Effects of reclamation on an urban winter-kill lake at Winona, Minnesota, U.S.A.

Article by Calvin R. Fremling regarding severe winter kills at Lake Winona and their results on various fish populations. From introduction: Lake Winona (Fig. 1), which lies within the City of Winona in southeastern Minnesota, is highly eutrophic because it receives nutrient-rich urban runoff and has stored erosion products from surrounding agricultural land. Severe winter kills in 1965 and 1969 allowed rough fish to dominate the lake until 1973, when it was reclaimed to create a sport fishery, mainly for children, the elderly and handicapped. Reclamation has caused complex limnological changes. Article originally from Verhandlungen des Internationalen Verein Limnologie (Verh. Internat. Verein Limnol.), volume 23, January 1988.
