This report follows the study of uranium and thorium potential of the Precambrian rocks of northern Wisconsin and the western half of the Upper Peninsula of Michigan.

Report and Geographical Survey. Report uses a streamflow-routing model to simulate the daily flow at Park Falls over the next ten years and includes several illustrations 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 introduction: This report presents practical and useful sediment-yield information for Wisconsin. Measured and estimated sediment yields are supplemented by information on suspended-sediment concentration and particle size of suspended and bed material for 84 sites in the State. To expand the usefulness of these data, an additional section in the report presents a method to estimate or predict sediment yields in ungaged streams.

Interview with John Kuhn, a Navy WWII veteran from Winnebago, Minnesota. Kuhn discusses his experience at Pearl Harbor during the Japanese attack on December 7th, 1941, including joining the Navy in 1940 and training, attachment to the USS Thornton, radio duty on Ford Island, the events of the attack, and the following evening.
