I chose titled topic by a fanciful whim,
nevertheless still consider my knowledge
of aforementioned material slim.

Huron, Erie, and Ontario dearth
Largest group of freshwater lakes on Earth
Straddle Canadian–United States border
tethering partial global girth
Constituting 21% of world's surface

Total surface equals 94,250 square miles
And total volume equals 5,439

Lake Erie from Erie tribe, abridged form
of Iroquoian word erielhonan “long tail”
Lake Huron named by French explorers for
Wyandot or “Hurons” whence they did sail
Lake Michigan likely from Ojibwa word
mishigami “great water” aka outsize gold quail
Lake Ontario i.e. “Lake of Shining Waters”
shimmering like hammered coat of mail
Lake Superior coined from French “lac supérieur”
"upper lake", an emerald watery dale
Ojibwe people called it gitchigumi medicinal
to cure that, which might ail.
These five lakes each reside in separate basin
Form a single, naturally interconnected body
of fresh water caisson
Linking east-central interior of North America
to Atlantic Ocean akin to an escutcheon.
From interior to outlet at St. Lawrence River,
Water flows via Superior to Michigan-Huron
southward to Erie to avoid a shiver
Finally released northward to Lake Ontario
as like a well taut archer with his quiver.
The lakes drain a large watershed via many
rivers as an Olympic team
Populated with approximately 35,000 islands
this estimate not x stream.
The Great Lakes region contains many
thousands of smaller lakes,
Often called inland lakes undulating in
delving, cascading and brimming
analogous to a fluid ream
Lake Michigan the only one located
entirely within United States
While the others border between United States
and Canada – essentially a liquid seam.
Lakes Michigan and Huron
are basically a single lake,
Sometimes called Lake Michigan-Huron,
combined doth make
Total area of 45,300 square miles (117,000 km2)
Have the same surface elevation of 577 feet (176 m),
Connected by 295-foot deep Straits of
Mackinac Islands splayed like a rake.
Approximately 35,000 islands
extant throughout oceanic like sea
Largest among them
Manitoulin Island in Lake Huron
brushing up against Goliath knee.
The second-largest island is Isle Royale in
Lake Superior to boot
Both these islands
contain multiple lakes themselves
alive with creatures that hoot.
Unadulterated details gleaned courtesy
Mister Google, which website
buried under virtual sediment:
The Saint Lawrence Seaway
and Great Lakes Waterway connect
the Great Lakes to ocean-going vessels.
The move to wider ocean-going container ships —
which do not fit through the locks on these routes —
has limited container shipping on the lakes.
Most Great Lakes trade constitutes bulk material
and bulk freighters of Seawaymax-size
or less can move throughout
the entire lakes and out to the Atlantic.
The Great Lakes also connected
to the Gulf of Mexico
by way of the Illinois River
(from the Chicago River)
and the Mississippi River.
An alternate track is via the Illinois River
(from Chicago), to the Mississippi,
up the Ohio, and then
through the Tennessee-Tombigbee Waterway
(combination of a series
of rivers and lakes and canals),
to Mobile Bay and the Gulf.
Commercial tug-and-barge traffic
on these waterways quite heavy.
Pleasure boats can also enter or exit
the Great Lakes by way of
the Erie Canal and Hudson River in New York.
The Erie Canal connects to the Great Lakes
at the east end of Lake Erie
(at Buffalo, New York)
and at the south side of Lake Ontario
(at Oswego, New York).
The Great Lakes contain 21%
of the world’s fresh surface water:
5,472 cubic miles (22,810 km3),
or 6.0×1015 U.S. gallons (2.3×1016 liters).
This equals enough water
to cover the 48 contiguous U.S. states
to a uniform depth of 9.5 feet (2.9 m).
Although the lakes contain
a large percentage of the world's fresh water,
the Great Lakes supply only a small portion
of U.S. drinking water
on a national basis (roughly 4.2%).
Winter 2009–10 ranked somewhat mild,
the precipitation was below normal
for the Great Lakes Basin.
Mean lake levels then thought
to be slightly below
or at their levels of 2009.
An ice jam in February 2010
dropped the level in Lake St. Clair.
Since the jam got removed the level
has come back to its average.
As of March 2010, the lakes
were at the level, or slightly below,
where they were in March 2009.
The combined surface area
of the lakes equals approximately
94,250 square miles (244,100 km2)—
nearly the same size as the United Kingdom,
and larger than the U.S. states of New York,
New Jersey, Connecticut, Rhode Island,
Massachusetts, Vermont,
and New Hampshire combined.
The Great Lakes coast measures
approximately 10,500 miles (16,900 km);
however, the length of a coastline
impossible mission to measure exactly
cuz topographical feature not well-defined.
