Whitefish Lake Aquatic Invasive Species Management Program
A collaboration of the City of Whitefish, Whitefish Lake State Park, and the Whitefish Lake Institute

Watercraft Inspection and Decontamination 
As of spring 2017, it is mandatory to have all motorized and non-motorized watercraft inspected prior to launching in Whitefish Lake. High risk watercraft must also be decontaminated (Section 13-5-3 of the Whitefish City Code).

Whitefish City Beach Watercraft Inspection Station Hours

May 5:00 AM 9:00 PM
June & July 5:00 AM 10:00 PM

Whitefish Lake State Park Watercraft Inspection Station Hours
May – September  7:00 AM – 10:00 PM

The City Beach and Whitefish Lake State Park boat ramps will be chained or gated after staffed watercraft inspection hours. Boats coming off the lake after hours will be able to exit the lake by removing and replacing the chain. Motorized watercraft may not launch before or after staffed inspection hours.

Whitefish Decontamination Station Hours
Located at Whitefish Marine & Powersports (6191 U.S. Hwy 93 just north of JP Road)

June 16 – August 15 9:00 AM 8:00 PM
August 16 – September 30 5:00 AM 9:00 PM

Decontamination must be performed prior to launching in Whitefish Lake—whether or not you have been inspected at another inspection station—on all the following watercraft:

  • with ballast tanks or bags
  • that have been in a mussel infested waterway in the last 30 days
  • with standing water
  • that inspectors deem are too dirty to inspect

There is a $40 fee for decontamination.

Online Self-Certification Program - for Non-Motorized, Hand-Launched Watercraft Users

This Online Self-Certification Program for non-motorized, hand-launched watercraft users is designed to get low risk watercraft on the lake quicker and to alleviate congestion at the City Beach and Whitefish Lake State Park boat launches. By participating in this program, users have the opportunity to acquire an annual Sticker that will eliminate the need for a full inspection each time they visit the lake. In order to obtain an annual Sticker, non-motorized, hand-launched watercraft users are required to complete an on-line training course and demonstrate they have acquired knowledge via a test. If the user successfully passes the test, they will be issued a Certificate and a Sticker that can be displayed to boat inspectors at City Beach and Whitefish Lake State Park. Non computer users who want to take the test manually may do so at the City Beach and Whitefish Lake State Park boat launches.

This program is built on the assumption that we all care about keeping AIS out of our local waterbodies. Once you have a sticker, it is your responsibility to clean drain and dry your watercraft after visiting any other waterbody before launching again in Whitefish Lake.

All Watercraft Off-Season (October 1 – April 30)
The City Beach and Whitefish Lake State Park boat ramps will be chained/gated and locked in the off season. All motorized and non-motorized watercraft users may launch at these sites in the off season by demonstrating via the Online AIS Self-Certification Program they have acquired the appropriate knowledge. Users who successfully pass the program test will be issued a certificate and lock code to enter and exit the boat ramps at City Beach and Whitefish Lake State Park.
