The operation was carried out between last Thursday and Sunday and involved Officers from the Hume and Camden Police Districts, National Parks, Water NSW and the Department of Primary Industries.
It targeted restricted areas set up to protect Sydney's water supply.
Over the three days the team attended a number of remote rural properties and campsites and spoke with campers and residents.
They also inspected a number of locks and gates.
Police carried out 270 breath tests on public roads which resulted in one drink driving charge and searched 13 vehicles which also resulted in two firearm offences and three drug possession charges.
