NWRI contribution ; no. 01-212 Digitized edition from print [produced by Environment and Climate Change Canada]. Includes bibliographic references. "Eutrophic hardwater lakes on western Canada's Boreal Plain are characterized by late summer cyano-bacterial blooms, hepato- and neurotoxin release during blooms, high macrophyte standing crop, and dissolved oxygen (DO) depletion that can kill aquatic organisms (S: Prepas, 1990; Kotak et al., 1993). These conditions have been at least partially induced by human activities such as land clearing for agriculture and recreational development (Allan et al., 1980; Mitchell & Prepas, 1990; Hall et al., 1999; Prepas & Serediak, 1999)"--Introduction.
