Chesapeake Bay Trivia Questions

Bay water is brackish—less salty than the ocean. Freshwater from rivers dilutes saltwater from the Atlantic, with salinity increasing toward the mouth.

Opened in 1964, this 17.6-mile engineering marvel crossing the mouth of the bay is one of just a handful of bridge-tunnel complexes globally.

Thomas Point Shoal Lighthouse, built in 1875, is still an active aid to navigation and the only screw-pile lighthouse on the bay in its original location.

Actually, over 3,600 species of plants and animals inhabit the watershed, including 350+ fish species—far exceeding just 100.

While blue crabs faced declines, recent population surveys show healthy rebounds thanks to management, and they are not critically endangered—still sustainably harvested.

Historically, oysters filtered the entire bay in days. But due to overharvesting and disease, the current population would take over a year to do so.

The Chesapeake Bay impact crater, buried under the southern bay, was caused by a massive asteroid or comet, shaping the region's geology and groundwater.

Near Bloody Point, the bay plunges to about 174 feet, but a deeper 'Hole' reaches 210 feet, created by ancient river channels and tidal scouring.
