"This report summarizes water quality assessment information submitted by the States to the U.S. Environmental Protection Agency (EPA) in 1990 under Section 305(b) of the Clean Water Act. The States based their water quality assessments on data collected in 1988 and 1989 using physical, chemical, and "evaluative" approaches such as sending questionnaires to fisheries biologists and analyzing land use data."--Page xiii
