optimum resource allocation. 

 Toward this end, the linear programming capabilities for shadow pricing and 

 sensitivity analysis are quite effective. The results appear to be indicative of 

 real-world situations, and the model is adaptable to other river basins with a 

 relatively small amount of additional modeling input; most changes involve 

 adaptation of constraints to new conditions. 



2. The study clearly pointed out the advantages, even the necessity, of integrated 

 planning for water-resource development and use on a regional or river-basin 

 basis. Economic efficiency as well as environmental quality are enhanced 

 through combined planning and development. 



3. The study identified economic conflicts that occur in choosing among water- 

 use and -development alternatives. These conflicts must be identified before 

 good choices can be made. 



4. The analyses carried out in the study pointed out the difficulty of meeting 

 certain environmental goals unless adequate economic and technological 

 planning is done very soon.
