Digitized edition from print [produced by Environment and Climate Change Canada]. Includes bibliographical references. "Hypereutrophic lakes represent the ultimate stage of the eutrophication process, which is ecologically unstable and irreversible. Excessive input of nutrients from external sources leads to the "vicious circle" phenomenon, where the internal input of nutrients regenerated from the anoxic sediments is sufficient enough to drive the lake productivity by itself. Different strategies and radical in-lake measures are needed to rehabilitate them to some use. A summary of these is presented"--Page 1. gccst Lakes gccst Ecology gccst Restoration Canada.
