Colby College Watershed Study: Great Pond (2012, 2010, 1998)
Eutrophication as a result of human activity is a threat to lake water quality globally and within the state of Maine. Great Pond, in the Belgrade Lakes region of Maine, has traditionally been an oligotrophic lake that is experiencing early signs of eutrophication and is currently classified as a mesotrophic lake. In the fall of 2012, the Colby Environmental Assessment Team (CEAT) measured the primary sources of nutrient loading to Great Pond including the catchment and the lake sediment, current water quality in Great Pond, and the potential impact of the variable milfoil invasion on the lake’s water quality. An …

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
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
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 …

Colby College Watershed Study: Long Pond, South (2007, 1995)
The water quality of the South Basin of Long Pond, located in the Belgrade Lakes region of Maine, was investigated by the Colby Environmental Assessment Team (CEAT) from May to September of 2007. The physical, chemical, and biological characteristics of water quality were analyzed to evaluate the current health of the lake. The Long Pond South watershed was examined to investigate the effect of land-use patterns, including residential and commercial development, on the lake water quality. Data were also collected from road and shoreline surveys to produce maps highlighting areas that could potentially contribute to the degradation of water quality. …

Analysis Of Optimum Location, Viability, And Potential Effects Of Wind Farm Construction In Maine, Elizabeth Benson, Ryan Scott
Analysis Of Optimum Location, Viability, And Potential Effects Of Wind Farm Construction In Maine, Elizabeth Benson, Ryan Scott
Undergraduate Research Symposium (UGRS)
Maine has the highest potential for wind energy in New England and falls within the top twenty states in the nation. It falls just behind Wisconsin and California with an estimate electrical output of 56 billion kWhs. The geological makeup of Maine’s mountains in the western part of the state, and the exposed coastline provide opportune areas to capture wind and convert it into energy. The information included in this poster will suggest the most likely areas for wind development based on a number of factors as recommended by the American Wind Energy Association.

Colby College Watershed Study: Long Pond, North (2006, 1994)
The Colby Environmental Assessment Team (CEAT) investigated the water quality of Long Pond North, located in the Belgrade Lakes region of Maine, from June through December 006. CEAT analyzed several physical, chemical, and biological water quality parameters to determine the current health of the lake. Attributes of the watershed such as land-use patterns and residential and commercial development were also studied to determine their impact on water quality. Data collected were used to produce models of the watershed that enabled CEAT to identify possible sources of degradation to the current and future water quality of Long Pond. To examine historic …
The Isolation And Characterization Of Multiply Antibiotic Resistant Strains Of Fish Pathogenic Flavobacterium Species, Sarah E. Clark, Jaehee Yun, Justin Guay
The Isolation And Characterization Of Multiply Antibiotic Resistant Strains Of Fish Pathogenic Flavobacterium Species, Sarah E. Clark, Jaehee Yun, Justin Guay
Undergraduate Research Symposium (UGRS)
Since the development of the first antibiotics in the 1940’s, there has been widespread overuse in both clinical and agricultural applications. Antibiotic resistance has become a significant problem as a result of subsequent dissemination of antibiotics into the environment, and multiply-resistant strains of bacteria are now a major pathogenic threat. In this study eight separate strains of Flavobacterium responsible for recent disease outbreaks in fish hatcheries throughout Maine were collected and analyzed. All eight strains were found to be resistant to high levels of a number of different antibiotics, including those used for aquaculture as well as human chemotherapeutic applications. …
The Economic Effects Of Ski Resorts On Communities In The State Of Maine, Rachel Freierman
The Economic Effects Of Ski Resorts On Communities In The State Of Maine, Rachel Freierman
Undergraduate Research Symposium (UGRS)
Skiing and snowboarding is a fairly expensive activity for participant and one in which the industry as a whole makes handsome profits. In the 2005/06 season, resorts in the Northeast reported an average gross revenue of $18.5 million. (NSAA) With the current weather phenomenon of El Nino, however, resorts in New England especially, have been suffering economically. The gross revenue in New England in the ’05/’06 season was down 4% from the previous year, likely due to the fact the total snowfall declined by 16%. (NSAA) Much of this loss in revenue came during the Christmas to New Years vacation …

The Impact Of Land Use Patterns And Watershed Characteristics On China Lake, Kennebec County, Maine, Rachel N. Carr, Caroline A. Polgar, Jakob B. Moe, F. Russell Cole, David H. Firmage, Kirsten L. Ness
Undergraduate Research Symposium (UGRS)
China Lake is located in Kennebec County, Maine. Since 1983 the lake has suffered from yearly algal blooms as a result of the addition of excess nutrients. The nutrient load was amplified by erosion within the watershed. Erosion varies widely depending on a number of factors, including the slope of the land, the type of soil, and the way the land is being used. Certain land use types have a high potential to add nutrients to the environment, while others may help absorb excess nutrients and prevent erosion and runoff into the lake. A comprehensive examination of the China Lake …

Colby College Watershed Study: China Lake (2005, 1989)
The Colby Environmental Assessment Team (CEAT) investigated the water quality of China Lake, located in China and Vassalboro Maine, from June through December 2005. The group analyzed physical, chemical, and biological water quality parameters from samples taken on China Lake and from tributaries flowing into the lake. An analysis of land use patterns, especially the impact of residential, commercial, municipal, and institutional development in this watershed, enabled CEAT to study their impact on water quality trends. Data collected by CEAT in 2005 were compared to historic data from the Maine Department of Environmental Protection (MDEP) to gain a historical perspective …
