Factors controlling the evolution of salinity, productivity and ecological stability of eutrophic lakes in central North America : (a summary) / J. Barica.En13-5/90-13E-PDF

"This is an invited summary paper to be presented and published at the SIL Symposium on evolution of lakes to be held in Poznan, Poland in May 1990. It is based on Dr Barica’s past work on prairie lakes (Freshwater Institute, Winnipeg) conducted prior to his appointment to NWRI, Burlington. It analyzes controlling factors in formation of ionic composition and phytoplankton biomass of the prairie lakes (surface deposits and soils, erosion, topography, lake morphometry, groundwater composition, etc.) and concludes that it is the semi-arid climate and groundwater flow which explain the extreme variability in lakes salinity and production. However, the ecological instability of the lakes (algal collapses and resulting anoxia) is triggered by meteorological factors. The winter anoxia (winterkill) is the result of continental climate and governed by lake morphometry"--Management perspective.
