| Abstract: | The settlement and development of South Dakota and the Big Sioux River basin have been closely related to water resources. The climate is a continental type and annual precipitation in the basin is about 23 inches. The area of the field trip lies within the Coteau des Prairies, a massive highland within the Central Lowlands Province. It is drained primarily by the Big Sioux River. The bedrock underlying the coteau is a series of Cretaceous sedimentary rocks and the Sioux Quartzite of Precambrian age. Wells in the Cretaceous Dakota Sandstone yield from 10 to 1,000 gallons per minute; the other bedrock formations generally yield less than 10 gallons per minute. The glacial outwash deposits on the coteau are generally excellent sources of ground water; the other glacial deposits, till and loess, are not dependable sources. (Woodard-USGS) |
