Marine Enforcement Unit

 The deputies in the Calcasieu Parish Sheriff's Marine Division are dedicated to providing the highest standard of law enforcement services to the citizens of Calcasieu Parish, along with visitors, on our waterways.  They patrol more than 325 square miles of waterways in Calcasieu Parish. The #1 goal is public safety on the waterways of Calcasieu Parish.


The marine division receives a number of calls each year ranging in nature from facilitating boater safety classes to the general public, marine regulations questions, requests for help, boating accidents, missing vessels and lost persons, as well as, stolen and suspicious vessels. The deputies assigned to this division are tasked with patrolling our waterways providing search and rescue operations, enforcing boating safety laws, responding to emergency calls, investigating boat thefts, assisting with boating and watercraft accidents, investigating criminal activity and conducting counter-terrorism patrols of our industrial installations, power plants and other high volume maritime assets.  Monitoring our port and critical infrastructure is necessary in securing our homeland security.

To maximize deployment and achieve greater flexibility in personnel, marine deputies utilize a number of diverse vessels and vehicles for marine enforcement patrols.  The fleet currently include several flat bottom aluminum boats, three 24 foot fiberglass bay boats, two air-boats and one 38 foot Catamaran boat. These vessels greatly enhance the Calcasieu Parish Sheriff's Office's ability to enforce local, state, and federal laws.

Most of the deputies assigned to this division maintain various dive certifications.  They conduct numerous dive operations year round.  These operations range from black water training dives to underwater recovery of drowning victims and/or forensic evidence.  These divers also utilize some of the most current sonar technology available while conducting these operations.

Complete this form before boating and leave it with a reliable person who can be depended upon to notify the Sheriff Department or Coast Guard or other rescue organization in case you do not return as scheduled.  Do not try to file this form with the Coast Guard, they do not accept float plans. 

A word of caution: In case you are delayed, and it is not an emergency, inform those with your float plan, the police and/or Coast Guard of your delay in order to avoid an unnecessary search.

Narcotics Department



The Drug Enforcement Department of the Sheriff's Office is the largest member agency in the C.A.T. Task Force. All of the local law enforcement agencies within Calcasieu Parish have combined resources and work together to fight the war on drugs.


The task force is divided up into three teams. The first team conducts undercover operations throughout Calcasieu Parish. The team utilizes paid assets who set up undercover narcotics purchases with known drug offenders.


The second team conducts knock and talk investigations. These investigations stem from information received from various sources. Information may come from the public, other agencies, and from people who have been arrested.


The third team targets those individuals and organizations moving quantities of narcotics and currency through Calcasieu Parish, via interstate, airport, bus terminal, etc. Narcotic sniffing dogs are a great tool which is used in detecting the presence of illegal narcotics as well as currency used in the illicit drug trade.


The personnel assigned to the drug enforcement efforts of the Sheriff's Office work around the clock in an effort to minimize the drug trade in Calcasieu Parish.


To report drug activity you may call the C.A.T. Task Force at 431-8001. You do not have to give your name.
