Green Lake County Crime Stoppers

For more information visit

Green Lake County Crime Stoppers Incorporated, formed in 1993, is a non-profit 501c3 organization run by a board of 10 citizens. Green Lake County Crime Stoppers is a member in good standing of both the State of Wisconsin Chapter and Crime Stoppers USA National.

The Crime Stoppers board meets monthly at the Green Lake County Safety Building to discuss the organizations affairs, plan activities, and act upon rewarding tip information. Crime Stoppers is truly vested in service to the community by combating crime at all levels.

Programs operated by Green Lake County Crime Stoppers include:

  1. Quick 50 Program in the Schools
  2. Green Lake County “Most Wanted” for warrants
  3. Liaison with Law Enforcement for the “Crime of the Week”
  4. Mentor a safe community concept via promotional items at the County Fair, Community events, and parades.

How does Crime Stoppers work? There is always someone who has information that can help solve crime.Those are the people who can call Crime Stoppers anonymously and provide a tip that will help all police jurisdictions in the County identify those responsible. Crime Stoppers shares its tip information with all jurisdictions regardless of Village, City, County, or State.

In any investigation police and other law enforcement agencies encounter individuals who will not directly provide information. The three key reasons are:

  1. Fear of reprisal
  2. An attitude of apathy
  3. Reluctance to get involved

Crime Stoppers breaks through these barriers by giving people the opportunity to provide information without directly speaking to the police or having to testify in court. Obviously investigators need witnesses to help prove their case in court, but most importantly they need information that allows them to zero in on a suspect or a criminal operation.Tips to Crime Stoppers does not give police the evidence they require to arrest an individual but puts them on the right track to solve crime.

Cash rewards from Crime Stoppers also motivate some people to call anonymously with information that will be vital to the police.However, you don’t have to receive a cash reward if you don’t want one. The important part is to call and do the right thing.

Lasting Impressions Forever LIFE

The Green Lake County Sheriff’s Office, local Police, local government, and the schools take a pro-active stance in educating, understanding, and relating to the Counties students and youth. In 1993 a coalition of professionals came together to create the program formerly titled, “Resist and Prevent” RAP program. Similar yet different from other anti-drug public education programs RAP built the relationship between government, law enforcement, and youth by establishing good communications and a relationship. Being able to relate and communicate translates into a mutual understanding of three major life skills. These three major life skills, restraint, respect, and responsibility are the foundation of the now LIFE program.

Within a six week process, during the school year, full-time uniformed police personnel expose students to the role of the police officer. Students are also taught the dangers of alcohol, tobacco and drug abuse. Youth are instructed concerning skills on refusing substances, anger management, bullies and harassment. Internet safety also has become a valuable segment of the program.

While no program is 100% successful everyone involved with the LIFE program is truly committed to making a difference within the community.

Boat/Recreation Patrol

The Green Lake County Sheriff’s Office operates recreation patrols within Green Lake County. These patrols place law enforcement staff upon snowmobiles and watercraft during their respective seasons. Deputies work with the Wisconsin Department of Natural Resources in patrolling the hundreds of miles of snowmobile trails and thousands of acres of waterways within the County. The Sheriff’s Office issues approximately 60 citations per year for recreational offenses. The Sheriff’s Office also participates in safety related trainings involving recreational vehicles.

Complaints involving watercraft, snowmobile, or all terrain vehicles (ATV’s) may be reported to:
Green Lake County Sheriff’s Office: Ph#:920-294-4000 or
Local Wisconsin DNR Office: Ph#: 920-361-0333

Snowmobile Safety

Stay On Marked trails. 
Your local snowmobile club has provided safe trails for you to operate your snowmobile. Accidents involving hidden objects under the snow or problems with private landowners have occurred when snowmobilers fail to stay on marked trails. Be alert for fences, tree stumps and stretched wire that may be concealed by snow. Respect the property of the landowners and stay on marked trails.

Road & Railroad Crossings. Always come to a complete stop and look both ways before crossing any road or railroad crossing.

Slow down. Speed is a contributing factor in nearly all fatal snowmobiling accidents. Drivers should proceed at a pace that will allow ample reaction time for any situation. Drive at moderate speeds, and drive defensively, especially after sunset.

Carry a first-aid kit and dress appropriately. Your first-aid kit should include a flashlight, knife, compass, map, and waterproof matches. Wear layers of water-repellent clothing and make sure you have no loose ends that might catch in the machine or tangle in equipment.

Bodies of Water. Avoid traveling across bodies of water when uncertain of ice thickness or water currents. Rapidly changing weather and moving water in streams and lake inlets also affect the thickness and strength of ice on lakes and ponds. Snow cover can act as a blanket and prevents thick strong ice from forming.

Be Safe, Wear a Helmet. Use a full face helmet, goggles or visor to prevent injuries from twigs, stones, ice chips and flying debris.

Never Travel Alone. Most snowmobile accidents result in personal injury. The most dangerous situations occur when a person is injured and alone. If you must travel alone, tell someone.

Snowmobile At Night. When snowmobiling at night, do not override your lights.

Who Can Operate a Snowmobile? Any person who is born on or after January 1, 1985 and who has reached the age of 12, must have completed and received a snowmobile safety certificate in order to operate a snowmobile in Wisconsin. The certificate must be carried while operating the snowmobile and displayed to a law enforcement officer upon demand.
