Dolphin sightings aren't uncommon in Chesapeake Bay tributaries. Seeing one in a freshwater tributary of the Chickahominy River got a Virginia aquarium's attention.

The Virginia Aquarium and Marine Science Center says higher water levels from Hurricane Irene may have caused a bottlenose dolphin to venture into Diascund Creek.

Aquarium spokeswoman Joan Barns said Thursday the dolphin has
been in the area for at least three days.

The 6-to-8 foot dolphin is swimming freely, although an effort to gently nudge the dolphin south beyond a reservoir was unsuccessful.

Barns says the dolphin's progress will continue to be monitored.
