Agricultural water use represents the vast majority of water use within the Wind/Bighorn River Basin planning area. Because of this, accurate estimation of agricultural water use within the basin is essential in producing an accurate model and calculating water availability. Water use by agriculture is a function of many physical and managerial functions including the quantity of land irrigated, crop types, conveyance mechanisms, irrigation types and management styles.
The model requires the historical diversion requirement for each point of diversion. Then, the model calculates the historical amount of consumptive use using irrigation efficiencies and returns non-consumptive demands back to the river according to surface water accretion functions, or lags. Then, because the amount of land historically irrigated is less than the amount of land with water rights, full supply diversions are modeled, where all irrigated lands with water rights are supplied from the existing water supplies. The development of historical diversions (both measured and estimated) as well as fully supply diversions are discussed in the following sections.
Section 2 - Historical Diversions
Historical diversions are used as input for the model calculation and calibration process. Therefore, based upon criteria used in previous river basin plans, historical diversion records were obtained for all diversions greater than 10 cfs. Diversions greater than 10 cfs are explicitly included in the model as separate diversions, while those less than 10 cfs are .lumped. with other small diversions less than 10 cfs that divert in the same reach of stream. Diversion records and the reduction of the diversion records for use in the model is discussed in this section. Estimated historical diversions for those diversions without diversion records are discussed in Section 3 . Estimated Historical Diversions.
Diversion records were collected from the State Engineer.s Office Division 3 Hydrographer.s Reports and USGS gaged flow, as detailed in the Technical Memorandum Wind/Bighorn River Basin Plan Irrigation Diversion Operation and Description (BRS, 2003b). Two types of records are available:
The reduction of daily data simply used the daily average diversion flow rate and converted it to a volumetric amount. Any missing daily data was estimated from the available data before and after the missing data using linear interpolation. Then, the daily volumetric amounts were summed for a monthly diversion. For most data in the Hydrographer.s reports, this is already done and these values were used.
The reduction of spot data involved a similar process. Data for days not measured was linearly interpolated from the available data. Starting and ending dates for irrigation seasons were taken from Consumptive Use and Consumptive Irrigation Requirements in Wyoming (Pochop, 1992). The daily flow values were then converted to monthly volumes and summed for each month.
Monthly diversions estimated from the daily and spot data were used to develop dry, average and wet year diversions. The development of dry, average and wet years, as well as the index gages for each basin are described in Technical Memorandum 2A/2B Surface Water Hydrology(MWH, 2002). In general, the 1973-2001 period-of-record was used for hydrologic calculations. Based upon selected index streamflow gages, which generally represent undepleted flows, dry years were defined as the driest 20 percent of years, average years were the middle 60 percent, and wet years were wettest 20 percent of years, as defined by the total annual flow at the gage.
To reduce diversion data, the monthly average of all available diversion data was taken for all years within the hydrologic condition. Unlike the gaged flow records, years without data were not filled. Therefore, occasionally, there are diversions with records in one hydrologic condition and not another. In this case, the estimated actual diversion methodology was used for the missing data. This primarily occurred only for smaller diversions.
Occasionally, calibration of the model required that the measured historical diversions be reduced to maintain mass balance in the model. This was accomplished using the same techniques as described in Section 4 . Full Supply Diversion Requirements.
A summary of the measured data as used in the model for each basin is presented in Table 2-1, Table 2-2 and Table 2-3, while the monthly measured diversion data is shown in Appendix A. There are very few diversions with long periods-of-record within the Wind River Basin, especially on the Wind River Reservation. It should be noted when reviewing the historical diversion data that some of the measurement points presented are at locations within a delivery system and do not necessarily represent additional diversions from the river. For instance, a large portion of the Dry Creek Canal diversion comes from the Dinwoody (feeder) Canal. Therefore, the values presented in the tables cannot simply be summed to find the diversion for the entire basin. Those canals that act as feeder canals for other diversions must be noted and the appropriate volume of water taken out of the receiving canal. This can be difficult for those feeder canals that also deliver water to irrigated lands along their routes and thus, this has not been done for presentation purposes. However, these are taken into account in the modeling through the actual structure of the model by setting return flow values and locations so that the appropriate amount of water is delivered to the receiving canal.

Notes:
- No data available for the hydrologic year. Diversion estimated using techniques described in Section 4 -
Full Supply Diversion Requirements.
Section 3 - Estimated Historical Diversions
Because diversion records were not available for many of the smaller diversions within the study area, and because some diversion records were not obtained (those that did not meet the 10 cfs criteria), estimated historical diversions were developed. The quantification of estimated historical diversions for those irrigated lands without historical diversion records took place in two parts:
The development of estimated historical diversion requirements for input into the model was performed in the same manner as described in Section 4 - Full Supply Diversion Requirements.
The calibration procedure, as more fully described in Task 3B/3C Technical Memorandum, Spreadsheet Model Development and Calibration (MWH, 2003), was used to adjust the estimated historical diversions. This calibration procedure utilizes the estimate of water availability at the point of diversion and compares it with the estimated historical diversion. If the estimated historical diversion is less than the amount of water available at the point of diversion, then the estimated historical diversion is not adjusted. If the estimated historical diversion is more than the available flow at the point of diversion, then the estimated historical diversion is adjusted so that it can take no more than the available streamflow. These adjustments are shown on the .Historical Diversions. worksheet within each model. See the Task 3B/3C Technical Memorandum, Spreadsheet Model Development and Calibration (MWH, 2003) for further information on the model and calibration process.
Section 4 - Full Supply Diversion Requirements
Full supply diversion requirements are based on the theoretical consumptive use and system efficiencies for each of the points of diversion. In general, the full supply diversion requirement is equated to the theoretical maximum diversion requirement as given in the following equation.
Each of these factors is described in the following sections.
4.1 Irrigated Lands
Mapping of irrigated lands within the basin was performed by the project team. Irrigated lands mapping is discussed more thoroughly in the Task 2A Technical Memorandum Wind/Bighorn Lands Mapping and Water Rights Data (TriHydro, 2003). This mapping was used for determining the area of land irrigated in each sub-basin model.
The irrigated lands mapping was attributed in the GIS as Irrigated Land (IRR), lands with Water Rights (Water Rights), man-made riparian (MM RIP) and sub-irrigated (SUB IRR) (Tri-Hydro, 2003). Islands of non-irrigated lands within larger irrigated areas, or polygons within polygons in the GIS database, were also mapped.
A summary of the irrigated lands is shown in Table 4-1. As shown in Table 4-4 (Section 4.3 of this report), the USDA estimates approximately 344,000 acres of irrigated lands while the Wyoming Agricultural services estimates approximately 354,000 acres of irrigated lands within the study area. Table 4-1 shows approximately 561,000 acres of irrigated lands with an additional 125,000 acres of lands with water awards. There are many reasons for the differences in estimates, including the non-reporting of irrigated lands by many farmers, and the fact that some of the lands could have been fallow during the reporting year.

4.2 Theoretical Crop Irrigation Requirement
Crop consumptive use requirement is the maximum water use of a well-watered crop under optimum growing conditions (Pochop; et al, 1992). A portion of the crop consumptive use is met by effective rainfall (or rainfall that reaches the root zone and meets a portion of the consumptive water requirement before occurring as surface runoff). The portion of the crop consumptive use that is not met by rainfall is referred to as the Crop Irrigation Requirement (CIR). Actual conditions often vary from the theoretical CIR for a variety of reasons, such as the micro-climates at the site that may be different from the climate station, variations in genetics of different strains of the same crop, and more likely, varying soil types. However, CIR gives an estimate of the amount of water that is required to produce a crop under ideal conditions on a system-wide basis.
As has become a standard for use in the WWDC river basin plans, the crop irrigation requirements presented in Consumptive Use and Consumptive Irrigation Requirements . Wyoming (Pochop, et al, 1992) were used in this analysis. The study utilizes 1951 . 1990 climatic data to calculate CIR for several crops and climate stations throughout the study area. Because climatic dry, average and wet periods in summer months during irrigation are often different than the dry, average and wet periods in the winter that produce runoff, the average CIR was used for all three hydrologic conditions.
There are 13 climatic stations within the Wind/Bighorn River Basin at which CIR is reported. CIR continually varies between these stations based on localized climate, topography, elevation, etc. However, normally, these variations are small and for regional planning efforts, the CIR values can be extended to areas outside of the exact climatic station location. For purposes of this analysis, the Theissen polygon method was utilized to determine the .influence area. for each climatic station. This method draws lines between each station, then bisects them midway with a perpendicular line. The intersections of these bisection lines makes up polygons for which all irrigated lands within the polygon uses the CIR at the climatic station. The climatic stations and their associated acreages within each basin are presented in Table 4-3, while a map showing the climate stations and the climatic areas developed using the Theissen polygon method is presented in Figure 4-1.

4.3 Cropping Patterns
Cropping patterns are available from two sources: the United States Department of Agricultural (USDA) 1992/1997 Census of Agriculture (USDA, 1997) and the Wyoming Agricultural Statistics for 2000 (WASS, 2002). A summary of the published cropping patterns and distributions are presented in Table 4-4, while the USDA cropping distribution by County is shown in Figure 4-2.
In general, for purposes of the modeling effort, the USDA values were used as the cropping pattern for the irrigated lands. The USDA values were used because they represent averages of more than one year within the study period (1973-2001), as compared with the Wyoming Agricultural Statistics, which represent only one year at the end of the study period. In addition, for certain climatic stations such as Sunshine and Dubois, it is recognized that many of the crops that are shown in the County-wide cropping patterns are not grown. Therefore, within these two polygons, it was assumed that only hay and alfalfa are grown (at the same distribution as without the remaining crops). Then, the cropping patterns for the remaining stations were modified so that the county-wide cropping pattern remains consistent.

4.4 Full Supply Crop Irrigation Requirement
Based on the cropping patterns and crop irrigation requirements for the climatic station polygons, the CIR for each of the irrigated lands polygons was calculated. A summary of the CIR for the lands within the Wind/Bighorn River Basin Plan is shown in Table 4-5. These CIR values represent the theoretical maximum crop irrigation requirement calculated using the methodology above, and is considered the Full Supply irrigation requirement for purposes of the model.

The Crop Irrigation Requirement represents the theoretical amount of water that is needed by the crop. Water is transported from the river to the crop through a series of conveyance facilities and on-farm facilities. These facilities lose a portion of the water that is transmitted through them before the water reaches the crops due to headgage leakage, evaporative losses, seepage, etc. These inefficiencies must be accounted for in determining the monthly diversion requirement for any crop.
4.5.1 Overall Efficiencies
Overall Efficiency is typically represented as the product of the conveyance efficiency and the on-farm efficiency. Conveyance efficiencies represent the efficiencies of the canals and/or pipelines that transmit the water from the diversion headgate to the farm turnout. Conveyance efficiencies typically vary from 65 to 90 percent, with open channel distribution systems generally having lower efficiencies and pipe systems generally having the highest efficiencies (SCS, 1993 and WWDC, 1999). Distribution system length, soil types, lining types, canal cross section and condition of structures can all have an affect on conveyance efficiencies. The on-farm efficiency represents the efficiency of applying water to the field from the farm turnout to consumptive use by the crop. On-farm efficiencies typically vary from less than 30 to nearly 65 percent, based upon the type of irrigation practices (SCS, 1993). Flood irrigation typically experiences lower efficiencies while sprinkler systems represent higher efficiencies.
Overall efficiencies are typically difficult to estimate. This study has relied upon Overall Efficiencies estimated from previous reports and from standard sources. For the Reservation area, efficiencies are taken from a study conducted by the SCS (1992), which estimated efficiencies for several areas within and in the vicinity of the Wind River Reservation. The SCS developed both annual and monthly overall efficiencies. For the remaining study area, efficiencies were based upon conveyance efficiencies reported by water users within the basin (WWDC, 1999), and typical field and application efficiencies estimated by the SCS (1993). Efficiencies typically vary by month due to antecedent moisture in banks (there is more moisture in the banks later in the season, thus there is less seepage from the canal), operational conditions, etc. Therefore, the efficiencies were varied by month using the same distribution as the monthly efficiencies calculated by the SCS for the Reservation. Table 4-6 presents the monthly and annual overall efficiencies used in the diversion requirement calculations.

Notes:4.5.2 Full Supply Diversion Requirement
- From (SCS, 1992).
- Based on average conveyance efficiencies from 1999 Irrigation System Survey Report (WWDC, 1999), large blocks with some lined canals and pipelines, and adequate management (SCS, 1992). Monthly distribution from (SCS, 1992)
- Based on average conveyance efficiencies from 1999 Irrigation System Survey Report (WWDC, 1999), small systems with unlined canals and sufficient management (SCS, 1993). Monthly distribution from (SCS, 1992)
- No consumptive use within month.
Based upon the crop irrigation requirements and overall irrigation efficiencies, Full Supply diversion requirements were calculated for the irrigated lands. The diversion requirement is calculated as the crop irrigation requirement divided by the efficiency of the system. The estimated Full Supply diversion requirements by sub-basin are shown in Table 4-7. As expected with the wide variations in efficiencies, the unit Full Supply diversion requirements expressed as acre-feet per acre also vary.

Section 5 - Summary and Conclusions
The purpose of the analysis summarized in this Technical Memorandum was to document the status of historical and current agricultural water use within the Wind/Bighorn River Basin and to document the methodologies used to develop data necessary for the River Basin simulation models. A summary of the irrigated lands identified in this study as well as those documented in the 1972 Water Plan (SEO) is presented in Table 51. The current estimate of irrigated lands is approximately 54,000 acres, or approximately 10 percent, greater than the estimate of 1972 irrigated lands in the 1972 Water Plan. In addition, the estimate of idle lands is approximately 44,000 acres, or approximately 150 percent, greater than the estimate of idle lands in 1972. The differences could be due to increased lands under irrigation, but are more likely a difference in estimation techniques. For instance, the definition of idle lands in the 1972 Water Plan (lands purposely left idle for any given year or lands on which a crop was planted but not harvested) is much more strict than used in this study (basically any land with a water right not currently irrigated but that has shown any signs of past irrigation). Another factor is that the current basin plan considered all lands in the Wind River Irrigation Project that were given water rights as either irrigated or idle, whereas the 1972 Water Plan may have not.

Total | 538,830 | 641,500 | 688,990 |
Direct comparisons of consumptive use are not as easy because the current basin plan did not calculate consumptive use for the Popo Agie basin. However, a comparison of unit consumptive use (ac-ft/ac) can be made. The 1972 Water Plan calculated a total consumptive use for the 538,830 acres as 1,028,500 acre-feet, or approximately 1.91 acre-feet per acre. As shown in Table 4-5, the current basin plan calculated a consumptive use of 1,165,000 acre-feet for the 600,400 acres used in the model, or approximately 1.94 acre-feet per acre, which agrees very closely to the consumptive use calculated in the Water Plan.
As a major purpose of the irrigated lands and consumptive use calculations in this study was to provide data for overall basin planning, a conservative approach was taken. The conservative approach ensures that all lands with currently or recently active water rights are considered in the water needs analysis and are considered when available surface water is determined. More detailed analyses could be performed once specific projects are identified.
