Hydrologic and water-quality characteristics were determined for a wetland being used for tertiary treatment of wastewater in St. Joseph, Minnesota. The wetland consists of spruce-tamarack fen and a cattail marsh, with the wastewater being discharged into the fen, and the fen draining into the marsh. The wetland is underlain by flat-lying glacial outwash that ranges from 0 to greater than 20 m in

Two sediment cores were taken from the Rochester Basin of eastern Lake Ontario and analyzed for the radionuclides 210Pb and 137Cs and several high molecular weight chlorinated hydrocarbons (CHs). The two sites are geographically proximate but differ in sedimentation rate, permitting sedimentation-dependent processes to be factored out. The 210Pb chronology showed a mixed depth of 3-5 cm and an int

A three-step analysis of the cost-effectiveness of the streamflow-gaging program in Minnesota is documented in this report. In the first step of the analysis, the data uses and funding sources were identified for the 96 continuous-record streamflow-gaging stations operated in 1985. Nineteen sources of funding and 42 uses were identified for the data collected in this program. Two stations were ide

Sixteen lakes in the city of Eagan, Minnesota, were sampled during 1982-83 to detect water-quality changes that might have occurred because of urbanization since a previous study conducted during 1972-78. Each of the lakes was sampled five times to determine pH, specific conductance, dissolved oxygen, water temperature, transparency, and concentration of dissolved chloride. Three determinations of

Water resources in the White Earth Indian Reservation meet the present (1988) needs for potable supply and other household uses and provide valuable ecological, recreational, and aesthetic benefits. Total annual water use in the Reservation is about 460 million gallons per year. Domestic supply from privately owned wells and municipal systems accounts for roughly three-fourths of the water use, an

Water resources in the Fond du Lac Indian Reservation meet the present (1987) needs for drinking-water supplies and other household uses with respect to water quality and quantity, and provide valuable ecological, recreational, and aesthetic benefits. Total annual water use in the Reservation is about 36.5 million gallons per year and per capita use is about 100 gallons per day. Practically all th

During March through October 1986, 52,560 acre-feet of water passed the continuous-record stream gaging station on the Clearwater River near Clearbrook, Minnesota, 4.8 river miles upstream from the Red Lake Indian Reservation. Flow at the downstream boundary of the Reservation totaled 93,770 acre-feet. The increase in Clearwater River flow in the reach bordering the Reservation equaled 32,950 acre
