Lake Memphremagog (French: Lac Memphrémagog) is a fresh water glacial lake located between Newport, Vermont, United States and Magog, Quebec, Canada. The lake spans both Quebec and Vermont, but is mostly in Quebec. Most of the watershed that feeds the lake is located in Vermont, and is a source for accumulated phosphorus, sediments and other pollutants. Recent clean up efforts have started to improve the water quality. The lake furnishes potable (drinking) water for 200,000 people.

The lake is 31 miles (50 km) long with 73 percent of the lake's surface area in Quebec, where it drains into the Magog River. However, three-quarters of its watershed, 489 square miles (1,270 km2), is in Vermont. The total is 687 square miles (1,780 km2), with 198 square miles (510 km2) located in Quebec. In Vermont, the lake lies in parts of the towns of Derby and Newport, in addition to the City of Newport, all in Orleans County. In Quebec, the lake lies in parts of Austin, Magog, Ogden, Potton, Saint-Benoît-du-Lac, and Stanstead Township, all in Memphrémagog Regional County Municipality. The lake occupies most of what the Vermont Agency of Natural Resources calls "Basin 17." At the very south end of the lake, there is a South Bay, connected by the narrowest part of the lake.
The lake elevation is 682 feet (208 m). Both ends of the lake are fairly shallow, with depth ranges of 20 feet (6.1 m) to 30 feet (9.1 m). The lake bottom takes a dramatic drop in Canada, starting opposite Mount Owl's Head and continuing that way north to Gibraltar Point, where it starts to climb back to the shallows of the north end. Its maximum recorded depth of 351 feet (107 m) is located in Canada, opposite Jewett Point (at approximately 45.111621, -72.278491). The lake is the third deepest in Vermont. It contains 20 islands. Province Island, the largest, is divided by the international border. The lake is irregular in shape, and along its shores are several striking indentations, in some places low, and in some other parts high and rocky. Along the western shore of the lake are several mountains, prominent among which are Owl's Head, Elephantis, and the Hog's Back.
The Quebec Magog River drains the lake towards the northeast.
Like many other lakes, Memphremagog is accumulating phosphorus, sediments, and other pollutants, primarily runoff from farms, but from other sources as well. In addition, exotic species infestations are a concern, with an existing Eurasian water milfoil population and the potential for a zebra mussel infestation. Since the 1970s, significant efforts have been made to reduce the polluting effects of direct discharges into the lake and its tributaries, and lake quality has improved.
In 1994, a Lake Memphremagog Watershed Association was formed to focus on solving lake and river issues. Testing done in 2008 was unable to determine the cause of excessive nitrogen and phosphorus. In 2010, a study revealed that farms contribute disproportionately to nutrient loads. Although farms have 16% of total land use in the drainage area, they produce 44% of the runoff. Baseline nutrients for a lake are 14 micrograms of phosphorus per litre of water. The lake was measured at 17 micrograms, 18% above the standard. Although the acreage devoted to farming has decreased, the retired land has most often been developed, itself a source of runoff.
Origin of name
- Memphremagog comes from the word "Memrahabegek", which means "where there is a big expanse of water".
- Memphremagog was also pronounced as "Mamphremagog". This came from the Abenakis "Mamlawbagak" which signifies "a long and large sheet of water". The prefix "mamlaw" denotes largeness or abundance; the particule "baga" denotes water; and "k" marks the name as given in local term.
The first accurate depiction of the map was in 1776. This marks the beginning of interest by settlers.
The Mountain Maid paddlewheeler operated from 1850 to 1870. The Lady of the Lake steam excursion/ferry paddlewheeler started operating in 1867. It stopped operations in 1917. It was based in Newport. The Anthemis steamer was built in 1909 to carry 300 people. It stopped operating after 1945.
Lake Memphremagog allegedly contains a cryptid named Memphre (or Memphré), which has received sightings since the 18th century and continues on in the folklore of the area. A sighting of Memphre was reported in 2000.
Lake Memphremagog is known to have had at least three lighthouses on the Vermont side and seven on the Quebec side. These were used in aiding boaters in navigating the waters of the large lake.
All three of the original lighthouses have been demolished.
Maxfield Point Light
The Maxfield Point Light was a small lighthouse constructed on the Vermont side of Lake Memphremagog in 1879. A conical, cast iron structure, it was 25 feet (7.6 m) tall, with a focal plane 40 feet (12.2 m) above sea level. It showed a fixed white light, visible for 10 (16 km) miles. The lighthouse no longer exists; it is unknown what happened to it, or when it was deactivated.
Newport Wharf Light
The Newport Wharf Light was a tower that was built in the Newport section of Lake Memphremagog in 1879. The lighthouse was a steel skeleton tower, painted red, that was fixed on a concrete foundation. The tower showed a fixed red light that was visible for up to 12 mi (19 km), with the height of the focal plane being 37 feet (11.2 m). As with the Maxfield Point Lighthouse, the date this lighthouse was demolished is unknown.
Whipple Point Light
Whipple Point Light was a tower that was built on the end of a pier on Whipple Point in Lake Memphremagog. Built in 1879, the tower was constructed of wood in a hexagonal shape and stood 13 feet (4 m). The light was fixed white and was visible from up to 10 mi (16 km) away, with a focal plane of 25 feet (7.6 m). The lighthouse was deactivated around 1906 and was demolished at an unknown date.
Most of the Quebec lighthouses were originally established in 1878. None of the original lighthouses have survived, although some of them have been replaced by simple navigation lights. From north to south, the lighthouses were:
Magog Lighthouse was located on a freight shed and had a fixed red light with a range of 8 miles (13 km). It was built in 1910 and located near Magog. It was demolished on an unknown date.
Witch Shoal Lighthouse
Witch Shoal Lighthouse was located about 0.5 miles (0.80 km) southwest of Magog. The original lighthouse was built in 1878 as a 21 feet (6.4 m) white square wooden tower on a pier. It had a fixed white dioptric light located at a height of 19 feet (5.8 m) above the high water mark and with a range of 9 miles (14 km). It was rebuilt in 1900. In April 1933, it was destroyed by pressure from the ice caused by the rising level of the lake. It was rebuilt in 1960 as a small metal tower, which was swept away by spring ice in 1978. Since 1980, the mast that replaced it is left in place only from May to October each year. The tower is 23 feet (7.0 m) high with a fixed white light that has a range of 9 miles (14 km) and a focal plane of 28 feet (8.5 m). The aid is owned by the Coast Guard and maintained by a private contractor.
Black Point Lighthouse
Black Point Lighthouse was located on the western side of the lake, about 3 miles (4.8 km) southwest from Witch Shoal lighthouse. It was also known as the Green Point Lighthouse. It was built in 1878 as a 22-foot (6.7 m) white square wooden tower. It had a fixed white catoptric light located at a height of 24 feet (7.3 m) above the high water mark and with a range of 8 miles (13 km). It had a focal plane of 22 feet (6.7 m). It was rebuilt in 1914 and demolished on an unknown date.
Wadleigh's Point Lighthouse
Wadleigh's Point Lighthouse was located on the western side of the lake, about 4 miles (6.4 km) southwest of Black Point lighthouse. It was also known as the Bryant Landing Light and was near Austin. The original lighthouse was built in 1878 as a 22-foot white square wooden tower with a fixed white catoptric light located at a height of 30 feet (9.1 m) above the high water mark and with a range of 8 miles (13 km). In approximately 1914, that was replaced by a square pyramidal skeletal tower with enclosed lantern. In 1939, that was replaced by a 18 feet (5.5 m) square skeletal tower with enclosed lantern. In 1980, that was replaced by a modern 22 feet (6.7 m) steel tower with a fixed white light that has a range of 8 miles (13 km). The still-active light is installed from May to October each year.
Chateau de Silva Lighthouse
Chateau de Silva Lighthouse was located on the western side of the lake at the Revere House (formerly the Chateau de Silva) hotel wharf, approximately 5 miles (8.0 km) southwest of the Wadleigh's Point lighthouse. It was built in 1878 as a 22 feet (6.7 m) white square wooden tower with a fixed white catoptric light located at a height of 20 feet (6.1 m) above the high water mark and with a range of 8 miles (13 km). The light had a focal plane of 20 feet (6.1 m). It was demolished on an unknown date.
Molson's Island Lighthouse
Molson's Island Lighthouse was located on the southwest point of Molson's Island, approximately 2 miles (3.2 km) southeast of the Chateau de Silva lighthouse. This was on the eastern side of the lake, near Georgeville. It was built in 1878 as a 22 feet (6.7 m) white square wooden tower with a fixed white catoptric light located at a height of 28 feet (8.5 m) above the high water mark and with a range of 8 miles (13 km). The light had a focal plane of 28 feet (8.5 m). It was rebuilt in 1914 and demolished on an unknown date. The light was replaced with a lighted buoy.
Lead Mines Lighthouse
Lead Mines Lighthouse was located on the western side of the lake, approximately 4 miles (6.4 km) southwest of the Molson's Island lighthouse. This was near Leadville, at the foot of Mount Owl's Head. It was built in 1878 as a 22 feet (6.7 m) white square wooden tower with a fixed white catoptric light located at a height of 20 feet above the high water mark and with a range of 8 miles (13 km). The light had a focal plane of 22 feet (6.7 m). It was rebuilt in 1914 and demolished on an unknown date.
The watershed in Vermont is largely agricultural and forest land with residential development increasing in recent years in both Vermont and Quebec.
The lake furnishes potable (drinking) water for 200,000 people.
In 2011 a day cruise ship started summer operations on the Canadian side of the lake.
Sargent's Bay Yacht Club
Sargent's Bay Yacht Club, despite it's name, is a small children's dinghy sailing club based out of Sargent's Bay. It operates throughout 8 weeks of the summer, hosting up to 40 campers a week, with a staff of 5-7 depending on the summer. It was started in 1935 by several families in the bay, with the goal of teaching their children the basics of the sport they all cherished so much, sailing. Since 1935, the Fisher family has graciously allowed the operation of the club to continue on their property. You can visit their website at (www.sargentsbayyachtclub.com).
Lake Memphremagog is mentioned in a novel by Chris Bohjalian, Close Your Eyes, Hold Hands. In the novel, the lake is the site of a nuclear reactor that has suffered a cataclysmic meltdown.
Lake Memphremagog is mentioned in Northwest Passage, a historical novel by Kenneth Roberts about the 1759 Rogers' Rangers raid. In Northwest Passage (1940), the film based on the novel, Spencer Tracy uses a map that shows Lake Memphremagog and the environs.
The Canadian band The Tragically Hip mentions Lake Memphremagog in their 2002 unreleased song Problem Bears; part of their In Violet Light album sessions.
