The five Great Lakes are Lake Superior, Lake Michigan, Lake Huron, Lake Erie, and Lake Ontario. These enormous freshwater lakes lie along the border of the United States and Canada and form one of the most important freshwater systems in North America. They provide drinking water, support wildlife, connect major cities, and create countless opportunities for fishing, boating, swimming, and sightseeing.
If you want to remember the names, learn where each lake is located, or discover which one is the largest, deepest, or shallowest, this guide explains the essential facts. You will also learn how the lakes connect, how they compare in size, and why protecting their water matters.
What Are the Five Great Lakes Called?
The five Great Lakes are:
- Lake Superior
- Lake Michigan
- Lake Huron
- Lake Erie
- Lake Ontario
They are commonly listed from west to east in this order. Together, they contain about 21% of the world’s surface freshwater, making them an extraordinary natural resource.
The lakes are shared by the United States and Canada. Four cross the international border, while Lake Michigan lies entirely within the United States.
What Are the Five Great Lakes in Order?
The following table shows the five lake names in their commonly used west-to-east order, along with a key fact about each one.
| Order | Great Lake | Key fact |
| 1 | Lake Superior | Largest by surface area and volume |
| 2 | Lake Michigan | Only Great Lake entirely within the United States |
| 3 | Lake Huron | Has an extensive shoreline and many islands |
| 4 | Lake Erie | Shallowest by average depth |
| 5 | Lake Ontario | Connects to the St. Lawrence River |
Although this is the usual west-to-east listing, the lakes form a connected water system rather than a simple straight line. Lake Michigan and Lake Huron are directly connected, and Lake Ontario receives water from Lake Erie through the Niagara River.
How to Remember the Five Great Lakes
One of the easiest ways to memorize the five Great Lakes is the word HOMES. Each letter represents the first letter of a lake’s name.
- H — Huron
- O — Ontario
- M — Michigan
- E — Erie
- S — Superior
The HOMES mnemonic is useful for geography classes, school exams, trivia games, and general knowledge. You do not need to memorize the names in this order; the word simply helps you remember all five.
Another way to learn them is to study a map and follow the lakes from west to east: Superior, Michigan, Huron, Erie, and Ontario.
Where Are the Five Great Lakes Located?
The Great Lakes are located in northeastern North America, along the international border between the United States and Canada. They extend more than 750 miles (1,200 kilometers) from west to east. Their surrounding region includes major cities, forests, beaches, islands, wetlands, and industrial centers.
The eight U.S. states bordering at least one Great Lake are:
- Minnesota
- Wisconsin
- Illinois
- Indiana
- Michigan
- Ohio
- Pennsylvania
- New York
The Canadian province of Ontario also borders all five lakes. Lake Michigan is the only lake entirely within the United States, while the other four share shores with Canada.
Here is where each lake sits in the region:
- Lake Superior: The northwesternmost Great Lake, bordering Minnesota, Wisconsin, Michigan, and Ontario.
- Lake Michigan: Located west of Michigan’s Lower Peninsula, bordering Wisconsin, Illinois, Indiana, and Michigan.
- Lake Huron: Located east of Michigan’s Lower Peninsula, bordering Michigan and Ontario.
- Lake Erie: Situated south of Lake Huron, bordering Michigan, Ohio, Pennsylvania, New York, and Ontario.
- Lake Ontario: The easternmost Great Lake, between New York and Ontario.
Comparison of the Five Great Lakes by Size and Depth
The five Great Lakes differ considerably in surface area, volume, and depth. The following figures are approximate measurements published by the U.S. Environmental Protection Agency and NOAA’s Great Lakes research program.
| Great Lake | Surface area | Average depth | Maximum depth |
| Lake Superior | 31,700 sq. mi. | 483 ft | 1,332 ft |
| Lake Michigan | 22,300 sq. mi. | 279 ft | 925 ft |
| Lake Huron | 23,000 sq. mi. | 195 ft | 750 ft |
| Lake Erie | 9,910 sq. mi. | 62 ft | 210 ft |
| Lake Ontario | 7,340 sq. mi. | 283 ft | 802 ft |
Note: Surface areas are rounded. Depth figures are approximate and measured relative to the low-water reference level used in the published data.
Which Great Lake Is the Largest?
Lake Superior is the largest Great Lake by surface area, covering approximately 31,700 square miles (82,100 square kilometers). It is also the largest by water volume, holding around 2,900 cubic miles of water.
Its enormous size creates a landscape that can resemble an inland sea. Strong winds, large waves, cold water, and long stretches of undeveloped shoreline distinguish it from many smaller lakes.
Which Great Lake Is the Smallest?
Lake Ontario is the smallest of the five Great Lakes by surface area, covering approximately 7,340 square miles (18,960 square kilometers).
However, the smallest surface area does not mean the least depth or the lowest volume. Lake Ontario has an average depth of approximately 283 feet, making it deeper on average than Lake Huron and Lake Erie.
Which Great Lake Is the Deepest?
Lake Superior is the deepest Great Lake by maximum depth, reaching approximately 1,332 feet (406 meters).
Its average depth is about 483 feet, far greater than Lake Erie’s average depth of around 62 feet. The cold, deep waters of Lake Superior also mean that its seasonal water temperatures can differ considerably from those of shallower lakes.
Which Great Lake Is the Shallowest?
Lake Erie is the shallowest Great Lake by both average and maximum depth. Its average depth is approximately 62 feet, and its maximum depth is around 210 feet.
Its relatively shallow water allows it to warm more quickly in summer. The western basin is especially shallow, which also makes it more susceptible to sediment disturbance and certain water-quality problems.
1. Lake Superior
Lake Superior is the largest of the five Great Lakes by surface area and water volume. It borders Minnesota, Wisconsin, and Michigan in the United States, along with Ontario in Canada.
Its shoreline features rocky cliffs, sandy beaches, forests, and picturesque bays. The lake attracts visitors who enjoy hiking, camping, kayaking, fishing, and exploring state and provincial parks.
Lake Superior’s approximate surface area is 31,700 square miles. It has an average depth of 483 feet and a maximum depth of 1,332 feet. These measurements make it the deepest Great Lake at its deepest point.
Its water remains cold for much of the year, and sudden weather changes can create hazardous boating conditions. The lake is also an important habitat for fish and other aquatic species.
What makes Lake Superior special?
- It has the largest surface area of the five Great Lakes.
- It contains more water by volume than any other Great Lake.
- It has the greatest maximum depth.
- It supports commercial shipping, recreation, and wildlife.
- It is known for its cold water and rugged scenery.
Lake Superior’s vast size and natural beauty make it one of the most recognizable geographical features in North America.
2. Lake Michigan
Lake Michigan is the only Great Lake located entirely within the United States. It borders Wisconsin, Illinois, Indiana, and Michigan.
The lake covers approximately 22,300 square miles and has an average depth of 279 feet. Its maximum depth reaches about 925 feet. Although Lake Huron has a slightly larger surface area, Lake Michigan holds more water by volume.
Chicago is one of the major cities along Lake Michigan’s shoreline. Other communities attract visitors with sandy beaches, waterfront parks, marinas, and coastal dunes.
The lake supports recreational and commercial fishing, boating, shipping, and tourism. Its water also serves as an important freshwater resource for surrounding communities.
What makes Lake Michigan special?
- It is the only Great Lake entirely within one country.
- It has extensive sandy beaches and coastal dunes.
- It borders four U.S. states.
- It supports major urban areas, including Chicago.
- It offers numerous opportunities for boating, fishing, and swimming.
Despite its attractive beaches, Lake Michigan can develop powerful waves and dangerous currents. Visitors should follow local swimming advisories and pay attention to weather conditions.
3. Lake Huron
Lake Huron lies between Michigan and Ontario. It has a surface area of approximately 23,000 square miles, making it the second-largest Great Lake by surface area.
Its average depth is about 195 feet, and its maximum depth is approximately 750 feet. Lake Huron is particularly famous for its extensive shoreline, islands, bays, and coastal scenery.
Georgian Bay, located along the northeastern side of Lake Huron, is known for its rocky landscapes and recreational destinations. Manitoulin Island, situated in Lake Huron, is the world’s largest freshwater island.
Lake Huron connects directly to Lake Michigan through the Straits of Mackinac. Because of this connection, the two lakes share essentially the same water level and function as closely linked parts of the Great Lakes system.
What makes Lake Huron special?
- It has the second-largest surface area among the five lakes.
- It contains numerous islands and sheltered bays.
- It includes Georgian Bay and Manitoulin Island.
- It connects directly with Lake Michigan.
- It supports boating, fishing, tourism, and wildlife habitats.
Lake Huron’s diverse shoreline makes it an important destination for people seeking outdoor activities and scenic freshwater landscapes.
4. Lake Erie
Lake Erie is the fourth-largest Great Lake by surface area and the shallowest by average depth. It borders Michigan, Ohio, Pennsylvania, and New York in the United States, along with Ontario in Canada.
The lake covers approximately 9,910 square miles. Its average depth is about 62 feet, while its maximum depth reaches approximately 210 feet.
Because Lake Erie is relatively shallow, its waters warm more quickly during the summer than those of deeper Great Lakes. This supports seasonal recreation and makes the lake an important fishing destination.
Cities such as Cleveland, Ohio, and Buffalo, New York, lie along its shoreline. The lake also supports shipping, tourism, and nearby agricultural communities.
Lake Erie faces water-quality challenges, including excessive nutrients from agricultural runoff and other sources. These nutrients can contribute to harmful algal blooms, which threaten aquatic ecosystems and may affect drinking-water supplies.
What makes Lake Erie special?
- It is the shallowest Great Lake by average depth.
- Its water generally warms faster than that of the deeper lakes.
- It supports valuable recreational and commercial fisheries.
- It provides water for nearby communities.
- It requires ongoing protection from pollution and harmful algal blooms.
Although Lake Erie is smaller and shallower than the other lakes, it plays a major role in the region’s economy and environment.
5. Lake Ontario
Lake Ontario is the smallest Great Lake by surface area. It lies between Ontario, Canada, and New York, United States.
Its surface area is approximately 7,340 square miles, its average depth is about 283 feet, and its maximum depth is approximately 802 feet. This makes Lake Ontario significantly deeper on average than Lake Erie.
The lake receives water from Lake Erie through the Niagara River, which includes Niagara Falls. Water then leaves Lake Ontario through the St. Lawrence River, continuing toward the Atlantic Ocean.
Toronto lies along the northwestern shore of Lake Ontario. The lake also supports shipping, fishing, drinking-water supplies, waterfront recreation, and a variety of aquatic habitats.
What makes Lake Ontario special?
- It is the smallest Great Lake by surface area.
- It is considerably deeper than Lake Erie.
- It receives water from Lake Erie.
- It drains into the St. Lawrence River.
- It borders the major Canadian city of Toronto.
Lake Ontario is an essential part of the Great Lakes water system because it serves as the final Great Lake before water flows into the St. Lawrence River.
How Are the Five Great Lakes Connected?
The five Great Lakes form a connected freshwater system. Water flows through rivers and straits from one lake to another before eventually reaching the Atlantic Ocean.
The general flow of water follows this route:
- Lake Superior: Water flows out through the St. Marys River.
- Lake Michigan and Lake Huron: These two lakes connect through the Straits of Mackinac and share the same water level.
- Lake Huron to Lake Erie: Water passes through the St. Clair River, Lake St. Clair, and the Detroit River.
- Lake Erie to Lake Ontario: Water flows through the Niagara River, including Niagara Falls. The Welland Canal also allows ships to bypass the falls.
- Lake Ontario to the Atlantic Ocean: Water flows through the St. Lawrence River.
Lake St. Clair is an important connecting lake, but it is not one of the five Great Lakes. The same distinction applies to the rivers and channels that link them.
The connected system supports shipping, wildlife movement, recreation, and the movement of freshwater throughout the region.
Which Great Lake Is the Clearest?
There is no single Great Lake that is always the clearest everywhere and under all conditions. Water clarity changes with location, season, weather, algae, suspended sediment, and other environmental factors.
Lake Superior is often associated with exceptionally clear water in many areas, particularly where shorelines are rocky and human disturbance is limited. However, clarity varies within the lake, and clear-looking water does not automatically mean the water is safe to drink or swim in.
Lake Michigan and Lake Huron also have areas with clear water, particularly in some sheltered bays and nearshore locations. Lake Erie can be more turbid in certain areas, especially its shallow western basin, where waves can disturb bottom sediments.
It is important to distinguish water clarity from water quality. Clear water may still contain harmful microorganisms or chemical contaminants, while naturally cloudy water is not necessarily polluted.
For swimming, check local beach advisories rather than judging safety by appearance alone.
Which Great Lake Is the Warmest?
Lake Erie often warms more quickly during summer because it is the shallowest Great Lake by average depth. Its relatively small volume of water compared with the deeper lakes allows seasonal temperatures to rise more rapidly.
However, there is no single lake that is warmest at every location and at every time of year. Temperature depends on the season, weather, wind, water depth, and the specific part of the lake being measured.
Lake Superior generally remains colder than the shallower lakes, particularly during spring and early summer. Its deep water takes longer to warm, and cold conditions can persist even when the air feels warm.
Lake Michigan, Lake Huron, and Lake Ontario experience their own seasonal temperature patterns. Nearshore water can warm faster than deeper offshore water, so local conditions may differ substantially.
If you plan to swim, check current water temperatures, weather conditions, and beach safety notices before entering the water.
Why Are the Five Great Lakes Important?
The Great Lakes are much more than five large bodies of water. They provide freshwater, support ecosystems, connect communities, and contribute to the economies of both the United States and Canada.
1. Freshwater Supply
The Great Lakes provide water for drinking, household use, agriculture, and industry. Their enormous freshwater resources make water protection a priority for communities throughout the region.
2. Transportation and Trade
Ships carry bulk goods and other cargo through the Great Lakes and connecting waterways. The Great Lakes–St. Lawrence Seaway system helps connect inland ports with international shipping routes.
3. Wildlife and Natural Habitats
The lakes support fish, aquatic plants, birds, wetlands, and other wildlife. Coastal habitats also provide important feeding and breeding areas for many species.
4. Tourism and Recreation
Visitors enjoy beaches, parks, fishing, camping, boating, kayaking, and sightseeing around the lakes. These activities support local businesses and tourism-related employment.
5. Local Economies
The Great Lakes region supports shipping, manufacturing, agriculture, commercial fishing, and other industries. Millions of people depend directly or indirectly on the region’s water resources and economic activity.
6. Environmental Protection
Pollution, invasive species, habitat loss, and excessive nutrient runoff can harm the lakes. Cooperation between the United States and Canada helps protect water quality and maintain the health of this shared ecosystem.
