	*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 ProtectionÕs 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 Òmost at riskÓ 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 1920Õs 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 1930Õs such as copper sulfate treatments and hypolimnetic aeration with little long-term success.
