Sept 19, 2019

The recent rains have caused water levels in the Briggs Lake Chain to rise above the 964.2 foot mark. This triggers the ‘SLOW-NO WAKE’ restriction in Palmer Township (Ordinance no. 104) and Clear Lake Township (Ordinance no. 4). Notices have been posted at the public accesses of Briggs, Julia, Rush and Big Elk.

What does This Mean for Fishermen and other Boaters?

Boaters must reduce speed and eliminate wakes anywhere on the lakes. “SLOW-NO WAKE” is defined in Minnesota Statutes 86B005 as “the minimum speed necessary to operate a watercraft but no more than five [5] miles per hour.” Be aware the “no wake” rule will be enforced by the Sherburne County Sheriff's Office and other appropriate licensed peace officers. Violators are guilty of a misdemeanor.

The “no wake” restriction will remain in effect for three consecutive days after the water level has subsided below the 964.2 foot level at which point you will be notified.

Thank you for your cooperation in helping to reduce shore land erosion and property damage during these high-water periods.

Boat inspection hours (Sherburne County)

WaterGuards have completed their AIS inspections for 2019.  The table on the left shows the total hours of effort at numerous public landings in Sherburne County.  In all, we reached 1,387.75 hours of inspection. 

In the coming months data collected by both inspectors and data submitted by AIS volunteers will be shared when available.

Thanks to all for your continued efforts to protect our lakes!

  • (EWM) was detected on Rush Lake during the survey to map the 2014 treatment areas for the invasive curlyleaf pondweed that infests Briggs, Rush and Julia.

  • Make double sure boats, trailers, jet skis, docks, swim platforms, etc. are carefully inspected, properly  cleaned and dried before they are transported from our lakes.

Determining weather there is EWM or Northern milfoil takes practice.

Oak Wilt

Winter is the time to get the dead oak branches trimmed and removed.


We live in Oak Wilt territory and are in the highest danger season April, May and June for spreading Oak Wilt. While all species of oak can be affected, oaks in the red oak group (oaks with pointed lobes on their leaves) are by far the most susceptible and are probably the most abundant tree in our yards. Northern red and pin oaks can die within two to three months of infection. White oaks are the most resistant and may survive for years after infection. Bur oaks are intermediate and may die within two to three years of infection.

Emerald Ash Borer


Emerald Ash Borer (EAB) has killed millions of ash trees since 2002.
Minnesota currently has the largest Ash tree population in the United States. 
Don’t move firewood to or from your lake home from long distances.
(You typically can’t see if firewood is infested or not, so why take the risk?)
Emerald Ash Borer is on its destructive path (CLICK HERE FOR KARE 11 STORY) 
It is spreading too!  Now only 6.5 miles east and southeast of Elk River:  (CLICK HERE FOR MAP) 
Early detection is critical to minimizing tree loss and the subsequent loss of environmental benefits.  

Want to help the lakes? Join the AIS Detectors!

Participants in the AIS Detectors program receive expert training on identifying and reporting AIS as well as base aquatic ecology, prevention, MN rules and regulations training and more. Upon completion of the training, participants are asked to provide 25 hours of annual service in the field of aquatic invasive species. This service can take many forms that we generally categorize as Citizen Science, Stewardship, Outreach/Education, and Program Support. This may include activities specific to your lake or lake area such as monitoring for AIS and local outreach/education. Participants choose what form of service suits them best and are free to create grassroots projects or service. You can find more information at www.aisdetectors.org.

We hope this is an opportunity that may interest you and your members.Click on link to see video or push button for PDF information.

What does it mean to have an "impaired" lake?

The definition of impaired for a lake like Julia is to exceed 60ug/liter of phosphorus.

Lake Julia has about 1.48e+9 liters of water. Meaning to be impaired it takes about 196 pounds of the stuff. See why phosphorus is against the law to put on your lawn?
