Description
Article written by Cal R. Fremling regarding mayflies on the upper Mississippi River, population and distribution data over a 7-year period, and pollution levels of various river sections indicated by presence (or lack) of mayfly mass emergences. Fremling is credited as: "Winona State College, Winona, Minnesota." Abstract: "Hordes of mayflies emerge during the summer months from most sections of the Upper Mississippi River, thus creating nuisance problems for shoreline residents and river traffic. The presence of these pollution sensitive forms indicates, however, that the river is more river-like than sewer-like in a given area." Article copied from Science, 27 November 1964, pages 1164-1166. 3 pages. Part of the Cal R. Fremling Collection.
