Valuing Water: Economics, Ecology, & Culture

41st International Symposium of the North American Lake Management Society

November 15–18, 2021 – Oklahoma City, Oklahoma

We are planning the 2021 symposium as our first chance to get back to face-to-face meetings. However, we understand that not everyone will be able to attend in person, and so will also be coordinating limited live virtual opportunities during the conference as well as asynchronous programming. Abstract submitters will be asked as to their intended participation and given the choice of “in-person” or “virtual only.” All presenters will be encouraged to submit their presentation pre- or post-conference for online asynchronous viewing.

The Oklahoma Clean Lakes and Watersheds Association welcomes you back to Oklahoma City for the NALMS 41st International Symposium. Downtown Oklahoma City is a beautiful place to be in the fall with amazing weather! Explore The Modern Frontier! From our parks, museums, and entertainment districts as well as a fantastic selection of restaurants, there’s something for everyone to enjoy during your stay in OKC.

Don’t miss the opportunity to network with some of the most knowledgeable leaders in lake and watershed information and technology. The conference will consist of multiple panels and discussions focused on the value of water for economics, ecology, and culture.


Prospective Program

There will be technical workshops all day Monday, November 15. Beginning Tuesday, November 16, three days of presentations will be organized into themed tracks and sessions. We encourage oral and poster presentations on any aspect of lake and reservoir management, but especially invite valuable insights on the following:

  • Harmful Algal Blooms

  • 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.
