Lake St. Clair and St. Clair and Detroit Rivers chemical and physical characteristics data for 1974

Water samples at standard depths, bottom sediment, and meteorological data were collected in Lake St. Clair and in the St. Clair and Detroit Rivers at established stations in the course of nine lake and river cruises during the 1974 open-water season. The sampling program and analytical methods are described. Chemical characteristics of the water and bottom sediment are listed by cruise for each station and sampling depth. Wind, wave, and sediment data are listed by cruise for each station. The statistical summaries showing lake-wide means, standard deviations, and sample sizes of selected variables are presented by depth for each cruise period.
