Upper Snake River Basin Storage Optimization Study 



The Upper Snake River Basin Storage Optimization Study is evaluating 

 alternative operational scenarios for existing storage reservoirs. 

 The Upper Snake River Basin Storage Optimization Study will develop and 

 evaluate alternative operational scenarios for the storage reservoirs in the 

 Upper Snake River Basin. Existing Federal reservoirs include American Falls. 

 Grassy Lake. Island Park. Jackson Lake. Lake Walcott. Palisades, and Rine. 

 Total active storage capacity is about 4 million acre-feet. Reclamation is 

 cooperating with the State of Idaho and others in this project. 



Competition for the water supplies of the upper Snake River basin is becoming 

 more pronounced. Opportunities for the potential transfer or marketing of 

 water supplies are beginning to surface. The available water resources appear 

 to have the capability to assist in meeting additional needs provided that 

 appropriate technical and institutional vehicles for broader use can be 

 formulated. 



Reclamation and the State of Idaho are also interested in assessing 

 development limits and constraints resulting from the 1984 Snake River water 

 rights agreement (Swan Falls agreement), as well as developing an improved 

 water management plan for the upper Snake River basin. 



This study is in large part designed to build on and extend previous 

 hydrologic studies, both surface and groundwater, conducted by the Idaho 

 Department of Water Resources. Reclamation, and other agencies. The study 

 will evaluate several conceptual uses of the water resources of the upper 

 Snake River basin while recognizing existing water rights and entitlements. 

 The study is addressing a number of options that would make the operation of 

 Reclamation and non-Federal water regulation facilities more flexible in the 

 upper Snake River basin to meet the many competing demands placed on this 

 water source. 



Current Status 



Ongoing efforts in gathering cropping and irrigated acreage information 

 for determining irrigation practices should be completed in counties 

 around Milner in summer. 1993 and in the Boise and Payette area in 1994.

Flathead River Basin Storage Optimization Study 



The Flathead River Basin Storage Optimization Study is focusing on development 

 of a hydrologic and water quality computer model to evaluate options and 

 capabilities in meeting future water resource demands of the Flathead and 

 related portions of the Clark Fork River basins.
