2 J2 REGULATING RESERVOIR CONCEPT CNPPID Diversion Platte River J2 Return J2 J2 Regulating Reservoir Phelps County Canal

3 J2 Reservoir Purpose Regulate J2 Hydro Releases Beneficially manage reservoir releases for the project participants

4 Important Project Points Project will not create NEW water Project will not affect Supply Canal diversions Project will not affect irrigation deliveries Minor changes to Supply Canal operations J2 Hydro timing Johnson Lake operations No planned recreational benefits

5 Participants Platte River Recovery Implementation Program Nebraska Department of Natural Resources Twin Platte NRD Tri-Basin NRD Central Platte NRD Central Nebraska Public Power and Irrigation District

6 Location Northwest Phelps County Downstream of J2 Hydropower Plant Between the Phelps Canal and Platte River

7

8 BERTRAND HWY RIVER ROAD

9 Preliminary Design 2 cells 1,000 land acres 15,000 acre feet capacity Clay liner and drains Soil cement slope protection Inlets on Phelps Canal Outlets to Platte River

10

11 Operations CNPPID will be owner/operator Route water to reservoirs through Phelps Canal Regulate J2 Hydro releases Retime excess flows River fluctuations Irrigation demand

12

13 Schedule Completed work Many years of study and investigations 2+ years of feasibility-level design work Operating agreement signed in July 2013 Moving forward 2-3 years of design and permitting 2 years of construction starting in 2015-2016

14 Funding $75 million estimated cost CNPPID pays 5%, up to $2.5 million Remainder is split PRRIP 75% NDNR 25%

15 Project Benefits CNPPID Increased generation efficiency Smooth river fluctuations PRRIP Reduction to target flow shortages Short Duration High Flow (SDHF) events NDNR Offset for post 1997 groundwater depletions to stream flows

16 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 Programs Water Plan

17 Addressing New Activities 3 States and Federal Depletions Plans Handles post 1997 depletions Not counted toward the Programs water action plan goals – replacing impacts from new activities

18 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), and Lake McConaughy Environmental Account (NE) credited 80,000 AFY New water conservation/supply projects need 50,000 to 70,000 AFY

19 USFWS Target Flows and Retiming Excesses

20 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
