Abstract:

The Rockton Hydroelectric Project is a two-unit, 1,100 kW plant operated by South Beloit Water, Gas & Electric Company, a wholly owned subsidiary of Wisconsin Power & Light Company. The project's 1,000-foot spillway directs water from the main stem of the Rock River, down a 5,000-foot power canal to the project. During relicensing of the project, state and federal resource agencies directed the licensee to propose an operations scheme for providing a protected minimum flow in the main stem of the river. As the prime relicensing consultant to Wisconsin Power & Light, Mead & Hunt conducted field studies to assess the environmental impact of various minimum flows. Mead & Hunt then conducted economic analyses to determine the economic impact of various minimum flows. The economic and environmental analyses were combined to develop a recommended minimum flow, which will be provided in the Draft Application for Subsequent License.
