A brief description of each follows:
| Big Sandy Reservoir | Big Sandy Reservoir Outlet |
 |
|
| A Bureau of Reclamation project, the Big Sandy Reservoir is formed by an earthen dam located on the Big Sandy River about 10 miles north of Farson, Wyoming. The storage capacity of 39,700 AF is permitted for irrigation use, but the reservoir also provides local recreational benefits. The reservoir is operated by the Eden Valley Irrigation and Drainage District. Additional information and data are available at http://dataweb.usbr.gov/html/eden.html on the internet [new link 10/2009 HERE]. |
Black Joe Lake
Black Joe Lake, located high in the Wind River Range in the upper reaches of the Big Sandy River, is a natural lake with its storage increased using a small dam. The dam is constructed of rock-filled timber cribbing and is approximately 13.5 feet in height. This embankment increases storage in the reservoir by 1,101.8 AF, which is permitted for irrigation. Nearby is Clear Lake, a sister lake with a similar dam, also enlarged, with a permitted capacity of 318.6 AF.
Boulder Lake
Boulder Lake, as currently configured, is a natural lake which has been raised by the addition of a dam at the outlet. With an enlargement, the reservoir now impounds over 22,000 AF above the natural lake level. The additional storage is permitted for irrigation use. Boulder Lake is a morainal lake located on the western flank of the Wind River Mountains and is, in this regard, similar to Fremont, New Fork and Willow Lakes. Boulder Lake has no staff gage or lake level instrumentation, so storage fluctuations can only be estimated. Boulder Lake irrigation releases are managed by the Boulder Irrigation District.
Bush Lake
See Hay Reservoir.
Bush Creek Reservoir
Bush Creek Reservoir is constructed to be fed by a canal from Bush Creek, located in the Great Divide Basin. On maps it is sometimes denoted John Hay Reservoir. The outlet is not tributary to the Green River. This reservoir has a permitted capacity of 17,266.651 AF designated for irrigation, stock, and domestic uses.
Divide Lake
Divide Lake is located in the Wind River Range on Divide Creek, tributary to Boulder Creek (upstream of Boulder Lake) and the New Fork River. It is an enlargement of a natural lake, with a dam constructed of a combination earthfill/rock filled cribbing structure. The dam stores a permitted capacity of 1,027.36 AF designated for irrigation, stock, and domestic uses in the Scab Creek drainage.
Eden Reservoir
Originally permitted as "Eden Irrigation and Land Company No. 1," the Eden Reservoir is an off- channel reservoir fed from the Little Sandy River and from Big Sandy Dam. Impoundment is created by three irregular dikes. Its total storage capacity, as permitted, is almost 18,500 AF, although current operations limit storage to 12,190 AF for stability reasons. Along with Big Sandy, Eden serves the Eden Valley Irrigation District. Originally planned for removal by the Bureau of Reclamation, Eden Reservoir still exists to provide irrigation water. Additional information and data are available at http://dataweb.usbr.gov/html/eden.html on the internet. [new link 10/2009 HERE]
Elkhorn
Alternately named Little Sandy Reservoir, Elkhorn Reservoir is located high on Little Sandy Creek in the southern Wind River Range. It is an enlargement of a natural lake, containing 1,450 AF permitted for stock and irrigation uses.
Flaming Gorge
Created by a concrete arch dam in Utah, Flaming Gorge is a Bureau of Reclamation Project on the main stem of the Green River. The reservoir has no Wyoming water right, and serves no lands in Wyoming, although a significant amount of its surface area is in Wyoming. The capacity of Flaming Gorge is 3,789,000 AF, which is used for irrigation, power, fish and wildlife, and recreation. More information can be found at http://dataweb.usbr.gov/dams/ut10121.htm on the internet [new link 10/2009 HERE]. Because it contains no Wyoming water rights, Flaming Gorge Reservoir is not described in the Reservoir Summary Sheets.
| Fontenelle | Fontenelle Dam |
 |
|
| Another Bureau of Reclamation project, Fontenelle Reservoir is an earthen dam on the main stem of the Green River, located just downstream of the town of LaBarge. With a storage capacity of 345,397 AF, Fontenelle is a multi-purpose project with permitted uses that include irrigation, domestic, industrial, municipal, stock, fisheries, recreation, and hydropower. Additional information and data are available at http://dataweb.usbr.gov/html/seedskadee.html on the internet. [new link 10/2009 HERE] |
Fremont Lake
A morainal lake, Fremont is the seventh deepest lake in the contiguous United States, excluding the Great Lakes. Like Boulder, Willow, and New Fork Lakes, its level has been raised over time by the addition of a dam at the outlet. Having been enlarged several times, Fremont Lake now impounds over 30,000 AF above the natural lake level, of which about 25,400 AF is usable (available to the newest outlet). Fremont Lake has outstanding clarity. It serves not only irrigation and recreation uses, but is also the municipal supply for the Town of Pinedale, Wyoming. Other uses listed on permits for Fremont Lake include hydropower, industrial, and fisheries. The "Fremont Lake Reservoir Operating Guide" (Gilbert, 1996) provides detailed information on the lake, its watershed characteristics, and general operating recommendations.
Hay Reservoir
The Hay Irrigation Project includes both Hay and Bush Lake Reservoirs. These reservoirs are situated about 30 miles north of I-80 nearly midway between Rawlins and Rock Springs, and are about 10 miles southeast of Bush Creek (John Hay) Reservoir. Hay Reservoir, which has been enlarged, is permitted to store approximately 5,840 AF for irrigation and stock uses. The Bush Lake Reservoir stores approximately 1,390 AF.
High Savery Reservoir
Yet to be constructed, High Savery Reservoir will provide supplemental irrigation water to the Savery Creek and Little Snake River valleys in the southeastern corner of Wyoming's Green River Basin. Located high on Savery Creek in Carbon County, High Savery will impound over 22,400 AF to provide an annual 12,000 AF yield of supplemental late-season irrigation water. As planned, High Savery will be impounded by an earthen dam. The reservoir will be owned and permitted by the State of Wyoming, and operated by the Savery - Little Snake Water Conservancy District.
Kemmerer City (Kemmerer No. 1) Reservoir
Located on the Hams Fork near the Town of Kemmerer, Wyoming, this reservoir serves as a diversion point for the town's municipal water supply. With 1,058 AF of storage, it is not large in comparison with other reservoirs in the basin.
McNinch No. 1 & 2 Reservoirs
The McNinch reservoirs are private impoundments located on McNinch Wash, tributary to North Piney Creek. They are situated about one mile west of Sixty Seven Reservoir. McNinch No. 1 is fed by Beaver Creek and Spring Creek, both tributary to North Piney Creek. McNinch No. 2 is fed by McNinch Wash (McNinch Draw). Capacities are 1,086 AF for No. 1, and 198 AF for No. 2. Both reservoirs are permitted for irrigation, stock, and domestic uses.
| Meeks Cabin Reservoir | Meeks Cabin Dam |
 |
|
| Meeks Cabin Dam is a Bureau of Reclamation Project on the Blacks Fork (of the Green) River. Located near the Utah border, Meeks Cabin provides water for irrigation and stock from its 33,571 AF permitted capacity. The reservoir is operated by the Bridger Valley Water Conservancy District. Additional information and data are available at http://dataweb.usbr.gov/html/lyman.html on the internet. [new link 10/2009 HERE] |
Middle Piney Lake
Middle Piney Lake is located on the headwaters of Middle Piney Creek in the Bridger National Forest. It is situated about 15 miles due west of the McNinch reservoirs. The reservoir contains 4,201 AF of storage permitted for irrigation, stock ,and domestic uses. In 1997, the interest in the reservoir was assigned to the USDA Forest Service. Currently, the reservoir is operated with the outlet gates fully open, essentially passing water through the reservoir.
New Fork Lake
Among those listed here, New Fork Lake is the northernmost of the morainal lakes on the east flank of the upper Green River Basin. It is located on the upper New Fork River, a major tributary of the Green River. As with Fremont, Boulder, and Willow Lakes, its capacity has been increased by man. Currently, the lake stores 20,340 AF over and above the natural lake level. Water in this storage is permitted for irrigation use. Releases for use by the New Fork Irrigation District do not enter any single large canal near the dam. Instead, the river itself is the major conveyance, with individual irrigators taking storage water from the river at their own headgates.
Pacific Reservoirs No. 1 and 2
These two reservoirs are located on the very upper reaches of the Pacific Creek Basin, which is tributary to Little Sandy Creek, in Fremont County. Permitted capacities for the two reservoirs are 106.91 AF for No. 1 and 1,394.21 for No. 2. Interestingly, both reservoirs store water from the Sweetwater River via transbasin diversion. Both reservoirs are permitted for irrigation and stock uses.
Paterson Lake
Located about 1 mile northwest of Lyman, Paterson Reservoir is also denoted as Rollins Reservoir on some maps. It is an off-channel reservoir fed by the Fort Bridger Canal from the Blacks Fork River. The reservoir contains 1,237 AF permitted for irrigation use.
Silver Lake
Silver Lake is located in the Wind River Range on Silver Creek, tributary to the East Fork New Fork River and the New Fork River. Permitted for irrigation and stock use, the maximum capacity of the reservoir, as enlarged, is 2,151.63 AF.
Sixty-Seven
This reservoir is an off-channel structure fed by the Hughes Ditch from North Piney Creek and from Spring Creek, a tributary of North Piney Creek. As enlarged, the reservoir stores 4,329 AF for irrigation, stock, and domestic purposes. The reservoir is located about 6 miles northwest of the Town of Big Piney.
Stateline Reservoir
Stateline reservoir is located entirely within the State of Utah, and has no State of Wyoming permits. However, water within its storage capacity is used for irrigation of Wyoming lands and for municipal use in the Lyman/Fort Bridger valley. Additional information and data are available at http://dataweb.usbr.gov/html/lyman.html on the internet. [new link 10/2009 HERE]
| Viva Naughton | Viva Naughton Reservoir |
 |
|
| Viva Naughton Reservoir is operated by the Naughton Power Plant in Kemmerer. This plant (previously owned by PacifiCorp, now owned by Scottish Power) uses water from the reservoir for cooling needs of the coal-fired process. While no irrigation uses are explicitly listed in the permit, Naughton does release water for downstream irrigation during times of sufficient supply. Similarly, while Viva Naughton is not a flood control structure, the owner does try to operate the plant in a fashion to minimize downstream flooding. Constructed capacity of the reservoir is 45,465 AF. |
Willow Lake
Willow Lake is the last morainal lake on this list. This lake is located on Lake Creek, tributary to the New Fork River. Operation is not by any particular district or political entity, but by owners of "shares" in the lake's storage. Located north of Fremont Lake, the man-made storage is permitted for irrigation, stock, and domestic uses. The total permitted amount of the additional storage is 18,816 AF.
Evaporation
Evaporation from reservoirs constructed by man is a consumptive use associated with the beneficial use of water for other purposes and is charged against Wyoming's allocation under the Upper Colorado River Basin Compact. Traditionally, evaporation estimates are calculated by the Bureau of Reclamation and published in the "Consumptive Uses and Losses Report," (CULR) which is prepared every five years. In this report, the larger Bureau reservoirs in the Green and Colorado River Basins are classified as "main stem" reservoirs, the evaporation from which is tabulated and carried separately from evaporation calculated for in-state reservoirs. Upper Colorado River Basin main stem reservoirs include Flaming Gorge, Blue Mesa, Morrow Point and Lake Powell.
For these main stem reservoirs, the aggregate evaporation is charged against the various states' apportionment in the percentage allowed for each state by the Upper Colorado River Basin Compact, under full development (full use of allowed depletions). By this Compact Wyoming is allowed 14 percent of the total depletions allowed the States of the Upper Division (the Upper Basin States minus Arizona) by the Colorado River Compact; therefore, at full development, 14 percent of the Upper Basin mainstem evaporation is charged to Wyoming. Prior to full development, Article V of the Upper Colorado River Basin Compact states that Wyoming's share will be calculated as the same fraction of main stem evaporation as Wyoming's consumptive use bears to the total consumptive use by States of the Upper Division.
For the years 1986-1990, Wyoming's fraction of the total consumptive use of the Upper Division states was 13.55 percent. In these same years, the average main stem evaporation was 653,000 acre-feet. Therefore, Wyoming's charge for main stem evaporation would be calculated as 88,482 acre-feet. This value, however, overstates the amount of Wyoming's main stem evaporation portion when the basin sees full development. Under full development of all states' full compact allotments, reservoir levels will average lower than they do now, due to increased drawdowns. Under this scenario the Bureau estimates a full development main stem evaporation of 520,000 acre-feet annually, from which Wyoming's 14 percent charge can be estimated to be 72,800 acre-feet annually (Bureau of Reclamation, January 1999).
Reservoirs not included in the main stem calculations are handled separately and the evaporation therefrom is charged totally to the state within which they reside. In Wyoming, the Bureau has identified 76 individual reservoirs in the Green River Basin for which evaporation is explicitly calculated. Table 1 lists these reservoirs and the net annual evaporation at each for the years 1986-1990, which is the last full five year period for which a final CULR is available. The Bureau charges evaporation without regard to the uses for which a reservoir is permitted. That is, no separate accounting is kept for evaporation from irrigation, recreation, fish and wildlife or other pools.
In Table 1, Bureau evaporation values have been altered for New Fork, Boulder, Willow and Fremont Lakes. In the CULR supporting documentation for these lakes, all of which originally were natural lakes raised by dams added at their outlets, the evaporation calculated uses the full high water line areas in the calculation. Because only that depletion caused by the actions of man should be counted against the Compact allocation, these estimates have been revised to reflect only the incremental evaporation loss due to the incremental surface area increase caused by raising the lakes. To do this, evaporation was calculated for the increase in high water line surface area, not for the lake as a whole. These changes result in a net savings in evaporation of approximately 4,082 acre-feet, as described below:
| Reservoir | Natural HWL Surface Area, ac | Enlarged HWL Surface Area, ac | Difference, ac | Net Evaporation, from CULR, in. | Actual Evaporation due to Man, AF | CULR Evap, as reported, AF | Difference, AF (savings) |
|---|---|---|---|---|---|---|---|
| Boulder | 1540 | 1676 | 136 | 22.3 | 253 | 1872 | 1619 |
| Fremont | 4888 | 5122 | 234 | 20 | 390 | 0 | -390 |
| New Fork | 1296 | 1416 | 120 | 19 | 190 | 1345 | 1155 |
| Willow | 1800 | 1958 | 158 | 20 | 263 | 1961 | 1698 |
| Total |
| 1096 | 5178 | 4082 |
Two sources of data exist for estimating evaporative losses from reservoirs in Wyoming. These include the National Weather Service (Farnsworth et al, June 1982) and Lewis (1978). Because it is newer, of national scope, and used by the Bureau of Reclamation in its Consumptive Uses and Losses Report calculations, the NWS document is used for annual gross (free water surface) evaporation values herein. However, the NWS document does not give a monthly distribution of evaporation rates. For this, the distribution pattern for Pathfinder Dam (Lewis, 1978) is used.
The net evaporation rate at a reservoir, or the true amount lost after correction for rainfall, is calculated as gross evaporation minus average precipitation by month. Data describing gross evaporation and precipitation on an average monthly basis are provided as part of Appendix A. The source of precipitation data for use in estimating net evaporation is Daly and Taylor (1998).

Operating Notes: Eden Valley Irrigation and Drainage District operates the Big Sandy
Reservoir. The reservoir is operated to provide water to the district members on a
call basis, through a canal system. The canals include the Means and Eden Canals, the
Eden and West Side Laterals, and the Farson Lateral. Recent construction of regulating
reservoirs for pump stations has decreased delivery delays to farmers, which used to
be significant, and helped with application efficiency. EOM data developed from USBR

Operating Notes: Irrigation releases are typically in the range of 360 cfs from May
15 to July 15. Releases occur at the dam and are picked up at the Boulder Irrigation
Canal approximately 2 miles below the dam. Fall operations include a diversion of 100
to 125 cfs in September to increase soil moisture before winter. Approximately 35 cfs
is diverted in October for stock water. The Howard-Ruth ditch is directly below the
dam and annually purchases storage water from the lake.
Boulder Reservoir has no staff gage, and no storage records are kept.

Operating Notes: Fontenelle is generally operated to maximize storage, power
generation and flood mitigation. It also is used to maintain the aquatic and riparian
habitat at Seedskadee Wildlife Refuge. Releases are typically 1,200 to 1,400 cfs from
August to April. During spring runoff, releases are increased to maintain reservoir
pool elevation increases to 1 to 2 feet daily. The maximum elevation target is 6,506
feet, or 345,000 AF in storage. The operator (Bureau) endeavors to keep release peaks
below inflow peaks, which average about 11,000 cfs. After spring runoff ceases and
peak storage is met, releases are again set back to 1,200 to 1,400 cfs.

Operating Notes: Highland Irrigation District is the operator of the dam. Operating
procedures are as follows: Beginning Nov. 1 each year, inflow bypasses are adjusted
in an effort to satisfy storage rights while maintaining a reasonable fishery in
Pine Creek below the dam. During spring runoff, inlows will be used to meet storage
rights as well as downstream irrigation rights. Otherwise, endeavor to operate the
reservoir such that all rights, even those not signatory to the operating procedures,
are not adversely affected in times of water shortage. Discharges from the reservoir
can be taken directly into the Highland and Fremont Irrigation Canals or returned to
Pine Creek.

Operating Notes: This reservoir serves the City of Kemmerer. The reservoir itself
used to be the point of diversion for the city treatment plant; however operational
changes are such that the city now diverts from the Hams Fork River downstream of the
reservoir. There are no special operating criteria for this reservoir, it is
typically operated as a flow-through structure with little, if any, changes made to
the gate settings.

Operating Notes: Meeks Cabin Reservoir is operated by the Bridger Valley Water
Conservancy District on a call basis. District members are provided water upon
demand, usually after their requirements cannot be met from direct flow water rights
due to recession of runoff. Typically, about 30 percent of the annual reservoir
demand is used prior to the hay cutting (July 24, in a typical year), with the
remainder used in the fall to fill the soil profile. Meeks Cabin Reservoir has a 10
cfs minimum by-pass amount.

Operating Notes: New Fork Lake is owned and operated by the New Fork Lake Irrigation
District. It is operated primarily as an irrigation storge reservoir. Runoff is
stored in the reservoir until elevation 38.0 is exceeded, at which point water will
begin to flow through the spillway. Release of water through the outlet is dependent
on manual operation of three (3) slide gates, and is governed by irrigation needs and
adjudicated water rights. There is no major District canal or ditch which is fed by
the reservoir; the New Fork River itself is the primary conveyance with individual
irrigators diverting directly therefrom.

Operating Notes: State Line Reservoir is operated by the Bridger Valley Water
Conservancy District on a call basis. District members are provided water upon
demand, usually after their requirements cannot be met from direct flow water rights
due to recession of runoff. Typically, about 30 percent of the annual reservoir
demand is used prior to the hay cutting (July 24, in a typical year), with the
remainder used in the fall to fill the soil profile. In addition, municipal supplies
are provided from June through September each year by agreement between the District
and the Lyman-Fort Bridger Joint Powers Board. The State Line Reservoir has a 7-cfs
minimum by-pass amount.

Operating Notes: Viva Naughton is operated to provide a continous supply of 25 cfs
for cooling water to the Naughton Power Plant. The reservoir is sized to provide this
amount under a 2-year drought scenario. Irrigation is not explicitly permitted in the
reservoir's water right, but prior rights are bypassed and water for irrigation is
released from storage for downstream irrigators if water supplies are sufficient.
Flood control is also not explicitly stated in the permit, but the reservoir can and
has been operated to reduce flooding effects downstream.

Operating Notes: Willow Lake is operated primarily for irrigation. the lake
ownership, unique to the area, is divided into "shares", the majority of which are
owned by the Binning family. The operational and maintenance history of the reservoir
is incomplete. The 2nd enlargement is unadjudicated with some information that the
first two permits are not fully built.
Unless otherwise noted, all contours, areas, capacities and notes were taken directly from permit maps.
