Lyon County employs five full time dispatchers and one part time dispatcher.  Dispatchers answer all business calls, 911 calls and monitor over ten radio frequencies. In addition, the communications center answers many alarms for businesses throughout the county and dispatches the appropriate responders. The communication center is open 24 hours a day, 365 days a year.  All law enforcement, fire departments, rescue units and ambulances for the county are dispatched by the communications center.

Dispatchers are fully trained and certified in IOWA/NCIC and must have eight hours of continuing education every year and re-test every two years.  Because of this specialized training dispatchers can access the IOWA/NCIC database for information needed by officers including driver’s license status, license plate information, criminal histories and wanted checks.  


When a call for service is taken the dispatcher enters the information into a Computer Aided Dispatch program in which everything pertaining to that call is tracked including call type, units dispatched to the call and their times. In a typical year Lyon County Communications handles over five thousand emergency and non-emergency calls for service.


As the dispatch administrator, Luann Serck is in charge of all the dispatchers, writing the schedule, updating and maintaining the equipment, and acts as a liaison between the Sheriff and the dispatchers. If you need to contact her for any dispatcher concerns you may contact her at 712-472-8300 or via e-mail luann.serck@lyoncountyia.com.


If you need assistance or wish to report a crime, please contact (712) 472-8300 or you may contact them at dispatch@lyoncountyia.com.

When should I call 9-1-1?

You should call 911 if you have situation requiring immediate action by emergency responders or have a situation in which there is an imminent threat to life or property.

Some examples:

• report a traffic accident

• report a fight in progress

• report a serious illness or injury that requires immediate medical attention

• report suspicious activity in progress

When should I not call 9-1-1?

You should not call 9-1-1 to report a situation that does not require immediate action.

Some examples:

• to ask for a phone number – that is what 411 is for

• to report a vandalism or theft after the suspect is gone

• to report your neighbor’s dog getting into your garbage

• as a joke (from a pay phone for example)

We are required to send law enforcement to any land line hang up call or any call where a person will not (or cannot) verbally respond. We will also try to send law enforcement to the general area of a cell phone call. It is a criminal offense to intentionally abuse 9-1-1!

Why do dispatchers ask so many questions when I call 9-1-1?

Emergency dispatchers need to rapidly obtain accurate information so they can send emergency responders to a scene. Callers will be asked: Where, What, Who, When and maybe Why.

Do you know my location when I call 9-1-1 from my cell phone?

That depends on several factors including the location of cell phone towers but most often we cannot pinpoint your exact location but only locate you within a several block or several mile radius. Therefore  it is important for you to give as accurate a description of your location as possible.

How do I get in touch with a certain deputy?

Home phone numbers of off duty officers will not be given to the general public.  If the deputy is working, they will be dispatched to your location or they may call you if a phone number is available. If you need to speak to a certain officer, please refer to our Deputy Information on the home page. There you will have access to their direct office number and their e-mail address.
