Pollution: First, the phosphorus-rich discharge would promote the growth of plant life, intensifying existing algal blooms and weed infestations. Second, the heat that would be released into the lake by the warmed water discharge could allow algae and aquatic weeds to grow for longer or different periods and could otherwise upset the sensitive ecological balance of plant and animal species in the lake. Third, the large-scale construction activities associated with the project would release silt into the lake and increase existing turbidity problems. Numerous toxic sites pose known or potential threats to the lake, including former utility sites, leaking petroleum tanks and abandoned landfills. 1. Describe the attributes of the Lake Cayuga ecosystem (biotic & abiotic subcomponents; matter and energy exchanges between components; interaction & interdependencies; autogentic, allogenic & biogenic processes; etc.) Lake Cayuga is New York’s second largest finger lake, with an area of 42,956 acres and length of 40 miles long. Lake Cayuga’s max depth of 435 feet and volume of 2.5 trillion gallons creates a very unique ecosystem for many biotic and abiotic organisms. Up state New York has very dramatic seasons where the weather and temperature changes dramatically throughout the year. Deep lakes contain three distinct zones, each with different types of organisms. The Littoral Zone is the areas closest to the shore where light reaches all the way to the bottom. With available sunlight plants and algae are able to survive. The temperatures of the shallow areas of the lake fluctuate with the seasons
