Zombie Phosphorus: The Long-Term Consequences of Nutrient-Rich Runoff
In lakes throughout the upper Midwest, from giant Lake of the Woods to dozens of smaller lakes in our urban and agricultural landscapes, clean water has not obviously followed pollution reductions. The complex connections between land, water, climate, chemistry, algae, and even fish can conspire to make us pay a high price for past sins. This article from the Field Notes – Stories from the St. Croix Watershed Research Station of the Science Museum of Minnesota examines the role of “legacy” phosphorus in the lake bottom and other factors in recovery of lakes from too much nutrient pollution.

Look for Our Weekly Column on Everything Water
Kelli Saunders, the Foundation’s International Watershed Coordinator has a weekly column in the the Lake of the Woods Enterprise newspaper and online at the Kenora Daily Miner News. This feature series will celebrate the importance of water locally and the great efforts collectively to protect it, will be dedicated to water throughout the summer months – its quality, its governance, its future and how we can all help to preserve it.
Several articles are online now – click the Read more (below) for the links and look to the Lake of the Woods Enterprise newspaper and Kenora Daily Miner News Online for weekly updates!
The Role of Science in the Lake of the Woods-Rainy River Basin
In this article, Bev Clark takes a look at what we’ve learned about Lake of the Woods from some of the key science published in the 2017 special issue of the Journal of Lake and Reservoir Management that was devoted entirely to Lake of the Woods. How has the lake changed? Are we still paying for our past sins from phosphorus pollution built up in the lake bottom? And what role does climate change have?
The Rainy River – A Case Study in Pollution and Recovery
The history of the Rainy River is fascinating. How could it not be with voyageurs and lumberjacks all tangled up in it. The overlooked part of any history lesson, however, is often the timeline of environmental insults that occurred in concert with the industrial revolution and the population of the land and exploitation of its resources.
In this article, Bev Clark explores the history of the pollution and subsequent research and cleanup of the Rainy River as an example that shows what coordinated international efforts engaging the IJC can achieve.
Watershed Forum Highlights Science and Management Actions
On March 13-14, 2019 Lake of the Woods and its watershed went under the microscope at the International Rainy-Lake of the Woods Watershed Forum. Over 160 researchers and members of the public attended the symposium sessions, featuring 34 research presentations covering a wide range of topics, including studies of nutrients and algae, satellite remote sensing tools, water quality models, beavers, fish and more. There were dedicated sessions for the Canadian federal science projects on Lake of the Woods and Science at the IISD-Experimental Lakes Area.
Water Quality & Ecosystem Health Objectives Study – Update
Last fall, the IJC began a study to recommend new water quality and aquatic ecosystem health objectives and alert levels for our boundary waters like the Rainy River and Lake of the Woods. Objectives require international agreement (e.g., like the phosphorus objectives agreed to by Canada and the United States for the Great Lakes). Alert levels are trigger levels for the IJC to warn governments of potential problems, for substances or issues where there are no internationally agreed upon objectives.
ECCC Science Update: Measuring Algae Blooms from Space
The satellite view from space is compelling of blue green algae blooms covering Lake of the Woods. Dr. Caren Binding of ECCC is harnessing these images for near real-time tracking of algae blooms and to develop indices of bloom severity, intensity, extent and duration. These indices may prove to be very useful in monitoring and measuring the effectiveness of efforts to cutting phosphorus to reduce harmful algae blooms.
Profiles of this project and the other science projects underway by Environment and Climate Change Canada on Lake of the Woods are available at the Foundation’s website: www.lowwsf.com/eccc-science.
Canada and the U.S.A Appoint New IJC Commissioners
At a meeting of the International Joint Commission (IJC), Canadian Commissioners Pierre Béland, Merrell-Ann Phare and F. Henry Lickers made a solemn declaration to faithfully and impartially perform the duties assigned under the Boundary Waters Treaty. Also announced was that the appointments of Jane Corwin as US Section chair, and Robert Sisson and Lance Yohe as US Section Commissioners has been confirmed by the US Senate.

Minnesota’s Plan to Cut Phosphorus: Update
Minnesota’s plan to cut phosphorus entering Lake of the Woods was submitted to US EPA for review last fall as the first step in the approval process. The MPCA is currently responding to the federal review, prior to taking the plan forward through a formal public consultation period, anticipated for later this summer. We’ll keep you informed via the Foundation’s website and e-news about progress on the Minnesota plan and opportunities for public input.
Watch for word coming out for public meetings in Minnesota (International Falls, Baudette and Warroad) and a WebEx online conference for folks in Canada and others who cannot attend in person.
