The Flathead River Basin Storage Optimization Study is addressing the multiple 

 water demands and water uses of the Flathead River basin and related portions 

 of the Clark Fork drainage in western Montana. A linked hydrologic and water 



auality computer model for the Clark Fork/Flathead River basin is also being 

 eveloped. The model will be used to evaluate options and capabilities for 

 meeting future demands for instream flows, supplemental irrigation, power, 

 fish and wildlife, and recreation. 



Current Status 



A work station with linked water quality and hydrologic models is 

 planned to be installed in late summer. 1993.

Josephine County Water Management Improvement Study 



Background 



The Grants Pass Irrigation District (GRID), part of the Rogue River Basin 

 Project, serves approximately 7800 acres with natural flows diverted at Savage 

 Rapids Dam. 



In 1971. Congress passed Public Law 92-199 directing the Secretary of Interior 

 to perform a feasibility study of the Grants Pass Division of the Rogue River 

 Basin Project. A major facet of this study was evaluation of anadromous fish 

 passage problems at Savage Rapids Dam. Public Law 93-493. passed in 1974. 

 authorized construction of interim modifications to the fish passage 

 facilities. This work was completed, but identification and implementation of 

 measures to fully correct the problems were delayed for a variety of reasons. 

 A major element of the current study (initiated in October 1988) is to assist 

 the GPID and others to identify implementable solutions to the fish passage 

 problems and seek funding for appropriate implementation. 



In addition to the fish passage issue, the State of Oregon's Water Resources 

 Department completed a final proof survey of the Grants Pass Irrigation 

 District's service area in the early 1980's. As a result, the district 

 received a water rights certificate which provides for diversion of 

 approximately 97 cfs based on a water duty of 1 cfs per 80 acres. This is a 

 little over half of the district's historical diversion rate of 180 cfs. The 

 District was issued a temporary permit to continue diversions at the historic 

 rate while developing a plan to reduce these diversions. This permit calls 

 for submittal of a water management plan to the Oregon Water Resources 

 Commission in March 1994. 



The conservation element of the study is focused on working with Federal. 

 State, and local agencies and entities to address (among other things): 



• The role of an irrigation district in an urbanizing area 



• I nral watpr rpniiirpmpntt;
