Sheriff boatThe King County Sheriff Marine/Dive/Rescue Unit is responsible for law enforcement on all lakes, rivers and other waters within the unincorporated areas of the county as well as in several cities that contract for our marine service, including regular patrols, law enforcement, emergency response, and boater safety education.

The King County Marine Unit also is responsible for missing swimmer rescues, for drowning victim recovery as well as documenting and recovering evidence underwater.

The Marine Unit patrols Lake Washington, Lake Sammamish, and numerous small lakes and rivers throughout King County. Safe and enjoyable boating for our community is our primary goal. To achieve this goal we make contact with violators and take appropriate enforcement action. We also attend and teach water safety education at community events, local schools and special water awareness on the beaches.

The unit’s deputies are specially trained in the following areas:

  • Boat handling
  • Small craft fire suppression
  • Marine laws and enforcement
  • BUI investigation
  • Boating Accident Investigation
  • Oil Spill Response
  • Police scuba diving
  • Underwater evidence processing

With experience, training and equipment, the Marine/Dive Unit provides valuable services to the citizens of King County and to those cities that contract for our marine services.

Dive and Swift Water Rescue and RecoveryDive Unit

The unit consists of highly trained SCUBA divers. Members of the unit are PADI dive master certified. They receive specialized training in evidence searches, drowning recoveries, and vehicle recoveries in lakes, rivers and streams throughout the county. To facilitate these functions, the unit uses underwater cameras, metal detectors, a small inflatable boat, and hands on experience in waters with little to zero visibility. Dive members also partner with community leaders and teachers throughout the state to teach enhanced water safety to our children and community. Further we work with all our communities for enhanced environmental awareness.

The unit also does swift water river rescue, recovery and evidence collection. The team trains frequently to remain proficient with river skills. The unit monitors hazards along the rivers and works to inform the public and river users of the natural hazards that exist to reduce the life safety risks for river users.
