Erosion

Unfortunately, there are many threats to Bear Pond. Among the threats are acid rain, dam failure, mercury contamination, and surface use conflicts. However, the most imminent threats are algae blooms and invasive species.

Algae blooms that result from phosphorus pollution. Phosphorus is naturally found in soil, but is also present in high concentrations in fertilizer, oil, soaps, and septic effluent. As the watershed is developed with homes, driveways and other hard surfaces, the amount of rainwater runoff into the lake increases. This runoff carries large amounts of phosphorus into the lake, which can trigger algae to grow out of control, resulting in an algae bloom.

Lakes are very fragile environments that are susceptible to algae blooms resulting from phosphorus pollution from erosion and rainwater run-off. Algae are normally found in lakes, but at low levels. They are held in check by a lack of key nutrients such as phosphorus. When phosphorus is flushed into the lake, it can trigger algae to grow out of control, resulting in a bloom. This will quickly ruin swimming and recreational activities.

In July 2000, BPIA began working with Oxford County Soil and Water Conservation, and numerous representatives from the Maine DEP to produce and submit a Watershed Survey Report to numerous State Agencies. This Report served as an application for funding to repair problem sites within the Bear Pond Watershed . In early 2002, our application was approved by the Maine DEP.

a_bad_shoreline
This is an example of shoreline development that will lead to rainwater run-off that carries phosphorus into the lake.
a_good_shoreline
This is an example of an environmentally friendly shoreline development that will cause minimal rainwater run-off.   As a general rule, THE WILDER THE BETTER!!
