The Lake Shamineau Improvement District is planning three hand pulling sessions of invasive Eurasian watermillfoil June to August 2017. If a property owner does NOT want milfoil removed adjacent to their lakeshore property, they must submit a waiver request: 2017 Milfoil Removal Waiver Request
The previous survey was done in August 2014. Here is the full report: ShamineauEWMsurvey2014
The value of aquatic plants
Aquatic plants are a natural part of most lake communities and provide many benefits to fish, wildlife, and people. In lakes, life depends–directly or indirectly–on water plants. They are the primary producers in the aquatic food chain, converting the basic chemical nutrients in the water and soil into plant matter, which becomes food for all other life.
Aquatic plants serve many important functions, including:
- Provide fish food
- Offer fish shelter
- Improve water clarity and quality
- Protect shorelines and lake bottoms
- Provide food and shelter for waterfowl
- Improve aesthetics
- Provide economic value
Permit required for alteration of aquatic vegetation
- Any control of emergent vegetation, such as cattails, and the use of pesticides in public waters does require a DNR aquatic plant management permit. Aquatic plants such as cattail, bulrush, water lilies, and other aquatic vegetation are important because they reduce wave action (thereby reducing the threat of shoreline erosion), provide fish and wildlife habitat, buffer shorelines from pollutants, and provide other environmental benefits. DNR aquatic plant management permits are issued through the DNR Regional Fisheries Offices. The rules governing the destruction of aquatic vegetation are found in Minnesota Rules – Chapter 6280.

Bog permit available for Lake Shamineau Association Members
Al Doree has obtained a 2017 Bog permit from the Department of Natural Resources (DNR) that allows members of the Lake Shamineau Association to move or remove floating clumps of cattails. Collecting, transplanting or removing aquatic vegetation requires a permit from the DNR Fisheries Aquatic Plant Management Program. Because of their value to a lake’s ecosystem, aquatic plants growing in public waters are considered state property under Minnesota law, and their removal is regulated.
Pieces of cattail bog sometimes break away and float out into the lake. These can become hazardous to boat traffic. Large bog sections should be staked back to a cattail area to preserve the habitat for fish and wildlife and protect shoreland from erosion when possible. With our permit, Lake Association members are allowed to remove smaller (less than 6′ X 6′) floating sections. They can be dragged up on shore and removed or you could choose to move them somewhere along your shoreline to enhance your buffer area.
Distribution of Aquatic Plants in Lake Shamineau (2005)
The Minnesota Department of Natural Resources did a complete aquatic plant vegetation survery of Lake Shamineau in 2005.
Number and types of plants recorded
A total of 30 native aquatic plant species were recorded in Shamineau Lake including five emergent, four floating-leaved, one free-floating and 20 submerged plants. One non-native submerged plant, curly-leaf pondweed (Potamogeton crispus) was identified in the lake.
Distribution of plants by water depth
Plants were found to a maximum depth of 20 feet in Shamineau Lake and within the vegetated zone (shore to 20 feet), 73 percent of sample sites contained vegetation. Plant occurrence was greatest in depths from shore to 15 feet, where vegetation was found in more than 80 percent of the sample sites.
The highest number of plant species was found in shallow water, from shore to a depth of five feet. Emergent, floating-leaved and free-floating plants were restricted to water depths less than ten feet. Submerged plants were found to a maximum depth of 20 feet but only ten species occurred in depths greater than 15 feet. Curly-leaf pondweed was found at all water depths between shore and 20 feet.
The number of plant species found at individual sites ranged from zero to nine with a mean of two species per site. Shallow, protected bays usually contained sites with the highest number of species while most off-shore deeper water sites had only one to three species.
