Lake Sullivan water quality testing

Lake Sullivan Association has been submitting water samples and testing water clarity since 2008. Steve Pavelka, our tester, recently completed his sampling for this year and all samples have been submitted to RMB Environmental Laboratories. RMB provided the data for the following reports showing how Lake Sullivan is faring during the testing and how we compare with other Morrison County Lakes. You can explore the topic further with Primer on Lake Limnology and preparing your own reports with their Lakes Database.

Become an LSA Landing Ambassador

The Lake Sullivan Association Landing Ambassador Program (LAP) is a part of the MN Department of Natural Resources fight to control aquatic invasive species (AIS) at the two landings on Lake Sullivan. Successful applicants will greet boaters as they arrive at our landings and offer AIS information and to assist them to ensure that no AIS are introduced into Lake Sullivan. In addition, they will offer assistance to boaters as they leave Lake Sullivan to ensure that all AIS laws and regulations are followed.

Ambassadors must participate in DNR Ambassador training, which will include a background check, and most likely will be held in Sauk Rapids, MN. Hours in training will be paid and mileage expenses to attend training will be reimbursed. The date of training will be determined in the near future. A number of Ambassador positions will be available.

Our landings will be staffed by Ambassadors Saturdays and Sundays and holidays between May 13, 2017 and September 17, 2017. The Ambassadors will have 8 hour shifts on their assigned days. This program will include a total of 20 days of coverage/employment on each landing for a total of 640 hours for the season. Individuals who earn $600 or more for the season will be given an IRS 1099 report of earnings for federal and state tax purposes.

Two types positions are available (applicants can apply for both):

LAP Coordinator: One individual who will assist with the hiring of Ambassadors and be responsible for managing Ambassadors, maintaining a calendar of coverage, spot checking to ensure Ambassadors are on site, and submitting payroll information each month for hours worked. The LAP Coordinator may schedule him/herself as an Ambassador. The LAP Coordinator will be paid $750 for the season, receiving $125 per month for the six months of the season. The LAP Coordinator pay is above and beyond any pay earned while serving as an Ambassador.

LAP Ambassador: Individuals serving as greeters at the landings – 8 hours a day. Pay for an Ambassador will be $12.50 per hour with time and half for holidays. In addition to the training, and required background check applicants, must be at least 18 years of age by May 13, 2017.

Lake Sullivan 2016 vegetation report

Freshwater Scientific Services conducted a lake-wide aquatic plant survey for Sullivan Lake on August 2-3, 2016 using the point-intercept method described by Madsen (1999). This survey incorporated assessments at a total of 219 sample points arranged in a uniform grid (125-m spacing; Figs 1 and 2). These sample points were positioned to match the locations used for the 2008 DNR survey. We loaded these selected sample points onto a handheld GPS unit (Garmin GPSMAP-78) for navigation to each point while in the field.

At each designated sample location, we collected plants using a double-headed, 14-tine rake on a rope. For each rake sample, we dragged the rake over the lake bottom for approximately 5 ft before retrieving. Retrieved plants were piled on top of the rake head and assigned density scores from 1 to 4 based upon rake head coverage (Table 3) for each individual species and for all plants collectively.

Study identifies hundreds of impaired Minnesota lakes and streams – including Lake Sullivan

LSA ImpairedScientists have identified pollution in hundreds of additional Minnesota lakes and streams.

The new update comes as the state is partway through a 10-year project to monitor water quality in all 80 Minnesota watersheds. Every two years, the Minnesota Pollution Control Agency announces results from another round of monitoring.

With the new additions, there are just under 3,000 total lakes and stream segments marked as impaired in some way across Minnesota.

“It’s essentially a running accounting of where we’ve found problems across the state and the nature of those problems,” said Shannon Lotthammer, director of MPCA’s environmental analysis and outcomes division. “We need to identify them as impaired so we can come up with a plan for fixing the problem.”

Generally speaking, Minnesota’s waters are cleanest in the northeastern part of the state and are least clean in the southwest. Population density, development, industry and agriculture can all contribute to a lake’s or stream’s impairment.

MPCA is three-quarters of the way through its first 10-year cycle of assessments, paid for by the Legacy Amendment voters approved in 2008. Early next decade, scientists will start the cycle over again, revisiting waters they examined in past years.

The new additions for the 2016 update were concentrated in a few parts of the state: a cluster of watersheds in south-central Minnesota, another cluster in north-central Minnesota, and a cluster by the Red River in the northwestern part of the state.


  • There are just under 3,000 total lakes and stream segments marked as impaired in some way across Minnesota.
  • Added in 2016 were watersheds clusters in south-central and north-central Minnesota, and by the Red River in northwest Minnesota.
  • Some of the impaired lakes have dangerous toxic chemicals; others are perfectly safe to swim in but have damaged ecosystems.
  • Bigger list doesn’t mean pollution is getting worse. Rather, state hadn’t surveyed most of these rivers and lakes before.

2016 4th Of July Boat Parade

Warm weather and sunny skies greeted LSA’s 2016 July 4th Boat Parade on Lake Sullivan. Many red-white-and-blue decorated boats loaded with patriotic passengers gave onlookers an afternoon of ooohs and aaahs. The day concluded with fireworks lighting up the skies of Lake Sullivan.

Lake Sullivan Ice Out History

Lake Sullivan’s ice out date for 2017 was March 31st. The definition of lake ice-out varies from lake to lake, and individual to individual. For some, ice out occurs only when the lake is completely free of ice. For others, ice out is defined as the moment when navigation is possible from point A to point B. And yet for others, ice out is when 90 percent of the lake is ice free.

Lake Sullivan:
Median ice out date: April 19
Earliest ice out date: March 19, 2012
Latest ice out date: April 29, 1996
Period of record: 1989 to 2014

LSA’s Mission Statement

As the Lake Sullivan Association has evolved over time, its important to review and validate that the LSA Mission Statement keeps the organization on it’s desired track.  Some reasons to review a Mission Statement –

  1. If the organization has achieved it’s mission and/or problem has been solved.
  2. If the business environment (financial, regulations, customers) has changed.
  3. If the statement allows the organization to change and grow.
  4. If the organization’s mission is still relevant.


The Lake Sullivan Association is a non-profit 501(c)(3) organization dedicated to improving lake quality and fellowship to enhance the lives of association members, property owners, and visitors of Lake Sullivan.
