Activated carbon was effective in removing fish toxicants and anesthetics from water solutions. Its capacity to adsorb 3‐trifluoromethyl‐4‐nitrophenol (TFM), antimycin, Noxfish(R) (5% rotenone), Dibrom(R), juglone, MS‐222, and benzocaine ranged from 0.1 to 64 mg per gram of carbon. The adsorptive capacity (end point considered as a significant discharge) of activated carbon for removal...

Irrigation has given a substantial boost to the economy in the Brooten-Belgrade and Lake Emily areas of Minnesota. The surficial outwash aquifer is capable of yielding sufficient quantities of water for irrigation over half of its area; the remaining part may be supplied by deep aquifers. Buried glacial outwash and Cretaceous sand aquifers, as thick as 50 feet occur to depths of 300 feet...

Recycling water within the local ground-water system can increase the quantity of water available for use, control or avoid environmental pollution, and control temperature of the water supply. Pumped ground water supplied a fish-rearing facility for 15 months, and the waste water recharged the local ground-water system through an infiltration pond. Eighty-three percent of the recharged...

The purpose of this report is to provide information on the extent , depth, and frequency of flooding of the lower Yahara River in Dane County, Wis. The report contains discharge-frequency data for flood peaks, flood–frequency profiles, and the regional flood– (100-year flood) inundation limits for the lower Yahara River. The study reach is in southern Dane County extending from part of...

Ground water is the major source of water supply in Minnesota. The quantity, quality, and availability vary greatly throughout the State. This study describes the State's ground-water resources as found in each of seven major drainage basins. Water is obtained from Quaternary glacial deposits and bedrock aquifers. Most supplies are from the drift except in the southeastern and extreme...

Daily streamflows of the Flambeau River at Park Falls, Wisconsin , were simulated for a 31-year period. Streamflow was simulated using a streamflow-routing model. These simulated daily flows were analyzed for summer (June 1-October 31) low-flow frequency. The resultant 7-day, 10-year summer low flow is 260 cubic feet per second. The standard error of estimate for this 10-year-frequency...

The low-flow characteristics of the Pike River basin, Racine and Kenosha Counties were studied to determine the feasibility of Public Law 566 watershed-protection practices. Two seepage runs, one in October 1973, and the other in September 1974, showed that most of the low flow is combined treated-sewage and industrial cooling-water discharge. This effluent was 4.66 cubic feet per second...
