Documentation of a mass emergence of Hexagenia mayflies from the Upper Mississippi River

Article written by Calvin R. Fremling regarding a specific mayfly emergence on July 8, 1966 at Winona, Minnesota. Includes locations around the city such as Levee Park (emergence resulted in a shutdown of carnival equipment operating for Steamboat Days) and the John A. Latsch Wagon Bridge. Figure 1 shows a heavy swarm of mayflies covering the bridge and the author\u27s car. Summary: This report documents a mass Hexagenia mayfly emergence from the Upper Mississippi River, so that others may know of the magnitude of the phenomenon if Hexagenia populations are further reduced by pollution along the Upper Mississippi River. Fremling is credited as: Winona State College, Winona, Minnesota. Article reprinted from Transactions of the American Fisheries Society, volume 97, number 3, 19 July 1968. 5 pages. Part of the Cal R.

The Impact of Man on the Ecology of the Mississippi River

Essay written by Calvin R. Fremling in a pamphlet of unrelated work including drawings and an essay about poetry. Summary: ...the meandering Mississippi of yesteryear has been transformed by man into a narrow, channelized, polluted, sinuous ditch from St. Louis to the Gulf of Mexico. Early channelization projects on the Upper Mississippi have been overshadowed by the impoundment projects of the 1930\u27s. The navigation dams, from Minneapolis to St. Louis, have made the old free-flowing Mississippi into a series of large, well-fertilized, silted lakes, through which an appreciable current still flows. The main stream is punctuated by navigation structures which provide large surface areas for habitation by certain invertebrates. In areas where pollution is not severe, man has temporarily increased the carrying capacity of the Upper Mississippi River for burrowing mayflies, hydropsychid caddisflies and most species of river fish. He has lowered the carrying capacity of the river for clams. Extreme pollution in the Twin Cities area has transformed the river into an open sewer as far south as Hastings. Man\u27s continued abuse of the watershed, the attendant elevation of the flood plain, and constriction of the flood plain will increase the severity of future floods.
