摘要

This report presents the results of a study conducted by the Department of Geography at the University of North Dakota in cooperation with the U.S. Fish and Wildlife Service and the North Dakota Department of Health to examine water quality in the vicinity of Lake Alice National Wildlife Refuge. The purpose of this study was to 1) determine the seasonal variation of surface water quality of Lake Alice National Wildlife Refuge and its tributaries; 2) determine trace element and nutrient concentrations in sediment; and 3) complete a land cover assessment of the Mauvais Coulee and Calio Coulee watersheds. Lake Alice National Wildlife Refuge lies in northeastern North Dakota, and is part of the headwaters area for the Devils Lake basin. The two main tributaries to Lake Alice and the refuge are Mauvais Coulee and Calio Coulee. These tributaries flow primarily through cropland (small grains, row crops, hay) and have three large (8,000 20,000 hogs) concentrated animal feeding operations (CAFOs) within their watersheds. The closest waste management area for the CAFOs is within 1.4 miles of the Lake Alice refuge boundary.
