This technical paper examines the relative influence of wind-driven waves and recreational boat wakes on sediment resuspension in Wisconsin inland lakes. Drawing on published research, hydrodynamic calculations, and Wisconsin Department of Natural Resources lake data, the document applies scaling methods to estimate wave height, wavelength, sediment mobilization depth, and the spatial extent of wind-driven wave action on typical inland lakes. It also compares the relative areas influenced by wind waves and wake boat operation under a range of representative conditions.

The paper reviews research related to wind-wave generation, wake boat hydrodynamics, sediment transport, and lake morphology, and discusses the applicability of previous field studies to Wisconsin lakes. It presents calculations, supporting references, and technical responses to potential methodological critiques while examining the implications of wind-driven processes, recreational boating activity, and water depth for sediment resuspension and waterway management. The document is intended for researchers, waterway managers, policymakers, and others interested in the scientific and technical considerations associated with recreational boating and inland lake management.
