<br />3. The latest aerial photography available will be secured. All <br />photos will' be on a scale of 8" = 1 mile. These photos will be <br />used to make the field by field inventory. Study area wide wall <br />maps on a scale of 1/2" = 1 mi Ie wi i 1 be used to del ineate areas to <br />be surveyed and to keep track of progress. An updated ownership <br />plat book would be useful. <br /> <br />4. All available research and basic data applicable to the study <br />program evaluation will be assembled and reviewed. Sources for <br />this data are the Bureau of Reclamation, Agriculture Research <br />Service and.data gathered from other study areas. <br /> <br />5. The local Soil Conservation Service Soil Scientist will develop <br />intake family classifications for the soils in the study area. <br />Information gathered in the study will be used to update the <br />irrigation guide for the area. <br /> <br />6. The District Conservationist and the study team members will <br />determine what information needs to be gathered and what procedures <br />will be followed in order to arrive with the desired results for <br />the study. Worksheets will need to be made up to reflect the study <br />items. <br /> <br />7. Using the worksheets developed for the study area, a field by field <br />inventory of at least 60% of the study area wi 11 be made by interviewifl,! <br />the farmers and ranchers in the area. The selected areas will <br />represent a cross-section of the soils, crops, size, type of operation <br />and where salt problems and salty discharge is most apt to occur. <br /> <br />8. Make an assessment of socioeconomic, institutional, environmental <br />and agronomic factors in the basin. The assessment is for present <br />condition as well as for possible future conditions. <br /> <br />9. Complete an investigation of the ground water and drainage pattern <br />in the area, taking into account their relationship to each other. <br />Using the data gathered, determine how salt loadings occur in the <br />study area. The Agricultural Research Service should be in a <br />position to supply quite a bit of input into this item. <br /> <br />10. Irrigation efficiencies for the study area will need to be determined. <br />The Uncompahgre Valley Water Users' Association in cooperation with <br />the Bureau of Reclamation is in the process of scheduling irrigation <br />needs for several interested water users. Maximum use of this data <br />wi 11 be made. <br /> <br />11. Using the gathered inventory data, a water and salt budget can be <br />computed to reflect present conditions. Based on desired future <br />management conditions, a water and salt budget for future conditions <br />can be developed. <br /> <br />003:1i}O <br /> <br />15 <br />
