Oligo Trophic Lake Homes
I get asked all the time about finding a lake home on crystal clear water. an The waters of such lakes are of high-drinking quality and therefore considered the "cleanest" by many. They are actually "young lakes" and are classified as ‘oligotrophic,’ These kinds of lakes typically contain low concentrations of nutrients (such as phosphorus), are steep-sided, have clear water, have sand or rock along most of the shoreline, contain few aquatic plants, support little algal growth, and support cold water fisheries.
Fifteen thousand years ago, the natural lakes and ponds of New Hampshire were created by the retreat of glaciers. Ever since then they have been going through a natural process of filling-in So all of the lakes are approximately the same age, however are filling in with sediment at different rates. Lakes are said to be ‘young’ if they are filling in very slowly and their characteristics have not changed much since the lake was formed.
It does not mean other lakes like a mesotrophic lake is any less clean--just not as clear and will support vegetation and places for fish it hide and breed. The tea color you see so often in lakes is from the natural high levels of iron found everywhere in New Hampshire--afterall we are the Granite State
The top two clearest lakes in NH are Merrymeeting and Newfound lake. Other Oligotrophic lakes in New Hampshire include.
