8.4.6 Supplemental Studies
Reservoir studies have been commissioned by the WWDC to supplement the information
contained in the Basin Plan. These studies are summarized below.
Green River Ground Water Recharge and Alternative Storage, Level I Project
This study, performed by States West Water Resources Corporation (SWWRC, 2001)
investigated the potential for groundwater recharge and potential storage sites in the Green River Basin.
The study evaluated needs within the basin, which have been summarized earlier in this report. Screening
of the short list projects resulted in seven storage projects being investigated in detail. These sites
included the following projects, which are shown on Figure 8-2.
! Sand Hill Reservoir
! McNinch Reservoir
! East Fork River Reservoir
! East Fork Gorge Reservoir
! Church Reservoir
! Viva Naughton Enlargement
! Dempsey Basin Reservoir
Agricultural shortages within the Green River Basin are confined to the tributaries. The SWWRC
(SWWRC, 2001) report identified projects to address shortages in the East Fork of the New Fork, Hams
Fork, and the Piney Creek tributaries. The results of the secondary screening process indicate that
agriculture probably cannot afford the projects as single-purpose reservoirs. The potential for developing
these projects for multiple use should be considered. The Hams Fork projects, including the Viva
Naughton Enlargement and Dempsey Basin off-channel storage project, are currently being studied as
multipurpose projects.
Middle Piney Reservoir Rehabilitation-Level II Study
This study was commissioned by the WWDC in 2006. The objective of the study is to determine
the rehabilitation improvements necessary to utilize approximately 4,200 acre-feet of existing storage.
Dam safety issues presently preclude use of the storage.
Upper Green River Storage Study
This study was conducted by Kleinfelder, Inc. in 2007 to evaluate shortages and potential need in
the Upper Green River Basin. The study evaluated the following potential reservoirs as shown on Figures
8-2 and 8-3.
! Lower Willow Creek Reservoir (Little Snake River Basin)
! Mickelson Creek Reservoir
! Horse Pasture Draw Reservoir
! Cow Gulch Reservoir
