LAKES from 3 Newfound Lake, the deepest lake in New Hampshire, along with most lakes in the state,
was formed by glacial activity
the glaciers finally began to melt and recede to the north, they left behind huge basins and piles of rocks and boulders strewn across the landscape. Over time, the basins filled up with water, forming many of the lakes we now know in New Hampshire. Lake Winnipesaukee, formed by glacial activity, and with a surface area of approximately 72 square miles, maximum length of 21 miles, and width of up to nine miles, is the state’s largest lake. Newfound Lake in Bris- tol, also formed by glacial activity, with a maximum depth of 183 feet is the deepest lake in the state. Receding glaciers also left behind blocks of ice buried under sand and gravel. As the remnant ice melted, the sand and gravel caved in leaving behind relatively circular basins that eventually filled with water—these types of lakes, referred to as “kettle ponds,” include: Chocorua Lake in Tam- worth; Pea Porridge Pond in Madison and Conway; and Mirror Lake—one of the most highly stud- ied kettle ponds in the world—in the Hubbard Brook Experimental For- est in the White Mountain National Forest near Tam- worth.
Some of New Hamp-
shi re’ s lakes were formed by rivers. As a river winds its way across the landscape, the water going around the outside edge of a bend in the river has the most speed and power—this power leads to the wearing away (ero- sion) of the outer bank of the river, which allows the river to meander further and further out into that eroded bank and the sur- rounding landscape. The eroded materials (dirt, sand, gravel, and rocks) are carried by the fast- flowing water and deposit- ed and accumulate where the river has less energy, typically the inner portion of a river bend. Eventu- ally, the course of the river may change, seeking a straighter path of less resistance. The outside areas of the meanders may then be cut off from the main river channel forming an “oxbow lake.” Oxbow lakes are typically shaped like a “U” or “C” and are not very deep or old. In New Hampshire, Horseshoe Pond in Con- cord is an example of an oxbow lake formed by the meandering of the Mer- rimack River.
Lakes are formed by
the movement of the earth’s crust. The outer
portion of the earth’s crust is made up of approxi- mately a dozen or so slabs of thick rock (tectonic plates) that fit together like a jigsaw puzzle. Forc- es from deep within the earth cause these plates to move and sometimes collide, creating moun- tains and basins. These basins may eventually fill up with water, creating “tectonic lakes.” Notable
