NALMS at 40: Leveraging Experience to Manage Diverse Lakes, Landscapes and People

40th International Symposium of the North American Lake Management Society

November 16–20, 2020 – Minneapolis, Minnesota

NALMS Conference Committee members are monitoring information about how the coronavirus might affect future gatherings and travel. Should plans for the 2020 NALMS Symposium change, we will provide updates here and on the Symposium landing page. Meanwhile, we urge potential presenters to submit abstracts by the deadline, thereby allowing Planning Committee members to provide timely information regarding the technical content of the Symposium.

The Dakota (Sioux) homeland Mni Sóta Maķoce means “land where the waters reflect the clouds.” Nicknamed “Land of 10,000 Lakes,” Minnesota really has almost 12,000 inland basins covering at least 10 acres, but across the state, they are mostly rural and rather diverse. Deep, oligotrophic waters are typical in northeastern boreal forests near Superior, the world’s largest areal, freshwater lake. Shallow, hypereutrophic lakes predominate in southwestern agricultural plains.

With about 30 lakes and 700,000 residents within 64 square miles, the twin cities of Minneapolis and St. Paul reflect some of the challenges of managing Minnesota’s urban landscapes. Generations of Dakota (Sioux) called the area’s largest and deepest lake Bdé Makhá Ská, but since the 1820s, it had been called Lake Calhoun. In 2018, the federal government officially restored the name, but the Minnesota Court of Appeals in 2019 reversed the state’s official designation of the indigenous name. Positioned in this nexus between Minnesota’s rural-urban diversities and past-future legacies, Minneapolis hosts the 2020 symposium that focuses on NALMS’ 40 years of experience. The Program Committee hopes this symposium not only reflects with 20/20 hindsight, but also predicts with 20/20 foresight!


Prospective Program

There will be technical workshops all day Monday, November 16. Beginning Tuesday, November 17, presentations will be organized into themed tracks and sessions.

General Presentation Information

  • We will prioritize oral presentations that describe completed or well-advanced studies with lab and/or field data. We encourage presentations that also project future challenges and advances in lake management. However, we discourage presentations that solely describe future projects, or which do not include data. We will make special arrangements for exhibitor presentations and/or that consist primarily of vendor information.
  • NALMS does not endorse specific products or services. Thus, any poster or presentation must include disclosure(s) of any and all relevant relationship(s) with: i) any and all corporations or ii) commercial product(s), iii) method(s), and iv) trade or brand name(s).

  • We require PowerPoint files for all oral presentations. We will provide laptop computers and LCD projectors. Presentation computers will not have internet access or sound output available.
  • We discourage use of embedded video and audio files.
  • Oral presentations will be allotted 20 minutes, including time for questions.
  • We encourage abstract submissions for poster sessions. All posters will be displayed throughout the symposium in landscape format. Display areas will accommodate posters up to 4’ × 8’ (1.2 m × 2.4 m).
  • Students making oral or poster presentations as primary authors will be considered for student awards.
  • All presenters of accepted abstracts must register for the symposium. NALMS must receive registration and payment no later than September 4, 2020 to ensure inclusion in the symposium program. NALMS does not waive registration fees for presenters.

  • We accept abstracts only via the NALMS website ( Abstracts must include the following information, as specified.
    • Title: Summarize accurately the subject of the presentation.
    • Authors: Provide names and affiliations of all authors. NOTE: Indicate if the primary author is a student so the presentation may be considered for student awards.
    • Text: State the purpose, significant findings, and main conclusions of the work. Avoid statements like “Results will be presented“ and “Implications will be discussed.” Provide a concise summary of results and implications. Abstracts must not exceed 250 words; those in excess of 250 words may be truncated. Abstracts selected for either oral or poster presentations will be available to conference attendees.
    • Format: Indicate your presentation preference (oral, poster, either or both).
