This technical critique evaluates the methodology, analysis, and policy conclusions of the 2023 Ashippun Lake Wake Study, which examined the effects of wake boat operations on wave heights, turbidity, and water quality in a small Wisconsin lake. The report reviews the study's experimental design, wave measurement methods, hydrodynamic comparisons, wind-wave equivalency calculations, statistical analyses, and interpretation of findings in the context of established scientific principles and published research.

The critique compares the Ashippun study with peer-reviewed literature on recreational boat hydrodynamics and wake generation, identifies methodological limitations, and discusses the implications of instrument selection, benchmark comparisons, wave energy calculations, and shoreline measurement techniques. It also examines the applicability of the study's conclusions to broader waterway management and policy decisions, providing a technical assessment intended for researchers, waterway managers, policymakers, and others evaluating scientific evidence related to wake boat impacts.
