Water-Resources Investigations Report 78-48

This report focuses on the Nevin Wetland near Madison, Wisconsin and presents a detailed report on the quality of the ground-water, it's components, and what environmental factors influence these components. It includes maps and tables

Recycling water within the local ground-water system is an effective means to increase quantity and control water temperature of the water supply and to control or avoid environmental pollution. A fish-rearing facility, operated for 15 months, returned water to the local ground-water system through an infiltration pond and recycled 83 percent of its water supply. For each 100 gallons pumped the net stress on the aquifer was equivalent to withdrawing 17 gallons. Despite recycling, nutrient content and temperature of the water supply were acceptable throughout the study period. The rearing-facility nutrient output ranged from 1 to 2 pounds of nitrate-nitrogen per day, but nitrate-nitrogen levels in the water supply remained below 4 mg/1. The water temperature ranged from 7°C to 14°C. Mathematical relations developed show that acceptable nitrate-nitrogen levels and water temperatures nearly optimum for salmonid rearing could be maintained during full-scale hatchery operation

From abstract: This report presents estimated annual and monthly water budgets for lake Wingra and the adjacent wetland area for January 1972 through September 1977. Annually, inputs from precipitation, surface runoff, and ground-water inflow are approximately equal (31, 34, and 35 percent, respectively). Outputs include outflow from the lake into Murphy Creek (70 percent), evotranspiration from the lake and wetland (26 percent), and ground-water outflow (4 percent)

Wetland diversity: The limits of generalization.

Generalizations are important tools in learning about complex phenomena such as wetlands. Geography teachers at all levels use generalizations in order to help students grasp the discipline\u27s major themes. One of geography\u27s major themes is that of place, and that includes uniqueness of place. Accordingly, it is important to recognize the diversity of wetland environments because different wetlands provide different sets of ecological functions and values to people. Successful attempts to merge the study of wetlands and geography must weave together discussion of generalizations about wetlands with attempts to foster some appreciation for wetland diversity
