	*The most prominent and visible water quality issues in Maine lakes come as a result of algal blooms.
	Blooms often occur as the result of increased nutrients, specifically phosphorus and may result in: green-colored and bad-tasting water, reduced transparency, a build up of scum, and foul odors*
	*Repeated algal blooms can result in fish kills and loss of the coldwater fishery.
	*Water quality has become a relevant factor in the consideration of lakes by visitors and homeowners, and produces a significant influence on the economy and population of lake communities
	*Togus Pond is included on Maine Department of Environmental Protection�s list of 38 Maine lakes that commonly bloom; and is one of 13 commonly blooming lakes located in Kennebec County.
	*Togus Pond is also listed as one of the �most at risk� lakes in Maine in terms of potential development.
	*Long time residents of the Togus Pond area have reported that summer algal blooms commonly occurred in the lake as early as the 1920�s and frequent blooming has continued throughout the past several decades
	*In response to the frequent algal blooms experienced by Togus Pond, various remediation techniques have been attempted since the late 1930�s such as copper sulfate treatments and hypolimnetic aeration with little long-term success.
