J2 Regulating Reservoir
Phelps County Canal
J2 Reservoir PurposeRegulate J2 Hydro Releases Beneficially manage reservoir releases for
the project participants
Important Project PointsProject will not create “NEW” waterProject will not affect Supply Canal
diversionsProject will not affect irrigation deliveriesMinor changes to Supply Canal operations
J2 Hydro timingJohnson Lake operations
No planned recreational benefits

ScheduleCompleted work
Many years of study and investigations2+ years of feasibility-level design workOperating agreement signed in July 2013
Moving forward2-3 years of design and permitting2 years of construction starting in 2015-2016
Funding$75 million estimated cost
CNPPID pays 5%, up to $2.5 millionRemainder is split
PRRIP 75% NDNR 25%
Project BenefitsCNPPID
Increased generation efficiencySmooth river fluctuations
PRRIPReduction to target flow shortagesShort Duration High Flow (SDHF) events
NDNROffset for post 1997 groundwater depletions to
stream flows
Address New Activities State and Federal Depletion Plans
Address Existing Activities Reduce deficits to USFWS Target Flows
Flows for testing river management strategies Assists in Short Duration High Flow
(SDHF) J2 Regulating Reservoir works
toward all three
Program’s Water Plan
Addressing New Activities
3 States and Federal Depletions Plans Handles post 1997 depletions
Not counted toward the Program’s water action plan goals – replacing impacts from new activities
Addressing Existing Activities
Reducing Deficits to FWS Target Flows by average annual of 130,000 to 150,000 AFY
Handles depletions existing before 1997
3 Initial Projects:Tamarack I (CO), Pathfinder Modification (WY), andLake McConaughy Environmental Account (NE)
credited 80,000 AFYNew water conservation/supply projects
need 50,000 to 70,000 AFY
USFWS Target Flows and Retiming Excesses
Retime excesses Storage
Acquire by lease or purchase Transfer from agricultural use to environmental use
Water Management Incentives Reduce CU and increase return flows
Water Acquisition
