"Humboldt Lake, a hypertrophic prairie lake typical of many found on the Great Plains of North America, is usually ice covered from early November to about mid-May. The lake is an important recreational fishery, now mainly stocked with walleye. It has a high risk of experiencing fish kills because of the very large cyanobacterial blooms that develop in it, the high rates of algal and bacterial production and the high concentrations of ammonia and dissolved organic matter. Following the collapse of cyanobacterial blooms, shallow prairie lakes are known to undergo periods of anoxia that can lead to summer fish kills"--Abstract. gccst Lakes gccst Water quality gccst Fisheries Canada.
