until August 24, when all of the water supplies that could be identified for 

 flow augmentation in 1993 became exhausted.

3. 3. A. 2. 8 Shift system flood control space from Dworshak to 

 (page 26) other Columbia Basin projects [Corps of Engineers 

 (Corps) lead], 



Background: In 1991, Reclamation cooperated with the Corps to shift 

 400,000 acre-feet of system flood control responsibility from Dworshak to 

 Grand Coulee. A similar shift was not needed in 1992 or 1993 due to below 

 normal runoff conditions in portions of the Columbia Basin. 



Recent Activity: No further activity Is anticipated for this measure until 

 February 1994 when the initial 1994 runoff forecasts are formulated.

3. 3. A. 3 Reclamation provide 90,000 acre-feet of uncontracted 

 (page 27) water for spring migrants (Reclamation lead). 



Background: In 1991, Reclamation provided about 40,000 acre-feet of 

 uncontracted water as part of 200,000 acre-feet of water that was rented from 

 the Payette and upper Snake River rental pools and used for salmon flow 

 augmentation. In 1992, Reclamation reached agreement with the various 

 Involved entitles to provide 90,000 acre-feet of uncontracted water for summer 

 migrants. Idaho Power Company (Idaho Power) released the water from Brownlee 

 Reservoir in July and Reclamation backfilled Brownlee from Cascade and 

 Oeadwood Reservoirs during winter. 



Recent Activity: Reclamation has arranged to provide 338,000 acre-feet of 

 uncontracted water for lower Snake River flow augmentation in 1993. Sources 

 for this water Include (I) 98,500 acre-feet of uncontracted space from 

 Cascade, Oeadwood, Anderson Ranch, and Ririe Reservoirs, (2) 99,500 acre-feet 

 of presently uncontracted space (but cpinnitted to irrigators as part of the 

 Shoshone-Bannock Water Rights Settlement) from Palisades and Ririe Reservoirs, 

 and (3) 140,000 acre-feet of power head space from Palisades, Minidoka, and 

 Anderson Ranch Reservoirs. Idaho Power released the water from Brownlee 

 Reservoir in June, July, and August, and Reclamation released most of the 

 water from the upstream reservoirs during July and August to backfill Brownlee 

 (except for 120,000 acre-feet which will be released during winter).

3. 3. A. 4 Reclamation provide one-half of 100,000 acre-feet of 



(page 27) water for spring migrants from Snake River basin when 



forecasted runoff at Lower Granite is less than 

 29 million acre-feet (MAF) (Reclamation co-lead). 



Background: The main activity associated with this measure during 1991 and 

 1992 was to monitor the Idaho rental pools to determine if any water was 

 available to be purchased for lower Snake River flow augmentation. In 1991,
