Lake Michigan’s depth varies by location, but you can rely on two key figures:

• Average depth: about 279 feet (approximately 85 meters).
• Maximum depth: about 925 feet (roughly 281 meters), found in the deepest troughs of the lake.

If you need the depth for a specific site on Lake Michigan (e.g., near a particular shore, harbor, or basin), I can look up that location and give you the precise figure.
