Written by an assistant on the Geological and Natural History survey of Minnesota, this paper discusses the geological origins of the Minnesota River Valley. After providing a general view of the modern-day makeup of the valley (e.g., rock formations, bluffs, and tributaries), the author explores in more depth its condition during and after the Ice Age.

This management plan, one of a series of river-segment plans prepared to fulfill the Federal Water Pollution Control Act Amendments of 1972, was intended to develop an implantation strategy for improving water quality in the Blue Earth River subbasin o f the Minnesota River. The plan includes a description of the area (location and boundaries, water-quality classification), point-source discharges (municipal, industrial, and livestock feedlot), and an abatement schedule for noncompliant dischargers. A river-segment map is appended.

This survey of twenty-four Minnesota rivers, including the Minnesota, was conducted to determine physical characteristics and eligibility for inclusion in a state recreational river system. The study recommended that the Minnesota not be included in the system because the degree of development along its banks removed it from wilderness-river consideration and the nature of its flow meant that it is only intermittently canoeable.

This overall plan was designed to provide a basis for the conservation, preservation, and development of water resources in the Lac Qui Parle-Yellow Bank Watershed District. The plan includes a description of the district (e.g., location, geology, and sub-watersheds), district objectives, watershed problems and plans for solution (e.g., flood control, drainage, and water quality), and the policy under which works of improvement are pursued. Various maps are appended.
