When visitors and residents think of the lakes of New Hampshire, they envision clear blue waters surrounded by dense, green forests. These two qualities are inextricably tied in our minds but many do not realize their interdependent relationship. There are many threats facing New Hampshire s surface waters. Its lakes, rivers and wetlands face pressures from increased development which can lead to accelerated eutrophication, erosion and loss of vital habitat for wildlife and people alike.
Eutrophication is the natural aging process of lakes.
When this vegetation dies, its decomposition creates more nutrients. Accelerated eutrophication is the result of cultural influences, such as development, that prematurely age a lake. Erosion is the loss of soils due to wind, ice and wave action, as well as runoff from rain and spring snow melt. Removal of vegetation and its root systems causes soil and pollutants to be washed into a lake or river and reduces water clarity. Natural, healthy shorelands are green places that meet clean, blue waters.
