Model Studies Of The Cooling Water Outlet Channel From The Allen S. King Generating Plant To Lake St. Croix

Abstract

The Northern States Power Company is building the Allen S. King Generating Plant, a thermal plant, on Lake St. Croix between Stillwater and Bayport, Minnesota. Operation of the plant requires that water be drawn from Lake St. Croix, used for condenser cooling purposes. and then discharged essentially unchanged except with a higher temperature, back into Lake St. Croix at a location downstream from the intake. The first unit of the plant, requiring 660 cfs of condenser cooling water, is now under construction. It is planned to add a second unit later making a total requirement for condenser cooling of 1500 cfs. Pioneer Service and Engineering Company is designing the plant.
