Introduction
The purpose of this technical memorandum is to provide water use information for the following fourteen (14) cities, towns, and joint power boards that supply water to their citizens or customers:
Entities that obtain their primary water supply from surface water are:
Entities that obtain their primary water supply from groundwater (and the source aquifer) are:
In this technical memorandum, Appendix 1 provides a summary for each of the fourteen (14) municipal water suppliers. Each summary provides an estimate of the service area population, a brief description of the water supply and the water treatment facilities, the water rates, data pertaining to annual, per capita and peak day water use, and a tabulation of water rights.
Methodology
Primarily, information was obtained from the various municipalities through direct communication or from the municipalities' responses to the WWDC's 1999 Water Supply Survey. If neither of these sources were available, data from the WWDC's "1998 Water System Survey Report" were used.
The impacts to surface water are best represented by depletions, as determined through the following simple relationship: Depletions = Diversions - Return Flow. The estimated surface water depletions were calculated on a monthly basis to accommodate the modeling efforts for the planning study. Therefore, monthly diversion and wastewater discharge information was obtained from the municipalities. Only the wastewater discharge (return flow) that was measured was considered in this analysis. Return flows resulting from irrigation or seepage of the wastewater facilities were not considered as they are highly variable and difficult to realistically estimate. Therefore, the return flows used in this analysis are likely understated, which will result in the depletions being somewhat overstated. However, this methodology is typical for studies relating to municipal water use.
Municipal groundwater use in the Green River Basin has very little, if any, impact on surface water flows due to the depth of the wells. If the municipalities were releasing wastewater discharge to the surrounding streams, those streams would enjoy the benefits or accretions from that discharge. However, representatives from the five (5) communities that use groundwater each represented their wastewater system as having zero or minimal discharge to surrounding streams. Therefore, it was concluded that the groundwater supplies have little or no impacts on the surface water system and groundwater was not considered in the modeling efforts.
Typically, municipalities provide water to customers outside their corporate limits. Therefore, the populations of the service areas are more pertinent than the census information. Further, some of the municipalities or joint powers boards sell water to surrounding water districts. For purposes of this analysis, water sales outside the corporate limits for domestic use is considered municipal water use and is included in the statistics for the various entities. The technical memorandum relating to domestic water use will address this issue further.
In addition, municipalities may sell water to industrial water users. For example, the Kemmerer- Diamondville Joint Powers Board and the Rock Springs/Green River/ Sweetwater County Joint Powers Board sell water to industries outside the corporate limits of their member municipalities. These water sales are not considered municipal water use in this analysis and will be addressed in the technical memorandum addressing industrial water use. Data relating to industrial water sales are readily available, while data relating to domestic water sales is often combined with the total water use for the respective municipalities.
Conclusions
Table 1 on the following page summarizes the water use for the fourteen (14) municipal water suppliers.
Table 2 provides a comparison of reported existing peak day demand with the reported system capacity and the capacity of the direct flow and storage water rights for the thirteen suppliers in the Green River Basin:

Table 2 is offered as an indication that the water suppliers have sufficient system and water right capacity to meet their existing demands, as well as the opportunity to meet the demands of some future growth. However, the suppliers may have other water supply problems in the form of system rehabilitation needs. Further, simply having water rights does not necessarily mean those water rights can meet the demands in drought years. There must be water available at the points of diversion. In addition, the water rights must have priority dates that can withstand water rights regulation in times of shortage.
This analysis is based on current water use. In most cases, water use is based on 1997-1999 data in order to present the current-day situation. However, water users may have a situation that cannot be described with present information. The Rock Springs/Green River/Sweetwater County Joint Powers Board depletes more water, approximately 4,700 acre feet per year, than the other twelve (12) in-basin water suppliers combined, approximately 2,500 acre feet per year. Recently, the Joint Powers Board completed a comprehensive expansion of its water treatment and supply facilities, which removed "bottlenecks" in the previous water supply system. Area water officials believe that water use, particularly in the Rock Springs area, may increase 15% or more as the water supply system can now meet the true demands of the water users.
It is interesting to note that the largest municipal water user in the basin is not located in the Green River Basin. The city of Cheyenne presently diverts an average of approximately 14,400 acre feet of water per year from the Little Snake River Basin to North Platte River Basin, where the water is ultimately exchanged to meet Cheyenne's needs in the South Platte River Basin. The thirteen (13) water suppliers located in the Green River Basin deplete approximately 7,200 acre feet of water per year on an annual basis. Figures 1 and 2 show graphically the apportionment of use by municipality.
Municipal water suppliers are faced with similar problems. They must provide sufficient water of good quality to promote the quality of life their users expect. They must plan for the future to be able to meet the demands of potential future growth. Some of the municipalities are seeking additional growth through economic development efforts.
The water suppliers must comply with state and federal water quality standards, which are being constantly revised and are becoming more stringent. Compliance is becoming more and more costly. Typically, the budgets for water system improvements, operation and maintenance are based on revenues from the sale of water. They must sell water to meet their financial obligations.

Municipality Summary
Entity: City of Cheyenne
Service Area Population: The City of Cheyenne is located in the South Platte River Basin. The city serves a population of approximately 65,000 people. However, the city does not service anyone in the Green River Basin.
Water Supply: A component of the city's water supply system is the Stage I and Stage II Projects. The projects consist of collection and transmission systems in the Little Snake River Drainage. Water is collected on several tributaries of the Little Snake River and delivered to a tunnel which transports the water under the continental divide to Hog Park Reservoir in the North Platte River Basin. Storage in Hog Park Reservoir is released to replace water diverted to Cheyenne through the Rob Roy supply components of the Stage I and II Projects, which transports from the North Platte River Basin to the South Platte River Basin .
Monthly Water Rates: $3.40 base rate plus $2.02 for each 1,000 gallons of usage. Monthly bill for the use of 20,000 gallons = $43.80.
Annual Water Use: Based on the SEO hydrographer reports, the city diverted an average of 14,400 acre feet per year from 1995 to 1997 from the Little Snake Basin. While the reports indicate there has been some seepage into the system throughout the year, the city typically actively diverts water from late April to early July with 97% of the water diverted in May and June. The diversions are typically shut off in early July due to water rights regulation.
Water Supply System Capacity: The estimated potential annual average yield of the Stage I and Stage II Projects is 21,000 acre feet per year. Under drought conditions, this yield drops to 16, 400 acre feet per year.
Municipal Water Rights: The attached tabulation depicts the water rights for the Little Snake Diversion Pipeline, which diverts water from various tributaries to the Little Snake River and delivered to the Hog Park Reservoir through the tunnel under the continental divide. It should be noted that the system serves to divert water during the spring runoff and these water rights are not exercised on an annual or irrigation season basis.
Water Right Capacity: The total permitted capacity of Hog Park Reservoir is 22,656 acre feet, which is the limiting water right under the one-fill limitation.
