Ann Arbor, Michigan/Chicago, Illinois — A report released today on Great Lakes water use demonstrates the region’s ongoing commitment to coordinated, science-based management of the world’s largest freshwater system. The 2024 Annual Report of the Great Lakes Regional Water Use Database shows that water withdrawals in the basin remained stable, with the vast majority of withdrawn water returned to the Great Lakes St. Lawrence River Basin.

Overall, the basin gained a total of 345 million gallons of water per day in 2024; by comparison, the basin lost 550 million gallons per day in 2023. This change is primarily due to an increase in the amount of water diverted from the Hudson Bay watershed into the Lake Superior basin through the Long Lac and Ogoki diversions in northern Ontario.

The report found that 35.7 billion gallons of water per day were withdrawn from the Great Lakes basin in 2024, representing a less than 1% increase from 2023. Just under 5% of the total reported water withdrawn was consumed or otherwise lost from the basin. Thermoelectric power production (once-through cooling), public water supply, and industrial use were the primary water use sectors.

The report’s findings were shared at the December meeting of the Great Lakes St. Lawrence River Basin Water Resources Council and the Great Lakes St. Lawrence River Water Resources Regional Body. Since 1988, the eight U.S. states and two Canadian provinces have reported water use data to the Great Lakes Commission, which compiles and summarizes these datasets into an annual report. This report meets requirements of the Great Lakes Compact and Agreement, and strengthens shared stewardship of the basin’s waters by improving access to consistent information on how water is withdrawn, used, and conserved across the region.

“This report gives the Great Lakes states and provinces the information needed to better manage water use in the largest surface freshwater system in the world, but also serves as an example of how interstate compact agencies can leverage each other’s strengths and share expertise to the benefit of everyone in the basin,” said Great Lakes Commission Chair Timothy Bruno, Great Lakes Program Coordinator at the Pennsylvania Department of Environmental Protection.

“The value of shared regional water use reporting is more evident than ever,” said Loren Wobig, chair of the Regional Body and Compact Council. “This reporting is an important tool in supporting the regional water resources management that is so vital to future development in the Great Lakes region.”

“For more than 15 years, the Compact and Agreement have provided a model for regional cooperation and responsible water management,” said Peter Johnson, deputy director of the Conference of Great Lakes St. Lawrence Governors & Premiers (GSGP). “This annual reporting initiative is central to advancing sound decision-making, sustainable economic development, and long-term protection of our region’s waters.”

The Great Lakes St. Lawrence River Basin Water Resources Compact Council is comprised of the Governors of the eight Great Lakes States and is responsible for implementing the Great Lakes–St. Lawrence River Basin Water Resources Compact in the United States. The Compact, which is both State and U.S. Federal law, protects the largest freshwater body on earth.

The Great Lakes St. Lawrence River Water Resources Regional Body consists of the Governors of the eight Great Lakes States and the Premiers of Ontario and Québec. Formed under the Great Lakes–St. Lawrence River Basin Sustainable Water Resources Agreement, the Regional Body promotes coordinated review, information sharing, and cooperative action in managing Great Lakes water resources across the international border.

Ann Arbor, Michigan – Nearly $315,000 will be awarded to support local organizations in controlling nonnative Phragmites australis, one of the most aggressive plant species invading the Great Lakes basin and North America. Grantees will implement certain combinations of management actions for Phragmites, and the Phragmites Adaptive Management Framework (PAMF) will use the data gathered to improve guidance on management practices that are most likely to be effective.

Phragmites is currently managed using a suite of approaches, including herbicide, cutting/crushing, flooding, and burning. These actions are resource intensive and differ in effectiveness due to site-specific conditions and variations in implementation. PAMF is a predictive model, developed by the Great Lakes Phragmites Collaborative, that uses participant data to continually ‘learn’ more about which management techniques are working against Phragmites in certain conditions and which are not. In turn, the PAMF model predicts optimal guidance for each site. Data provided to PAMF by grantees will reduce the uncertainty surrounding management outcomes, increase the model’s predictive power, and improve best management practices.

2025 is the second year that PAMF Active Adaptive Management Program grants are available for Phragmites management in Great Lakes states. In the first year of the program, AAMP recipients from 17 organizations contributed 70 management units totaling over 130 acres. The grant program contributed data to six combinations lacking data in the PAMF model, three of which had no prior data.

Twenty-one grants have been awarded in 2025:

The Great Lakes Phragmites Collaborative (GLPC) is a regional partnership led jointly by the Great Lakes Commission and U.S. Geological Survey to foster more coordinated, efficient and strategic approaches to Phragmites management and ecosystem restoration. Funding for the PAMF Active Adaptive Management Program is provided by the Great Lakes Restoration Initiative (GLRI).

Ann Arbor, Mich. – The Great Lakes Commission (GLC) will award more than $1.76 million in grants to local groups to reduce the runoff of pollutants such as sediment and nutrients from entering the Great Lakes and their tributaries. Since 2016, projects funded by the Great Lakes Sediment and Nutrient Reduction Program have protected the Great Lakes through the prevention of nearly 200,000 pounds of phosphorus, 400,000 tons of sediment and millions of gallons of stormwater from leaving the landscape.

“Local communities are critical partners in improving the ecological and economic health of the Great Lakes,” Timothy Bruno, chair of the Great Lakes Commission and Great Lakes Program Coordinator at the Pennsylvania Department of Environmental Protection. “The Great Lakes Commission congratulates the 2025 grantees and look forward to their contribution to a resilient Great Lakes basin.”

With a focus on phosphorus and sediment reduction, the Great Lakes Sediment and Nutrient Reduction Program provides competitive grants to local and state governments, Indigenous Nations, and nonprofit organizations to install erosion and nutrient control practices in the Great Lakes basin each year. Funded projects often include innovative and unique practices not typically funded by other federal cost-share programs.

The 2025 projects continue to promote two approaches: long-term sediment and nutrient management through engagement with the agricultural community and streambank restoration.  The following grants have been awarded:

Since 2010, the U.S. Department of Agriculture – Natural Resources Conservation Service has provided funding for the Great Lakes Sediment and Nutrient Reduction Program under the Great Lakes Restoration Initiative (GLRI). In that time, the GLRI has provided over $4 billion to fund more than 8,000 projects across the Great Lakes region, which protect freshwater resources by restoring wetlands, preventing the spread of invasive species, and reducing sediment and nutrients.

Duluth, Minnesota – At its Annual Meeting, held this week on the shores of Lake Superior in Duluth, Minnesota, the Great Lakes Commission (GLC) passed resolutions calling for advancement of non-potable water reuse and coordinated resource management in the development of AI and computing infrastructure, as well as prevention of plastic pollution and harmonization of stormwater management in the Great Lakes and St. Lawrence River region.

“The economy of the Great Lakes region is supported by access to water — from industry to agriculture and outdoor recreation to shipping,” said GLC Executive Director Erika Jensen. “Our commissioners have noted a growing need to understand the impacts that new technologies will have on the Great Lakes and the roles that water recycling and reuse can play.”

At the meeting, the GLC also elected new leadership: Chair Timothy Bruno, Great Lakes Program Coordinator at the Pennsylvania Department of Environmental Protection, and Vice Chair James Jennings, Director of the Illinois Environmental Protection Agency.

“I’m honored for the opportunity to serve as chair of the Great Lakes Commission,” said Chair Bruno. “This critical agency brings the region together to work on issues that no single community, state, province, or nation can tackle alone. On behalf of the GLC, I’d also like to extend our gratitude to immediate past chair Mary Mertz, director of the Ohio Department of Natural Resources, for her incredible leadership over her two terms as chair of the agency.”

The Annual Meeting featured remarks from Duluth Mayor Roger Reinert and journalist Peter Annin, author of Purified: How Recycled Sewage Is Transforming Our Water and The Great Lakes Water Wars and executive director of the Burke Center for Ecosystem Research. Attendees also heard from expert panels on microplastics, harmful algal blooms, and water reuse and students participating in environmental programs at Duluth Public Schools. On Wednesday evening, attendees celebrated the 70^th anniversary of the GLC, which was established in 1955 by the Great Lakes Basin Compact. The Compact was ratified by the Great Lakes state legislatures and granted consent by the U.S Congress in 1968.

In advance of the meeting, GLC leadership planted two trees on the Superior Hiking Trail. As a founding member of the Great Lakes St. Lawrence Trees and Green Events initiatives, the GLC has committed to using sustainable practices at its meetings and supporting the initiative’s goal of planting 250 million trees in the Great Lakes basin by 2033. The GLC also hosted a tour of the St. Louis River Estuary on the Duluth River Train; representatives of the Minnesota and Wisconsin Departments of Natural Resources, the Minnesota Pollution Control Agency, and the Fond du Lac Band of Lake Superior Chippewa outlined remediation and restoration work underway in the estuary. Additionally, the GLC hosted a screening of the film Ripples of Plastic, which explores the unseen impacts of plastic pollution in the Great Lakes, including contamination, microplastics, and human health effects, and a conversation with the filmmaker.

The GLC will next convene in Washington, D.C. for its Semiannual Meeting and Great Lakes Day on March 3-5, 2026. More information will be available on the GLC’s website in advance of the meeting.

Ann Arbor, Michigan – Organizations across the region will come together to educate the public about aquatic invasive species (AIS) during the seventh annual Great Lakes AIS Landing Blitz, to be held June 30 through July 13, 2025. Volunteers will demonstrate to boaters how to prevent the spread of AIS, how to identify AIS, and how to report AIS, which are recognized as one of the most significant threats to the ecological and economic health of the Great Lakes. This annual event is coordinated through an international partnership of Indigenous, federal, state, and provincial agencies with the support of the Great Lakes Commission (GLC) and other partner organizations.

“The Great Lakes Commission is proud to continue coordinating the Great Lakes AIS Landing Blitz with our partners,” said GLC Executive Director Erika Jensen. “Invasive species threaten native species and the regional economy. Fish and wildlife cross jurisdictional boundaries, so we all need to work together to avoid spreading harmful species from one water body to another.”

For the fourth year, the Great Lakes Commission has also awarded more than $105,000 in grants to local organizations to conduct outreach to boaters this summer. This funding will be used by grantees to host local Landing Blitz events, expanding the overall reach of the initiative and supporting strategic education and outreach targeted to the recreational activities pathway of AIS introduction and spread.

Thirteen grants were awarded:

Funding for the Great Lakes AIS Landing Blitz is provided by the Great Lakes Restoration Initiative through a grant agreement between the Great Lakes Commission and the U.S. Fish and Wildlife Service.

Ann Arbor, Michigan – The Great Lakes Commission (GLC) today released its 2025 agenda for the Great Lakes. It calls for continued strategic investment in the lakes, which hold 95% of America’s fresh surface water and provide drinking water for more than 47 million people.

“Restoring the Great Lakes means protecting drinking water for millions, as well as growing an $81 billion regional recreational economy and a nearly $51 billion maritime system,” said GLC chair Mary Mertz, director of the Ohio Department of Natural Resources. “The Great Lakes Commission urges our federal partners to continue their investment in the Great Lakes Restoration Initiative, and other programs that improve the region’s economy and environment, as every $1 spent restoring the lakes generates more than $3 in economic activity for the country.”

In 2025, the GLC urges Congress and the administration to: fully fund the Great Lakes Restoration Initiative; fund the GLC to fulfill its unique role in the region; provide the cleanest and safest drinking water in the world; unlock the economic potential of the Great Lakes Navigation System; eliminate harmful algal blooms; defend against invasive species; and build a resilient Great Lakes basin.

The agenda is being shared in advance of next week’s Great Lakes Day, an annual event that brings together regional leaders and members of Congress who play a critical role in shaping Great Lakes policies. Great Lakes Day will be held in-person in Washington, D.C., following the 2025 Great Lakes Commission Semiannual Meeting. The GLC and Northeast-Midwest Institute organize Great Lakes Day annually to bring together the states, members of Congress and the federal government to raise awareness of Great Lakes issues.

Rochester, New York – At its Annual Meeting, held last week on the shores of Lake Ontario in Rochester, New York, the Great Lakes Commission (GLC) passed resolutions calling for reauthorization of the Great Lakes Restoration Initiative and stronger protections against the introduction of invasive species.

“The Great Lakes Commission urges both federal governments to better protect the Great Lakes by taking action to restrict the import of high-risk species,” said GLC Chair Mary Mertz, director of the Ohio Department of Natural Resources. “Once established in the lakes, these species are extremely difficult to eradicate and costly to control. Additionally, we call on the U.S. Congress to pass the Great Lakes Restoration Initiative Act of 2024, which would reauthorize this incredibly successful program through FY 2031. Since 2010, the GLRI has provided more than $4 billion to fund more than 8,100 projects across the Great Lakes region which protect our freshwater resources.”

The Annual Meeting featured remarks from representatives of U.S. EPA Regions 2 and 5, U.S. Sen. Kirsten Gillibrand, and Rochester Mayor Malik Evans. Great Lakes Commissioners also heard from expert panels on critical issues facing the lakes, including community watershed restoration, coastal resilience, and engaging youth in environmental stewardship.

At the meeting, the GLC re-elected its leadership: Chair Mertz, and Vice Chair Timothy Bruno, Great Lakes Program Coordinator, Interstate Water Resources Management, at the Pennsylvania Department of Environmental Protection. In advance of the meeting, GLC leadership planted two red maple trees at the Rochester Museum & Science Center. As a founding member of the Great Lakes St. Lawrence Trees and Green Events initiatives, the GLC has committed to using sustainable practices at its meetings and supporting the initiative’s goal of planting 250 million trees in the Great Lakes basin by 2033.

The GLC will next convene in Washington, D.C. for its Semiannual Meeting and Great Lakes Day on March 4-6, 2025. More information will be available on www.glc.org in advance of the meeting.

Ann Arbor, Mich. –​ The Great Lakes Commission (GLC) announced today that it will award more than $1.45 million in grants through the Great Lakes Sediment and Nutrient Reduction Program to reduce the runoff of pollutants such as sediment and nutrients from entering into the Great Lakes and their tributaries.

“For more than three decades, grants under our Great Lakes Sediment and Nutrient Reduction Program have supported local efforts to reduce sediment and nutrient pollution of our Great Lakes,” Timothy Bruno, vice chair of the GLC and Great Lakes Program Coordinator, Interstate Water Resources Management, at the Pennsylvania Department of Environmental Protection. “Community efforts are critical to the lakes’ health. The Great Lakes Commission congratulates the 2024 grantees of this longstanding program and looks forward to their projects’ contribution to a healthier and more resilient Great Lakes basin.”

Each year, the Great Lakes Sediment and Nutrient Reduction Program provides competitive grants to local and state governments, Indigenous Nations, and nonprofit organizations to install erosion and nutrient control practices in the Great Lakes basin, including innovative and unique practices not typically funded by other federal cost-share programs. Since 2016, projects funded by this program have prevented more than 173,000 pounds of phosphorus and more than 337,000 tons of sediment from reaching the Great Lakes.

The 2024 projects continue to promote two approaches: long-term sediment and nutrient management through engagement with the agricultural community and streambank restoration.  The following grants have been awarded:

Since 2010, the U.S. Department of Agriculture – Natural Resources Conservation Service has provided funding for the Great Lakes Sediment and Nutrient Reduction Program under the Great Lakes Restoration Initiative (GLRI). In that time, the GLRI has provided more than $4.1 billion to fund more than 8,100 projects across the Great Lakes region which protect freshwater resources by restoring wetlands, preventing the spread of invasive species, and reducing sediment and nutrients.

Ann Arbor, Mich. –​ The Phragmites Adaptive Management Framework (PAMF) is initiating the first cycle of a new program that will improve Phragmites management across the Great Lakes basin and beyond. Through the PAMF Active Adaptive Management Program (AAMP), more than $239,000 will be awarded to support local organizations in implementing certain combinations of management actions on which PAMF is lacking data. PAMF will use the information gathered by participants to improve its guidance on management practices that are most likely to be effective in controlling invasive Phragmites.

Currently, invasive Phragmites are managed using a suite of approaches, including herbicide, cutting/crushing, flooding and burning. These actions are resource intensive and differ in effectiveness due to site-specific conditions and variations in implementation. The PAMF program utilizes a predictive model that incorporates participant data to continually ‘learn’ more about which management techniques are working against Phragmites in certain conditions and which are not. In turn, the PAMF model predicts optimal guidance for each site based on the most up-to-date data. This process repeats annually to optimize outcomes. Data provided to PAMF by the AAMP grantees will reduce the uncertainty surrounding management outcomes, increase the models predictive power, and improve regional best management practices.

“Nonnative Phragmites australis is one of the most aggressive plant species invading North America and is already well established in the Great Lakes basin,” said Timothy Bruno, vice chair of the Great Lakes Commission and Great Lakes Program Coordinator, Interstate Water Resources Management, at the Pennsylvania Department of Environmental Protection. The GLC provides backbone and administrative support to PAMF. “Its spread has negative impacts on wildlife, water levels and drainage, recreation and tourism and even public safety. The Active Adaptive Management Program will help expand and improve the management of Phragmites across our region.”

2024 is the first of at least two years that AAMP grants will be available for Phragmites management in Great Lakes states. Eligible grantees include tribal or U.S.-based local units of government, lake associations, watershed protection groups, nonprofit 501(c)(3) organizations, colleges, and conservation groups.

Seventeen grants have been awarded so far in 2024:

Funding for the PAMF Active Adaptive Management Program is provided by the Great Lakes Restoration Initiative (GLRI) through a grant agreement between the Great Lakes Commission and the U.S. Geological Survey. For more information on AAMP, visit the program’s website.

Ann Arbor, Mich. – The Great Lakes Commission (GLC) announced today that it has released an updated Great Lakes Water Use Database website that is more secure and will make it easier for the public to access water use data. Upgrades to the site include: a streamlined, more intuitive process for water use data managers to report their jurisdictions’ data and metadata; an improved public-facing “create your own query” tool that will allow users to create charts based on their specific data selections; and enhanced security features to better protect data before it is published.

“More than 30 million people in the basin rely on the Great Lakes for drinking water, jobs, industry and more,” said Loren Wobig, Great Lakes Commissioner and Illinois Governor JB Pritzker’s alternate on the Great Lakes-St. Lawrence River Basin Water Resources Council (Compact Council) and Designee on the Great Lakes-St. Lawrence River Water Resources Regional Body (Regional Body). “This new website will help regional decision-makers better manage our water resources responsibly for all the basin’s residents.”

“One of the key goals of the Great Lakes-St. Lawrence water management compact and agreement was facilitating the exchange of data and strengthening the scientific information upon which decisions are made,” said Peter Johnson, Deputy Director of the Great Lakes St. Lawrence Governors and Premiers (GSGP), the organization that serves as secretariat to the Compact Council and Regional Body. “This upgrade to the water use database is an important step in further advancing the Governors’ and Premiers’ water management priorities.”

For nearly 40 years, as part of the historic water agreements, the eight states and two provinces in the Great Lakes-St. Lawrence River basin have provided water use data to the regional water use database. The GLC compiles and summarizes these datasets into an annual report that is submitted to the Compact Council and Regional Body, which manage the agreements to sustainably manage Great Lakes water.

Ann Arbor, Mich. – The Great Lakes Commission (GLC) today applauded the states of Illinois and Michigan and the U.S. Army Corps of Engineers for signing a project partnership agreement (PPA) for the Brandon Road Interbasin Project. This project, which was originally authorized in 2020, is a key component of the region’s longstanding efforts to protect the Great Lakes from invasive carp.

“Preventing invasive carp from entering the Great Lakes is a team effort, and the Great Lakes community is stepping up to meet the moment,” said Erika Jensen, executive director of the GLC. “Signing the Brandon Road PPA is a critical step in keeping invasive carp out of the Great Lakes. Illinois, Michigan, and the Army Corps of Engineers all deserve enormous credit for the years-long effort to address this threat. The GLC is also especially grateful for our Great Lakes congressional delegation, who have worked tirelessly to secure federal funding and policy changes necessary to move forward with construction.”

The GLC has worked for over 30 years on efforts to prevent the introduction and spread of aquatic invasive species, including support for the Brandon Road Interbasin Project. Since 2019, the GLC has convened the Brandon Road States and Provinces Forum, which has served as an important venue for information-sharing and problem-solving.

The Brandon Road Interbasin Project is located at the Brandon Road Lock and Dam on the Des Plaines River in Joliet, Illinois. This project will include installation of technologies that will prevent invasive bighead, black, and silver carp from entering Lake Michigan through the Chicago Area Waterway System. Invasive carp present a significant threat to the Great Lakes, including their impacts on ecosystems, fisheries, and recreation, all of which help to drive the Great Lakes regional economy.
