The milk marketing area of Omaha, shown on Figure 1, includes all or parts of 12 Nebraska counties and 20 counties in western Iowa. Normally 80 percent of Omaha's fluid milk needs comes from the region outlined as Omaha's milk marketing area. Southwest of Omaha, the major milk producing counties of Gage, Jefferson and Lancaster are part of the Lincoln milk marketing area. And to the northwest of Omaha are some of the heaviest bulk-milk producers i.e., milk used for manufactural purposes--dry milk products, etc. Therefore, even though Wayne, Pierce, Antelope and Cedar counties are the major milk producers in Nebraska, they are not included in the Omaha milkshed. Likewise, the major milk producing counties in western Iowa are part of the Sioux City milkshed.
