<br />C"";) <br />co <br />C"? <br /> <br />Crop distribution will be similar to evaluation area A and average crop <br />yields will be slightly lower due to the estimated shorter growing season. <br /> <br />Evaluation Area F <br /> <br />Evaluation area F is comprised of 177 acres of presently irrigated land <br />located in Dry Elk Valley, interspersed with lands of evaluation area E. <br />Soils are similar to evaluation area E but slopes are steeper (6 to 12 <br />percent), There is a small acreage of wet land but it is anticipated that <br />the proposed project drainage will correct this condition. <br /> <br />Lands in this evaluation area will also be served by direct diversion into <br />the Grass Valley Canal from East Rifle Creek. The proposed project will <br />supply approximately 1.9 acre-feet per acre additional irrigation water <br />to these lands. <br /> <br />It is anticipated that the same crop distribution will occur on these <br />l~.ds as on lands of evaluation area B. Crop yields are estimated slightly <br />lower than those in evaluati on area B. The differences in crop yields will <br />be similar to those between evaluation areas A and E. <br /> <br />Evaluation Area G <br /> <br />This evaluation area comprises 341 acres of new land in Dry Elk Valley. <br />Soils and slopes are similar to evaluation area E. Climate and crop yields <br />with project are the same as for evaluation area E. Water to be furnished <br />by the proposed project is approximately 2.7 acre-feet per acre. <br /> <br />Evaluation Area H <br /> <br />Evaluation area H is comprised of 346 acres of new land in Dry Elk Valley. <br />Soils and slopes are similar to those in evaluation area F. Climate and <br />crop yields with project are the same as evaluation area F. Water supply <br />to be furnished by the proposed project is approximately 2.7 acre-feet <br />per acre. <br /> <br />Soils Inventory <br /> <br />Sources of Data <br /> <br />Soil information used in the reappraisal of the Silt project was obtained <br />frCl1\ the Soil Conservati on Service, Agricul tural Research Service and <br />Bureau of Reclamation. A soil survey of the project was completed by the <br />Soil Conservation Service, Laboratory data on project soils were furnished <br />by the Agricultural Research Service and the Cooperative Soil Survey Labo- <br />ratories in Fort Collins, Colorado. The Bureau of Reclamation supplied <br />land classification field sheets and laboratory data on the chemical and <br />physical properties of project soils. Information on water intake rates <br />of soils was obtained from ~linder infiltrometer tests on selected sites <br />of dominant soils. <br /> <br />- B - <br />
