An anchor device and method for safely and reliably securing watercraft to the bed of a body of water is provided. The anchor device may include a handle member with detachable components and an auger. The auger may be bored into the ground upon rotation of the handle member and then detached from the handle member by lifting the handle member vertically. The auger may include a shaft with a square cross-section and a pointed bottom end. Two auger blades, separated by an axial gap, may be attached to the shaft. Each auger blade may extend circumferentially around the shaft in a helical configuration.
