How Deep is Lake Erie?

Lake Erie is the shallowest of the Great Lakes, but still deep in places. Here are the key depths to know about Lake Erie depth:

LocationApprox. Depth
Western Basin25-30 feet
Central Basin60-90 feet
Eastern Basin80-210 feet

Average Depth: 62 feet (19 meters)

  • This makes Erie a great place for cold-water fish.
  • But it’s way deeper than you can dive without special equipment.

    Maximum Depth: 210 feet (64 meters)

    • The deepest parts are in the northeast, near Buffalo, NY.
    • That’s about as deep as a 20-story building is tall!

      Shallow Zone: Less than 25 feet deep

      • Covers about 25% of the lake’s total area
      • Found mostly in the Western Basin near Michigan and Ohio

        So while Lake Erie may be the most shallow Great Lake, it’s still one seriously big lake! Knowing the depths is key for boaters, fishermen, and divers.

        The depth of Lake Erie varies by geographic area. Lake Erie is broken up into three different basins. The western, central, and eastern basins. Each basin has its depth range that plays a major role in Lake Erie’s health. The depth of Lake Erie also plays a major role in the fish that live there. For example, the western basin is shallow and rocky allowing walleye and smallmouth to spawn. The central and eastern basins have more depth allowing for cold water species such as trout to thrive. Learn more about the depth of Lake Erie in each zone below.

        Lake Erie Western Basin Depth

        The Western Basin of Lake Erie is known for its relatively shallow depths compared to other parts of the lake. On average, the depth of the Western Basin ranges from around 10 to 25 feet (3 to 8 meters). However, there are deeper areas within the basin, particularly along the eastern and southeastern edges near the islands, where depths can reach up to 40 feet (12 meters) or more.

        These deeper spots are often popular among anglers targeting species like walleye, yellow perch, and smallmouth bass. It’s important to note that lake depths can fluctuate due to factors such as water levels, currents, and sedimentation. The Maumee and Detroit rivers enter Lake Erie in the western basin, this can cause sediment to enter the lake and change the depth in those areas. Dredges are often seen in these areas to keep the bottom deep enough for ships to enter the channels.

        Lake Erie Central Basin Depth

        Lake Erie Central Basin Depth

        The Central Basin of Lake Erie is deeper compared to the Western Basin, with depths varying across the region. On average, depths in the Central Basin range from approximately 25 to 60 feet (8 to 18 meters). However, there are deeper areas within the basin, particularly in the eastern and northeastern parts, where depths can reach well over 60 feet (18 meters). The areas along the US / Canadian border can reach depths exceeding 60 feet. Also, in Canadian waters, the depth can be significant. The Central Basin is characterized by its deeper waters, making it a suitable habitat for a variety of fish species, including walleye, steelhead trout, and yellow perch. Steelhead trout are particularly targeted in the central basin in 60-plus feet of water.

        Lake Erie Depth | Eastern Basin

        The Eastern Basin of Lake Erie features a wide range of depths, with some of the deepest areas of Lake Erie are found in this region. Depths in the Eastern Basin can vary, ranging from approximately 30 to 210 feet (9 to 64 meters). The easternmost parts of the basin, particularly near the international border with Canada, tend to have deeper waters. Additionally, the central and southern portions of the Eastern Basin have some of the lake’s deepest points, reaching depths of over 200 feet (61 meters) in certain areas.

        These deeper waters provide important habitat for various fish species, including lake trout, steelhead trout, and smallmouth bass. There is what is called a dead zone in the middle of the central and eastern basins. This is a deep area with little dissolved oxygen which is avoided by fish. The eastern basin is home to the head of the Niagara River, which is close to Buffalo, NY. This is where the waters of Lake Erie enter into Lake Ontario.

        Lake Erie Depth | Does it Ever Change?

        The answer is yes, the depth of Lake Erie changes every year. Lake Erie even has tides contrary to popular belief. The tides are there, but negligible to boaters since it is so little. Rainfall in the headwaters of Lake Erie is the biggest factor in the depth of Lake Erie. Significant rain in the recent past has raised the lake to 3 feet from its average. Wind can also change the depth of Lake Erie. Sometimes a gail wind will appear out of one direction pushing water to one side of the lake. This is called a seiche. A seiche can raise/lower the lake level by many feet. Boaters can avoid problems by checking the Lake Erie wind forecast often.
