Eutrophication BOD and Eutrophication -rapid succession in a body of water because of an increase in biological productivity (oligotrophic lakes and rivers have clear water and low biological productivity) -low nutrient levels -high nutrient levels good light penetratio poor light penetration -high dissolved oxygen low dissolved oxygen deep waters shallow waters -low algal growth -high algal growth small mouth bass, lake trout carp bullhead, catfish pike, sturgeon, whitefish (a)Oligotrophic lake (b)Eutrophic lake
