Lake productivity falls into three categories based upon nutrient status and overall production:
	-Oligotrophic
	-Mesotrophic
	- Eutrophic
	The image pictured with the mountain in the back is an extreme example of an oligotrophic lake
	-the water is very clear, has high visibility and very limited production
	The image pictured with the trees is an example of an extremely eutrophic body of water
	-the water is very cloudy and is characterized with high levels of production
	Mesotrophic lakes fall between these two categories
	Majority of Maine lakes are mesotrophic making them moderately productive
