Lakes are a Bing favourite because they photograph beautifully, so a shimmering crater lake or a vast inland sea regularly headlines the homepage with a quiz attached. The questions lean on a handful of famous record-holders, and knowing which record belongs to which lake wins most of them.

The record-holders to remember
Most lake questions circle the same champions: the Caspian Sea is the largest lake by area (salty and technically a lake), Lake Baikal in Russia is the deepest and holds the most fresh water, Lake Superior is the largest freshwater lake by surface area, and Lake Titicaca is the highest navigable lake, sitting between Peru and Bolivia.
Where the trick lies
'Largest' is the trap word. Largest by surface area, by volume, or freshwater versus saltwater all give different answers, so match the exact wording. A question asking the largest freshwater lake by area wants Lake Superior, while largest overall is the Caspian Sea, and largest by volume of fresh water is Baikal.
Example questions
Bing has asked which lake is the world's deepest (Baikal), which continent holds Lake Victoria (Africa, shared by Tanzania, Uganda and Kenya), and which famous crater lake sits in Oregon (Crater Lake, the deepest in the United States). When the image shows a specific lake, the caption almost always names it.
Answering fast
Identify the lake from the caption, then search its name with the specific fact. For record questions, include the qualifier in your search, 'deepest lake' or 'largest freshwater lake by area', so the answer matches the category being asked.
Frequently Asked Questions
What is the largest lake in the world?
The Caspian Sea by overall area. If the question specifies freshwater by surface area, the answer is Lake Superior, and by volume it's Lake Baikal.
What is the deepest lake in the world?
Lake Baikal in Siberia, Russia, which is also the world's largest freshwater lake by volume.
Why do lake questions feel tricky?
Because 'largest' can mean area, volume, or freshwater only. Match the exact qualifier in the question to the right record-holder.
