The Flood Disaster Protection Act Of 1973: A Rational Approach To Flood Damage Prevention, Larry J. Wilson Oct 1975

The Flood Disaster Protection Act Of 1973: A Rational Approach To Flood Damage Prevention, Larry J. Wilson

IUSTITIA

Throughout history, man has utilized rivers for water supply, transportation, power generation, and waste disposal. This strong relationship has encouraged the location of human settlements near rivers and streams despite the risk of periodic flooding. The modern technology of transportation and public services has reduced the necessity for riverside locations, but the development of flood plains in urban areas has continued, resulting in the periodic loss of human life and property when flooding has occurred. Within the United States, flooding has taken over 5000 lives in the last fifty years and causes an estimated $1.25 billion in property damages annually.' …


Limnological Observations On A Small River, Donald G. Kaddatz Jan 1975

Limnological Observations On A Small River, Donald G. Kaddatz

Journal of the Minnesota Academy of Science

Limnological conditions were studied in the Snake river at Mora, in east-central Minnesota, over a 13- month period. Sampling stations were established above and below the sewage outfall from the city of Mora to assess the river's physical and chemical parameters. Seasonal changes and fluctuations related to discharge flow were observed and recorded.


Effect Of Feedlots On Water Quality, Ronald D. Cheetham, Alan J. Holmes, David Borresen Jan 1975

Effect Of Feedlots On Water Quality, Ronald D. Cheetham, Alan J. Holmes, David Borresen

Journal of the Minnesota Academy of Science

The effect of feedlot runoff on water quality was examined. Samples were collected from river feedlots and offshore from lake feedlots and compared with samples from appropriate control sites. Bacterial contamination, as measured by the total coliform test over two successive summers, exhibited significant variation between feedlot and control sites. Coliform levels at lake sites adjacent to feedlots were double the levels at control sites; while in river systems average coliform levels downstream from feedlots were approximately 17 times the upstream controls.
