Wisconsin has developed an assessment and listing methodology (WisCALM) for Clean Water Act reporting. WisCALM is a systematic process by which water (rivers, lakes and streams) condition is assessed and management options evaluated. WisCALM provides guidance for conducting general and impaired water determinations.

As required by s. 281.15(2), Wis. Stats., in adopting any water quality criteria for waters of the state, the Department is required to develop a technical support document. That document must include a description of the scientific data used; the margin of safety applied; the persistence, degradability and nature of the pollutant; and the nature and effects on the designated use.
