The Effect Of Cyanobacterium Gloeotrichia Echinulata In The Belgrade Lakes, Maine, Harriet T. Rothschild Jan 2016

The Effect Of Cyanobacterium Gloeotrichia Echinulata In The Belgrade Lakes, Maine, Harriet T. Rothschild

Honors Theses

Gloeotrichia echinulata is a cyanobacteria species that has been increasingly forming blooms in oligotrophic lakes in the Northeastern United States. The Belgrade Lakes in central Maine have experienced increasing blooms over the past decades. Long Pond and Great Pond in the Belgrade Lakes region are popular locations for summer tourism and year-round residents. Research into G. echinulata is important to the Belgrade community because of potential effects to water quality, public health, and recreation. Studying G. echinulata bloom density throughout the summer and how it may affect the phosphorous cycle, the nitrogen cycle, and the plankton community will help scientists …

Colby College Watershed Study: East and North Ponds (2011, 1999, 1996, 1991)

During the fall of 2011, the Colby Environmental Assessment Team (CEAT) studied the Serpentine connecting East Pond and North Pond. East and North Ponds are members of the larger seven-lake system known as the Belgrade Lakes, located in central Maine. There are over 5,500 lakes in Maine that contribute $6.7 billion to the economy annually through activities including boating, fishing, swimming etc. Additionally, Maine’s lakes are sources of municipal and agricultural water, act as flood buffers, and host a wide range of plant, animal, and fish life. Lakes in Maine are a crucial part society and should be studied and …


Impacts Of Shoreline Development On The Littoral Zone Of Great Pond, Problems In Environmental Science Course (Biology 493), Colby College, Colby Environmental Assessment Team, Colby College Jan 2010

Impacts Of Shoreline Development On The Littoral Zone Of Great Pond, Problems In Environmental Science Course (Biology 493), Colby College, Colby Environmental Assessment Team, Colby College

Colby College Watershed Study: Great Pond (2012, 2010, 1998)

The Colby Environmental Assessment Team (CEAT) investigated the littoral zone of Great Pond in the Belgrade Lakes region of central Maine. Data collection occurred in September and October and analysis followed in October and November of 2010. Physical, biological, and chemical parameters were assessed to examine the impacts of shoreline development on the health of the littoral community. The littoral zone and adjacent riparian areas were sampled to allow comparison of aquatic and terrestrial parameters among different levels of shoreline development.


A Watershed Analysis Of Pattee Pond: Implications For Water Quality And Land Use Management, Problems In Environmental Science Course (Biology 493), Colby College, Colby Environmental Assessment Team, Colby College Jan 2008

A Watershed Analysis Of Pattee Pond: Implications For Water Quality And Land Use Management, Problems In Environmental Science Course (Biology 493), Colby College, Colby Environmental Assessment Team, Colby College

Colby College Watershed Study: Pattee Pond (2008, 1992)

The Colby Environmental Assessment Team (CEAT) investigated the impact of land use patterns on the water quality of Pattee Pond in Winslow, Maine, during the summer and fall of 2008. Physical, chemical, and biological characteristics of water quality were analyzed to evaluate the current health of the lake. Data collected were compared with previous studies conducted by the Maine Department of Environmental Protection (DEP) and CEAT to examine changes in water quality and land use over time. Trends in Pattee Pond water quality suggest an improvement since the 1970s. However, the lake is still experiencing algal blooms resulting from phosphorus …

Land Use Patterns In Relation To Lake Water Quality In The Lake George And Oaks Pond Watersheds, Problems In Environmental Science Course (Biology 493), Colby College, Colby Environmental Assessment Team, Colby College Jan 2001

Land Use Patterns In Relation To Lake Water Quality In The Lake George And Oaks Pond Watersheds, Problems In Environmental Science Course (Biology 493), Colby College, Colby Environmental Assessment Team, Colby College

Colby College Watershed Study: Other Area Studies

There has always been an inexplicable wonder associated with the beauty of Maine lakes. In addition to their aesthetic value, lakes and ponds provide important habitats for aquatic and terrestrial wildlife. The attraction of the lake's natural beauty, however, can increase recreational pressures that may lead to human induced eutrophication. Lake George and Oaks Pond were chosen as the Colby Environmental Assessment Team's (CEAT) study sites due to the concern about potential human induced eutrophication of both water bodies. Lake George and Oaks Pond are situated in southern Somerset County, Maine, and experience heavy recreational and developmental uses. Neither water …


Land Use Patterns In Relation To Lake Water Quality In The Lake Wesserunsett Watershed, Problems In Environmental Science Course (Biology 493), Colby College, Colby Environmental Assessment Team, Colby College Jan 2000

Land Use Patterns In Relation To Lake Water Quality In The Lake Wesserunsett Watershed, Problems In Environmental Science Course (Biology 493), Colby College, Colby Environmental Assessment Team, Colby College

Colby College Watershed Study: Other Area Studies

The Colby Environmental Assessment Team (CEAT) engaged in an extensive data collection and analysis effort from September to December of 2000 to produce a comprehensive evaluation of the ecological health of the Lake Wesserunsett ecosystem. CEAT examined several factors related to lake water quality, including land use within the watershed, the impacts of residential and commercial development, and physical and chemical measurements of the lake itself. Lake water quality was the primary focus of the study due to its predictive value regarding overall watershed function and viability. The accumulation of nutrients in a lake due to surface runoff and erosion …

Land Use Patterns In Relation To Lake Water Quality In The Messalonskee Lake Watershed, Problems In Environmental Science Course (Biology 493), Colby College, Colby Environmental Assessment Team, Colby College

Colby College Watershed Study: Other Area Studies

The main purpose of this study is to assess the current land use patterns and their influences on the water quality of Messalonskee Lake, including the biotic and abiotic parameters which are involved. More specifically, four main objectives were proposed. First, was to calculate the water budget and flushing rate for Messalonskee Lake. Second, was to determine the influence of current and historical land use patterns on lake water quality. Third, was to utilize gathered information to construct a phosphorus model, which will enable future water quality predictions to be made. Our fourth and final objective was to make recommendations …

Colby College Watershed Study: Other Area Studies

In May of 1990, Tilcon-Maine, Inc. submitted an application to mine gravel on the east side of Horse Point Road on Horse Point in the Town of Belgrade. The project site covers 46 acres and the proposed excavation covers 16 acres. An estimated 740,000 cubic yards of material will be removed over a period of six or seven years (Pfister, pers. comm.). According to Tilcon (Timson et al., 1990) the maximum depth of the pit will be 78 feet and the bottom of the pit will be a minimum of 6 feet above the water table. At the present time …
