Book excerpt: Excerpt from Geology and Ground-Water Resources of the Lower Little Bighorn River Valley, Big Horn County, Montana: With Special Reference to the Drainage of Waterlogged Lands Surface water from the Little Bighorn River and Lodge Grass Creek is the principal source of water for irrigation in the area. Chemical analyses were made of 71 samples of water collected from several sources. Water from the Cloverly formation and the Parkman sandstone is soft and has a high sodium content. Although in the southern part of the area the water from these bedrock aquifers is suitable for domestic and many industrial uses, its high percent sodium makes it undesirable for irrigation. In general, the ground water from unconsolidated aquifers and the surface water are hard; the predominant ions in the ground water are sodium and sulfate and in the surface water are calcium, magnesium, and bicarbonate. The surface water from the perennial streams is best for irrigation, whereas ground water from the unconsolidated deposits is highly variable in mineral content and its suitability varies correspondingly. Ground water from the unconsolidated deposits generally is suitable for either irrigation or domestic use, but in a few localities the content of dissolved solids exceeds parts per million and the water is undesirable for most purposes.
