Proposed 2016 Hydrograph Motion: 

TWG recommends the AMWG recommend to the Secretary of the Interior her 

approval of the DOI-DOE Proposed Hydrograph for Water Year 2016 as follows: 

 Annual Release Volumes will be determined by the 2007 Interim Guidelines 

and shall be reviewed and adopted through the normal annual operating plan 

process (in consultation with the Basin States as appropriate). 

 Monthly Release Volumes are anticipated to shift depending upon: (1) the 

projected Annual Release Volume, (2) powerplant capacity, and (3) the 

magnitude of a potential High Flow Experiment. 

 Monthly Release Volumes may vary within the targets identified below. Any

remaining monthly operational flexibility will be used for existing power 

production operations under the Modified Low Fluctuating Flow (MLFF) 

alternative selected by the 1996 ROD and contained in the 1995 FEIS and in 

compliance with all applicable NEPA compliance documents (HFE EA, NNFC 

EA, 2007 IG). 

 Release objective for June is: 

600 to 650 kaf for annual releases below 9.0 maf 

800 kaf for annual releases of 9.0 maf to less than 9.5 maf 

900 kaf for annual releases of 9.5 maf to less than 10 maf 

Greater than 900 kaf for annual releases 10 maf and greater 

 Release objective for August is: 

800 kaf for annual release below 9.0 maf 

900 kaf for annual releases of 9.0 maf to less than 10 maf 

Greater than 900 kaf for annual releases 10 maf and greater 

 Release objective for September is: 

600 kaf for annual releases below 9.0 maf 

700 kaf for annual releases of 9.0 maf to less than 10.0 maf 

800 kaf or greater for annual releases of 10.0 maf or greater; up to 

powerplant capacity for high equalization releases 

 Monthly Release Volumes will generally strive to maintain 600 kaf levels in 

the shoulder months (spring and fall) and 800 kaf in the December/January 

and July/August timeframe. 

Additionally, the Bureau of Reclamation will continue to apply best professional 

judgment in conducting actual operations and in response to changing conditions 

throughout the water year. Such efforts will continue to be undertaken in 

coordination with the DOI/DOE agencies, and in consultation with the Basin States 

as appropriate, to consider changing conditions and adjust projected operations in a 

manner consistent with the objectives of these parameters as stated above and 

pursuant to the Law of the River.
