Book excerpt: Excerpt from Dry Farming in Oregon In the Blue Mountain and Central Oregon divisions (see map), hitherto devoted largely to the production of livestock and of hay and grain by means of irrigation, large areas of lands that cannot be irrigated have been in recent years and still are being brought into production by means of the dry farming system. In the three different divisions of Eastern Oregon, shown on the map, the conditions as to soils, rainfall, elevation, and growing season, and their effect upon dry farming production, vary considerably. In the Columbia Basin region, with the exception of Umatilla County, the average annual rainfall is about 11 inches, the average elevation 2000 feet, and the average growing season 150 days. In the Blue Mountain region, the average annual rainfall is about 18 inches, the average elevation 3000 feet, and the average growing season 120 days. In the Central Oregon division, the average annual rainfall is 11 inches, the average elevation 4000 feet, and the average growing season 100 days. The rainfall in Umatilla County(15 to 25 inches) is considerably higher than that in the rest of the Columbia Basin, owing to the proximity of the Blue Mountains. Thus it may be seen that in the Blue Mountain region, the large rainfall permits heavier production on the dry farm, while in the Columbia Basin the rainfall is so low as to require the most careful methods. In Central Oregon, on the other hand, the elevation and short growing season make frosts the most critical factor in production. Throughout Eastern Oregon, the evaporation is rather high, averaging about 45 inches from a free water surface, while the distribution of the rainfall is not especially favorable to crops, owing to the very scanty precipitation during the summer months.
