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.

Lake Sullivan’s ice out date for 2020 was April 9th. 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.
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
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 –
- If the organization has achieved it’s mission and/or problem has been solved.
- If the business environment (financial, regulations, customers) has changed.
- If the statement allows the organization to change and grow.
- If the organization’s mission is still relevant.

Greetings Sullivan Lake residents and property owners. This past winter was another year of inadequate snow cover so we saw more ice push up and erosion problems this spring. It is inevitable on some lakes, worse on some sides than others, and no one really knows how to prevent it entirely.
Following are some of our observations and experiences on your lake and others in the county.
Ice push up might happen once in ten years or every year to some degree. It generally happens when the lakes do not have adequate snow cover over the ice, and the spring thaw is erratic. Thawing and refreezing again and again, creates blocks of ice and the expansion pushes into the shoreline and is a very powerful source of energy. No amount of rock rip rap or vegetation can prevent this type of damage.
As I said, rock rip rap does not prevent push ups. It might help in lighter ice years, and if the rock is angular and irregular in shape and size, that lends to a bit more protection. However, most rock used for rip-rap in this area is field stone and round. The rip-rap itself might wind up pushed up along with the shoreline and now you have an even bigger mess to contend with.
Most shoreline owners don’t want to hear about aquatic vegetation but none-the-less, the aeration that aquatic vegetation provides to the lake, is the best preventative to ice problems. It might still occasionally happen, but not as likely, and not as severely.
The introduction of aquatic plants requires a permit from the DNR Division of Aquatics but you may also be able to get some established by allowing some existing vegetation to expand a bit. Thin in terms of having adequate clearing for boat traffic and perhaps a bit of swimming but if you can resist eliminating too much vegetation, it helps.
Our office does have State Cost Share dollars that can assist if a landowner desires to replant the shoreline to native materials and is willing to allow for a minimum of 20’ of buffer. Riparian buffers is still an erosion control practice that reduces shoreline erosion from wave action and natural causes. It also aids in runoff from lawn chemicals and grass clippings. If you are mowing lawn down to the waters’ edge, you add phosphorus to the water which creates algae growth and you are diminishing the quality of your lake water.
If shrubs and trees aren’t acceptable to you, try designating a “no-mow” zone of 12-15 feet. Allowing the grasses to reach their full height will not only filter nutrients from entering the lake, but the root growth will increase accordingly and hold the soil better.
Rock rip-rap is still an acceptable alternative, but is vastly overused in our county, and particularly on Sullivan Lake. You do need a permit from Morrison County Planning and Zoning for rock rip-rap and possibly from DNR if the rock extends into the water more than 7 feet. Some homes and cabins don’t have room to allow trucks and equipment to get close enough to install rock and it can be installed on the ice if necessary but there is usually some small adjustments needed by hand the following spring.
A very reasonable alternative, and much cheaper is the use of bio-logs. We have been using them for the past several years on the river and other lakes, and find them to be a much more natural and less expensive way to address the undercutting of a shoreline. Undercutting is when the base of your shoreline is cutting away at the waters edge, creating a shelf. The shelf sloughs off, and the process starts all over again. Riparian buffers and bio-logs do not require any permits.
Plants alone can be used sometimes to address undercutting, but in other cases, we will recommend the use of the logs. The logs are made of a coconut fiber and come in 10 foot sections. They come in various diameters. The logs are secured with wooden pegs hammered into the shoreline and lake bottom, or can be tied with cables. Vegetation can grow right through the log and we sometimes ask the landowner to shove willow cuttings right through the log into the soil. When developed, the logs aren’t even seen, and it allows the shoreline to look natural.
Our staff is available for technical assistance in helping you design a buffer area or addressing your erosion problems. And again, we may be able to offer financial assistance, on a case by case basis. Our phone number is 320-616-2479 and ask for Helen or Alan. We will either visit your shoreline on our own with your permission, or meet you there by appointment and discuss the various options to help you protect your valuable shoreline property.
Erosion Control Tidbits from MORRISON SOIL AND WATER CONSERVATION DISTRICT By Helen McLennan
Engineers with the Minnesota Department of Natural Resources inspected the Lake Sullivan dam on April 14, 2015. This dam is exempt from Dam Safety Regulations but is inspected about once every eight years because it is owned by DNR.
The present dam was built in 1935 for lake level control and to prevent carp from entering the lake from the Mississippi River. In 1950 the catwalk was removed and all piers were shortened. The dam had six stop log bays with each being 5.75 feet wide. The dam presently has a concrete weir about 15 inches above the sill.
The existing dam is in fair to poor condition but it is functional and fairly stable. The concrete is in fair condition with several areas of exposed rebar and other concrete deterioration due to weathering. The concrete also shows signs of structural distress as evidenced by large cracks and leaning abutments.
The earthen embankments flanking either side of the dam are 1 to 2 feet below the concrete abutments. Embankments are lowest adjacent to both abutments, likely the result of shifting of the abutments. The dikes are stable. Routine mowing or other measures are recommended to control the growth of vines and brush.
Due to water flowing over the concrete weir Dam Safety was unable to evaluate the condition of the weir. The weir was repaired in 2007 to reduce leakage through the dam. At the time of this inspection no debris was in the spillway that would obstruct the flow of water.
Dam Safety is currently monitoring the dam and is committed to make necessary repairs to maintain current lake levels until funding to repair the dam is obtained. The dam is maintaining water levels as intended. Dam Safety did not observe any structural deficiency requiring immediate attention to maintain the dam in its current state. Future repair should address the tilting concrete abutments, repairing deteriorated concrete and adding earth fill to the embankment.
The 2015 Lake Sullivan Association picnic was hosted at the Circle of the Pines in Hillman on July 19th. Many LSA members and their families enjoyed an afternoon filled with food, fun and festivities.
Games included three-legged race, turnaround sprints, shoe kick, water balloon toss, egg toss and more!
Thank you LSA Picnic Committee for putting on such a great event!
The Sullivan Lake Association will not host Trash Day in 2015. But that doesn’t mean that there are not other options to help make your yard and Lake Sullivan a cleaner place!

Aquatic invasive species (AIS) are threatening Minnesota waters including Lake Sullivan. These nonnative species have the potential to harm fish populations, water quality, and water recreation. The 2014 Aquatic Invasive Species Prevention Plan for Morrison County outlines the efforts that Morrison County will undertake to help prevent the spread of harmful AIS within Minnesota.
AIS are an emerging issue within Morrison County. Few waters within the County are infested with invasive species at this time so the County has a unique opportunity to implement some prevention strategies to protect the waters within Morrison County. The Comprehensive Water Plan identifies efforts lake associations and lake improvement districts have made to treat invasives and the importance of that work. As the Water Plan is revised in 2015, AIS will undoubtedly have more of a presence within the plan.
The impetus of this plan has come from the 2014 allotment of the Aquatic Species Prevention Aid. These first steps into AIS prevention include ground level education of likely users of Morrison County’s water resources as well as a bolstering of the ongoing efforts many lake associations/improvement districts have already undertaken, as well as the inspections the Department of Natural Resources provides within Morrison County, and the services provided by the Permitted Lake Service Providers.
