Lake Kanasatka, New Hampshire, USA

Lake Locations:

USA - New England - New Hampshire - Lakes Region -

Also known as:  Long Pond

Lake Kanasatka is a clear, 371-acre freshwater lake set among New Hampshire’s towering trees and surrounded by sloping hillsides. The lake was once named Red Hill Pond for the hill beyond its northern shoreline. Lake Kanasatka is used mostly for recreational purposes throughout the year. A day on the lake will reveal anything from anglers out in the early morning to children swimming in the summer or ice skating in the winter.

Old maps dating back to the 1800s also refer to Lake Kanasatka as Long Pond due to its long, narrow shape, about two miles long and .3 miles wide. The lake was once used to float logs to the old sawmill, which is currently the location of a bait shop. Inflow comes from a variety of sources, including Wakondah Pond, which lies to the west, snow melt from surrounding hillsides, and underground springs. A dam, which was built in 1954 and is now owned by the New Hampshire Water Division, regulates the lake’s water levels. The lake averages 18 feet deep with a maximum depth of 40 feet. Water that flows out from the dam follows a stream which eventually empties into Lake Winnipesaukee, New Hampshire’s largest lake at 44,586 acres.

The heavily-wooded shoreline at Lake Kanasatka makes for a perfectly peaceful getaway, and visitors find a plentiful number of lakeside vacation rentals and real estate opportunities here. Take your pick of lake activities, which range depending on when you visit. Fall and spring are both good times for exploring and hiking along trails nearby, while summer simply demands most of your time to be spent on or in the lake. Wakeboarders and water skiers can be seen racing atop the shimmering surface, while kayakers and canoeists paddle leisurely along the shoreline. Bundle up during the winter for ice skating and ice fishing atop this wonderland.

Anglers find Lake Kanasatka to be a promising spot for reeling in catches of smallmouth bass, largemouth bass, chain pickerel, white perch, yellow perch, sunfish and brown bullhead. A public boat launch allows everything to enter the lake except skicrafts, such as jet skis. Be mindful of loons nesting in various spots around the lake.

The Town of Moultonborough resides less than five miles to the northeast of Lake Kanasatka, where families happily call the area home. If you’re just visiting, check out any summertime music festivals downtown, or drop into a cafe while exploring unique shops scattered throughout the town. For a bit more escapism, check out the Castle in the Clouds, a castle built atop a nearby mountain in the early 1900s. Learn of its history, born of a millionaire shoemaker, and tour the grounds, which are open May through October.

For more of an outdoor adventure, the southern section of the White Mountain National Forest is only 20 miles from the shores of Lake Kanasatka. At 800,000 acres, visitors come for backcountry skiing, hiking, camping or scaling Mount Washington, the highest point to the north of the Smoky Mountains. Wildlife abounds in this forest, with sightings of bear, moose and the reintroduced peregrine falcon.

It is all within a short reach of Lake Kanasatka. Whether you’re wishing to grill out during the summer or snowshoe around the lake in the winter, Lake Kanasatka offers a fulfilling spot to find a bit of peacefulness.

Trophic State | LakeLubbers

Trophic State measures the level of algae and nutrients in a lake.

An oligotrophic lake is very clear (blue in color) and does not support much plant or fish life. A hyper-oligotrophic lake is the clearest of all lakes, and is nearly devoid of plants and fish.

A mesotrophic lake is slightly green and supports a moderate degree of plant and fish life. A lake's most desired trophic state is generally this mid-point - the mesotrophic state.

A eutrophic lake is somewhat murky and supports a large amount of plant and fish life. A hypereutrophic lake is clouded with algae, plant life, and fish life. A eutrophic or hyper-eutrophic lake can be difficult to navigate by boat - and is often an unpleasant place to swim.

The use of phosphorus-rich and nitrogen-rich fertilizer on lawns and golf courses surrounding a lake can cause it to become eutrophic or hypereutrophic.

Catchment or Drainage Area | LakeLubbers

This is the surrounding area that drains into a lake, including land, rivers and their tributaries. This is also known as the lake's "catchment basin".

Small lakes at the highest peaks of mountains have small drainage areas. The world's oceans have the largest drainage areas.

Water Residence Time | LakeLubbers

This is the estimated time that it takes for an amount of water equal to the entire volume of a lake to flow out of - or evaporate from - the lake.

Residence Time can be as short as a few days for fast-flowing small lakes, and can exceed 100 years for slow-flowing large lakes.

Completion Year | LakeLubbers

This is the year that a reservoir was first filled to the reservoir's normal elevation - or the year that a natural lake was first dammed. A large reservoir can take more than a year to fill after its dam is first closed.

The Grand Anicut in southern India is generally considered the world's oldest dam that still operates. Grand Anicut was constructed in the second century BC. It now impounds an irrigation network that includes roughly one million acres.

Water Volume | LakeLubbers

This is the estimated volume of water that a lake contains -- measured at the lake's normal elevation. By this measure, the world's largest freshwater lake is Siberia's Lake Baikal.

You can find many of the the world's largest lakes (by water volume) on LakeLubbers.

Water Volume can be measured in acre-feet, in cubic miles, or in cubic kilometers. One acre-foot is the amount of water needed to cover one acre (43,560 square feet) to a depth of one foot. One cubic mile equals 3,379,200 acre-feet. One cubic kilometer equals 810,713 acre-feet.

1 acre-foot is equal to 325,851 US gallons. Siberia's Lake Baikal contains about 6,276,367,740,000,000 gallons of freshwater - nearly 1 million gallons for every living person on earth.

The other - and more widely used - measure of a lake's size is the lake's surface acreage. By that measure, the world's largest freshwater lake is North America's Lake Superior.

Average Depth | LakeLubbers

This is the estimated average depth of the water in a lake -- measured at the lake's normal elevation. If the water volume and surface area of a lake are known, an estimate of the lake's average depth can be calculated:

Water volume ÷ Surface Area = Average Depth

Example: 1,000,000 acre-feet ÷ 20,000 acres = 50 feet average depth

Maximum Elevation | LakeLubbers

This is a lake's highest water level, measured by the lake's surface distance above sea level, that can occur during flooding. A lake's highest possible maximum elevation is usually the top of the lake's dam or spillway.

At lakes that include residential development, government regulations usually forbid the construction of homes below a lake's maximum elevation.

Minimum Elevation | LakeLubbers

This is a lake's lowest water level, measured by the lake's surface distance above sea level, that can be reasonably expected to occur. Low lake levels can occur due to deliberate seasonal draw downs for irrigation or impending snow melt, reduced water inflows, drought and evaporation, residential or commercial water demands, and hydropower generation.

Some lakes' minimum and maximum elevations are virtually the same. Lakes that generate hydropower may vary by several feet - according to power demand. Lakes whose primary purpose is to prevent flooding can seasonally vary by 100 feet or more.

When some lakes reach their minimum elevation, their boat ramps may not be long enough to permit boat access - and boats docked on shallow parts of the lake may end up on dry ground. In those cases, kayakers and shore-based anglers may be among the few happy recreational users of the lake.

Normal Elevation | LakeLubbers

This is a lake's normal water level, measured by the lake's surface distance above sea level. For a reservoir, this water level is also known as "full pond" or "full pool".

You can find many of the world's highest-elevated lakes on LakeLubbers. Lakes with the lowest elevations (known by LakeLubbers) are shown on the final page of that list.

Shoreline Length | LakeLubbers

This is the length of the exterior shoreline around a lake - measured at the lake's normal elevation. The shoreline length can be considerably shorter or longer when lake water levels are lower or higher than normal.

A lake with many coves has a much longer shoreline than a lake of similar surface area that is nearly circular in shape.

When known, the shoreline miles that we report in our statistics include only the lake's exterior shoreline, and exclude the shorelines of islands located within a lake's boundaries. In lakes with many islands, those islands' combined shorelines may exceed a lake's exterior shoreline.

You can find many of the world's longest-shoreline lakes on Lakelubbers.

Surface Area | LakeLubbers

This is the area (acreage, square kilometers, etc.) of the top surface area of a lake - measured at a lake's normal elevation. The surface area can be considerably smaller or larger when lake levels are lower or higher than normal. North America's Lake Superior is the world's largest freshwater lake by this measure.

The other measure of a lake's size is the lake's water volume. By that measure, the world's largest freshwater lake is Lake Baikal in Siberia.

You can find many of the world's largest lakes (acres) on Lakelubbers. There is no widely-accepted minimum surface area that defines a lake. What Lakelubbers describes as a lake, you might call a pond. The smallest lake that Lakelubbers currently includes is Hawaii's 2-acre Lake Waiau.

Water Level Control | LakeLubbers

This is the organization that controls water releases or outflows from the lake or reservoir. In the USA, this is often the US Army Corps of Engineers, a power company, a municipal water system, an irrigation district, or a paper manufacturing company. In the case of private or gated lakes, a homeowners' association may be the lake's controlling authority.

Many lakes cross borders, including North America's Great Lakes. The control of such lakes and their coveted freshwater may be amicably shared - or hotly disputed.

"Water wars" continue at many lakes as growing populations and crop irrigation needs compete for the freshwater that lakes contain.

Lake Type | LakeLubbers

There are 3 basic types of lakes that are currently included on LakeLubbers. 2 types may be dammed or not dammed, producing 5 classifications.

- A Reservoir is a man-made freshwater lake that is usually created by damming rivers.

- A Natural Freshwater Lake occurs naturally - often by glacial activity - and has a salinity of less than 30 parts per thousand. It may be dammed to produce electricity or for other reasons.

- A Natural Saltwater Lake occurs naturally and has a salinity of more than 30 parts per thousand (ppt). It may be dammed.

"Brackish" water may be categorized as freshwater or saltwater, depending on its salt content (salinity). Oligohaline water has less than 15 ppt of salt. Mesohaline water has 15-29 ppt. Polyhaline has 30-335 ppt.
