Lake Seymour, Vermont, USA

Lake Locations:

USA - New England - Vermont - Northeast Kingdom -

Also known as:  Seymour Lake

Breathtaking autumns and vibrant springs await visitors and residents of Lake Seymour, also known as Seymour Lake. Located in Vermont’s Northeast Kingdom, with 1,769 surface acres of water, Lake Seymour is the second largest lake entirely within the borders of Vermont. Seymour Lake is nestled in Orleans County in the town of Morgan, original home to the beautiful Morgan Horses. The Town of Morgan was chartered in 1780 by the Republic of Vermont to 64 Grantees under the name Caldersburgh. In 1801, it was changed to Morgan in honor of John Morgan who was one of the original owners of the land. When the Town of Morgan was surveyed by General Whitelaw, he gave Seymour Lake its name after Israel Seymour, one of Morgan’s grantees. A dam was built on the natural lake in 1928 to provide hydroelectric power, and is owned by Citizens Utilities Company. Lake Seymour is fed by two streams, outflows of Mud Pond and Sucker Brook. It drains into Echo Pond, which then empties into the Clyde River.

Recreational activities are abundant any time of the year at Lake Seymour, making it a residential paradise as well as a premier vacation destination. Visitors and residents can take a dip in the cool refreshing waters in the summer months or experience the thrill of snowmobiling in the winter. Spectacular fall colors encircle Seymour Lake in the autumn and can be viewed in comfort while sitting on lakeside decks. When the sap is flowing in the spring, residents and visitors can satisfy their palate with the taste of fresh maple syrup. Real estate is abundant along the shores of Seymour Lake, and homeowners are encouraged to be members of Seymour Lake Association, which was founded in 1945 for the purpose of protecting the shoreline and natural resources. Vacation rentals, inns and private campgrounds bordering Lake Seymour offer a charming retreat for those who need a weekend getaway or a longer stay away from the hustle and bustle of everyday life.

Lake Seymour is well known among anglers to be an excellent fishing hole. In 2002, Seymour Lake held the record for the largest lake trout caught in the state of Vermont. In addition to lake trout, the lake is also well known for brook trout and brown trout. Seymour Lake is sometimes called Namagonic, which is a Native American word for “salmon trout spearing place”. This may be due to the fact that landlocked salmon make their homes in the waters of Seymour Lake. Winter in Vermont can be very cold, which causes the lake to freeze enough to support ice fishing in the winter months. Lake Seymour connects to nearby Echo Lake by an out-flowing stream; Echo Lake provides additional fishing spots for anglers. Due to the size of Seymour Lake, boating is another favorite pastime, and with prevailing westerly winds it is also the perfect lake for sailing and windsurfing.

Lake Seymour is nestled in Vermont’s beautiful Northeast Kingdom. This region is well known for its wildlife. With an abundance of moose, deer, and beaver, hunters will find this part of Vermont a fantastic place to hunt. In addition to the extraordinary beauty of the Northeast Kingdom, visitors may enjoy a trip to nearby museums, ski resorts and bike trails. Shopping and additional overnight accommodations can be found in Morgan, Derby, Island Pond and Newport. Other nearby attractions include a Morgan Horse Farm and maple syrup factory.

Vermont was the 14th state added to the union, and with a history dated that far back it is not a surprise to find some enchanting old homes and buildings on the shores of Lake Seymour. Some of the old farm houses date back to the early 1800s. Residents and visitors can take pleasure in the remarkable beauty surrounding Seymour Lake as they sit on lakeside decks watching solitary loons glide across the cool refreshing waters. Peace and tranquility are close at hand to those who vacation or reside at Seymour Lake.

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.

Lake-Area Population | LakeLubbers

This is the estimated number of people who live in a house with a view of a lake, plus those who self-describe the lake as their home, for example: "I live at Smith Mountain Lake."

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.
