At present, interests of the different recreationists – fishermen, canoers, campers, and riverside property owners – conflict. The conflict results from the face that the...

Water resources data for the 1974 water year for Michigan include records of data for the chemical and physical characteristics of surface and ground waters. Data on the quality of surface water (chemical, temperature, and sediment) were collected from designated sampling sites at predetermined intervals such as once-daily, weekly, monthly or less frequently, and at some sites data were...

The Blue Earth River Watershed in Minnesota includes 3,106 square miles of land surface, which varies from fairly flat to gently rolling. The drainage extends south to include an additional 450 square miles in Iowa. The western, southern, and eastern boundaries are end moraines formed by Pleistocene glaciers. Major streams have eroded channels 40 to 75 feet deep in headwater regions and...

The Rum River, a tributary of the Mississippi River, drains an elongate area of about 1,550 square miles. The source of the Rum River is Mille Lacs Lake. Much of the northern half of the watershed is forested, and there are large areas of swampland. Population is most concentrated in the southern half, where agriculture is the dominant economic activity. Except for scattered Precambrian...

The lower St. Croix River watershed is an elongate area of about 930 square miles bounded on the east by the St. Croix River. The St. Croix River forms the Minnesota-Wisconsin boundary along the eastern side of the watershed. Additional drainage to the St. Croix River includes areas of about 2,500 square miles upstream in Minnesota and about 4,340 square miles in Wisconsin. At the...

Surface-water records for the 1973 water year for gaging stations, partial-record stations, and miscellaneous sites within the State of Michigan are given in this report. For convenience there are also included records for a few pertinent gaging stations in bordering States. The records were collected and computed by the Water Resources Division of the U.S. Geological Survey, under the...

Low-flow characteristics of Wisconsin streams at 415 sewage -treatment plants are presented in this report. The low-flow characteristics presented are the annual minimum 7-day mean flow that occurs on the average of once in 2 years (Q7, 2) and the annual minimum 7 -day mean flow that occurs on the average of once in 10 years (Q7, 10). The low-flow characteristics at most sewage-treatment...

The Marquette Iron Range is presently ( 1973) the second largest iron mining district in the United States. Commercial iron deposits, now mostly concentrating-grade ore, are in the Negaunee Iron-formation, which is part of a thick sequence of metasedimentary rocks of Precambrian X age. These rocks are preserved in the west-trending Marquette synclinorium, and are flanked to the north and...

This report describes the physical environment, availability, distribution, movement, quality, and use of water in the upper Wisconsin River basin as an aid in planning and water management. The report presents general information on the basin derived from data obtained from Federal, State, and local agencies, New field data were collected in areas where information was lacking. More...
