Montgomery County Fire and Rescue Service was dispatched Thursday afternoon to a water rescue near the Virginia side of the Potomac River.
One person, who did not appear to be injured, was in the water around the observation deck below Great Falls, according to Captain Oscar Garcia, spokesperson for MCFRS. Garcia was unable to confirm gender or age of the victim.
The individual was being transported to Virginia where MCFRS would do a physical assessment of the victim's condition and transport him or her to a hospital if needed, Garcia said.
Authorities believe the victim slipped and fell into the water.
According to Garcia, MCFRS response to Virginia-side Potomac River rescues are common due to the geography of the area. Emergency 911 calls are often dispatched to Maryland rescue teams.
