The Great Lakes share a surprising connection with Wisconsin's small lakes and aquifers — their water levels all rise and fall on a 13-year cycle, according to a new study. But that cycle is now mysteriously out of whack, researchers have found.
water levels = (rain + run-off) - (evaporation)Over the past five years, water levels in Lake Michigan have risen because we've been experiencing both heavy rain and reduced evaporation (the latter driven by smaller differences between lake and air temperatures).
The Great Lakes water levels currently are controlled by several factors, including the Soo Locks, which regulate the outflow from Lake Superior, and five diversions that transfer water in and out of the Great Lakes basin, including the Welland Canal, which connects lakes Erie and Ontario.
The record-breaking water levels this summer can be attributed to tremendous amounts of precipitation and excess runoff during the spring and summer. The Great Lakes region saw above-average rain for the three consecutive months from April to June, contributing to the overflowing basins.
Sharks literally just can't get to the Great Lakes. While they can hang out in the Great Barrier Reef, there are a few barriers like an electrical one in Chicago, locks and dams in the Illinois River and even Niagra Falls, as Great Lakes Guide said.
The five Great Lakes - Superior, Huron, Michigan, Erie and Ontario - span a total surface area of 94,600 square miles and are all connected by a variety of lakes and rivers, making them the largest freshwater system in the world.

5 Things You Can Do To Protect The Great Lakes
- Watch What You Wash. One load of laundry can release more than 700,000 microscopic plastic fibers into the water system, polluting our waterways and disrupting the food chain.
- Go Fertilizer-Free.
- Ditch the Aquatic Hitchhikers.
- Dispose of Meds Properly.
- Get Political.
Though the five lakes lie in separate basins, they form a single, naturally interconnected body of fresh water, within the Great Lakes Basin. As a chain of lakes and rivers, they connect the east-central interior of North America to the Atlantic Ocean.
The Great Lakes are connected to the Atlantic Ocean through the St. Lawrence Seaway. Together, the Great Lakes and the St. Lawrence Seaway form the largest surface water system on the planet.
A retreating glacier often left behind large deposits of ice in hollows between drumlins or hills. As the ice age ended, these melted to create lakes. These lakes are clearly visible in aerial photos of landforms in regions that were glaciated during the last ice age.
LONSHORE CURRENTSLongshore currents are caused by winds and waves hitting the shoreline at an angle and pushing water down the length of the beach in one direction. People caught in a longshore current can find themselves far down the beach from where they entered the water.
According to the U.S. Army Corps of Engineers, Lake Michigan-Huron — for measurement purposes the two lakes are considered one as they connect at the Straits of Mackinac — has broken high water level marks every month of 2020. The trend is expected to continue at least until September.
The record low lake level for Lake Michigan-Huron was 576.0, International Great Lakes Datum (IGLD) 1985, in March 1964 (preliminary data indicates we reached a new record low in January 2013) and the record high was 582.3, IGLD 1985, in October 1986.

Michigan is projected to see a five-fold increase in heat wave days by 2050. By 2050, the severity of widespread summer drought is projected to triple in Michigan. This would result in a severity index greater than Texas' current threat from widespread summer drought.
Everyone will move to Michigan in 2100 due to climate change, Popular Science says. Popular Science arrived on Michigan using a process of elimination, predicting that in 2100: "Sea levels could rise up to 6.6 feet." This eliminated most areas on the Pacific and Atlantic Oceans.
Changing the climate is likely to increase the frequency of floods in Michigan. Changing the climate is likely to harm water quality in Lake Erie and Lake Michigan. Warmer water tends to cause more algal blooms, which can be unsightly, harm fish, and degrade water quality.
Winds from the north over Lake Michigan cause currents in the water to push toward the west over time. Through upwelling this chilly water will eventually make it to the surface, replacing the warmer water that has moved toward the west.
Lake Michigan has been almost exclusively a man-made ecosystem for nearly a century, according to the fisheries biologists charged with stewardship of the lake.
True tides—changes in water level caused by the gravitational forces of the sun and moon—do occur in a semi-diurnal (twice daily) pattern on the Great Lakes. Consequently, the Great Lakes are considered to be non-tidal. Water levels in the Great Lakes have long-term, annual, and short-term variations.
Large parts of Michigan have had over 16 inches more rainfall than average in the past year. So it's a clear and simple reason why the Great Lakes are so high- heavy precipitation over the last five to 10 years. Water is taken out of the Great Lakes through a few routes- the St.
According to the map above and NOAA reports, surface temperatures are 6° to 10° Fahrenheit (3° to 5° Celsius) above normal for early July. The average lake water temperature across all of Lake Erie—the shallowest lake—was 74.29°F on July 15; it was 59.83°F across Lake Superior, the largest lake.
Species native to the lake include: banded killifish, bloater, brook trout, burbot, cisco, lake sturgeon, lake trout, lake whitefish, longnose sucker, muskellunge, northern pike, pumpkinseed, rock bass, round whitefish, smallmouth bass, walleye, white sucker and yellow perch.
