Taylor Erickson, 29, was charged with causing a false public alarm and making a false report to law enforcement.
The incident happened Saturday evening in the area of 25th Avenue and the beach.
The North Wildwood Police Department said Erickson reported that a juvenile male brandished a gun, then entered the Surfside Pier section of Morey's Piers.
Erickson gave officers a detailed description of the suspect, as well as a description of the gun, police say.
That prompted a police response and the evacuation of Surfside Pier.
However, police say they were able to locate the juvenile and he was confirmed not to be in possession of a gun.
The pier was reopened a short time later.
Investigators went on to say they conducted witness interviews and viewed surveillance video but were not able to find any evidence of someone brandishing a gun.
During a follow-up interview, police say Erickson admitted to creating a false report after she got into a verbal dispute with the juveniles.
Erickson was placed on a summons and released pending a court date.
