B. W. Drost, K. J. Whiteman
1986, Water-Resources Investigations Report 84-4326
A 2-1/2 year study of the Columbia Plateau in Washington was begun in March 1982 to define spatial and temporal variations in dissolved sodium in the Columbia River Basalt Group aquifers and to relate these variations to the groundwater system and its geologic framework. This report describes the geologic framework...

1986, Water-Resources Investigations Report 85-4002
The Lake Miona area, in northeast Sumter County, is characterized by karstic depressions that contain lakes, ponds, and marshes that drain vertically to the upper Floridan aquifer. Lake Miona, Black Lake, and Cherry Lake are the prominent water features of the area. When the lake levels are lowest, the lakes...
Hydrogeologic and water-quality characteristics of the Red River-Winnipeg aquifer northwestern Minnesota

1986, Water-Resources Investigations Report 84-4111
The Red River-Winnipeg aquifer of Ordovician age occupies a depression in the Proterozoic crystalline bedrock of northwestern Minnesota. The Winnipeg Formation, which underlies the Red River Formation, consists of two units: A lower shaley mudstone and an upper medium-grained sandstone. The Red River Formation consists of a lower dolomitic, dark-gray...
