Two other types of information are mentioned in the lWMC' s Scope of Services under Water Action
Plan requirements, which include: I) monitoring and accounting methods; and 2) recommendations
concerning how Program water moves through the system to maximize benefits to the habitat.
These two topics are addressed in Chapters IV and V, respectively,

1. CNPPID RE-REGULA rING RESERVOIR

o Location:

Several re-regulating reservoir options were evaluated by HDR Engineering Inc. (HDR)
for Central Nebraska Public Power and Irrigation District (CNPPID), The HDR report, .
titled Depletion Mitigation Study Phase 1, was recently finalized and made available to
Boyle Engineering on April 13, 2000, Tne HDR report has been relied on for
information on potentia! re-regulating reservoirs within CNPPID's system.

Nebraska indicated they are willing to consider are-regulating reservoir(s) capable of
yielding an annual average of up to 8,000 ac-ft of target flow reductions at the critical
habitat, of which 50 percent would be made available to the Program, The remaining 50
percent of the yield will be retained by N~braska to potentially offset future depletions.
An average of up to 8,000 ac-ftlyr of target flow reductions could be attained through a
single re-regulating reservoir or a combiI}ation of reservoirs. As such, the six most
promising re-regulating reservoir options evaluated in the HDR report are presented
below.

The site locations of the six re-regulating reservoirs listed in order by location from west
to east are described as follows:

Option 1: Jeffrey Canyon Reservoir. 1;his site is located south of Brady in Lincoln
County on the south side of CNPPID's 'Tri-County Cana! (Canal). This reservoir would
be fed from Jeffrey Reservoir. The reservoir capacity is estimated to be 10,390 ac-ft.

Option 2: Smith Canyon Reservoir. This site is located southwest of Gothenburg in
Dawson County on the south side of the Canal. This reservoir would be fed by water
pumped from the Canal. The reservoir capacity is estimated to be 12,895 ac-ft.

Options 3&4: Midway Lakes Reservoirs No.2 and No.5. These sites are located south
of Willow Island in Dawson County on the south side of the Canal. These reservoirs
would be fed by water pumped from the 'Canal. The capacities of Midway Lakes
Reservoirs No.2 and No,S are estimated to be 6,433 ac-ft and 11,429 ac-ft, respectively,

Option 5: North Plum Creek Reservoir. This site is located southeast of Cozad in
Dawson County on the north side of the pana!. This reservoir would be fed by water
from the Canal. The reservoir capacity i~ estimated to be 2,320 ac-ft.
