Reflections on Serving Transboundary Waters and Communities

IJC admin | 2016/09/06

After five years, the time has come for me to end my service as a US Commissioner for the IJC. “My dream’s dream job” is often how I described this incredible opportunity bestowed upon me by President Obama and the US Senate. I have accepted the position of executive director of the Onondaga County Resource Recovery Agency, charged with managing the solid waste system including waste reduction, composting, recycling, disposal, and energy generation for my local community in Syracuse, New York. I depart the Commission on Labor Day 2016. Read More »

Fish Passageways Key to Solving Nutrient Issues in St. Croix Waterways

IJC admin | 2016/08/16

Improving aquatic connections along the St. Croix River for fish to migrate would be a boon to those populations and the ecosystem at large. That’s according to Dr. Joseph Zydlewski, assistant unit leader of fisheries with the U.S. Geological Survey’s Maine Cooperative Fish and Wildlife Research Unit at the University of Maine in Orono. Zydlewski said he wants to see the St. Croix restored as much as possible to its natural, pre-dammed state. East coast freshwater systems are typically considered “nutrient poor” on their own, he said, so fish migrating in from the sea – such as alewives, shad, salmon and sea lamprey – provide an influx of nutrients as they die and are eaten. To help those inland water systems means understanding how migrating species work together with resident species. Read More »

Osoyoos Lake: The Movie

IJC admin | 2016/08/16

Canadian Prairie Climate Atlas Anticipates Effects on Water Resources


The Prairie Climate Atlas is a new interactive website designed to communicate the implications of climate change to those who live and work in the Canadian Prairie Provinces of Alberta, Saskatchewan and Manitoba. The Atlas is the flagship product of the new Prairie Climate Centre at the University of Winnipeg. Climate models have long indicated that northern, continental climates – including the climate of the Canadian Prairies – are expected to warm much faster than the global average. Read More »

Study Board Discusses Rule Curve Studies with Residents on Rainy and Namakan Lakes

IJC admin | 2016/08/16

The IJC has been directing dam operations to control water levels in Namakan and Rainy Lake since 1949, and one thing has become clear over the years: It’s difficult to come up with water level targets that are optimal for everybody. Adjustments to those targets bring up a variety of questions: How are fish like northern pike and walleye doing? How is wild rice production? What about the resort industry? Read More »

New Vermont Lake Champlain Phosphorus TMDLs Completed

IJC admin | 2016/08/16

A Total Maximum Daily Load, or TMDL, is a pollution budget. In the case of Lake Champlain, the budget refers to a maximum amount of phosphorus, and establishes pollutant reduction targets needed to meet lake water quality goals. Too much phosphorus in many parts of Lake Champlain has been causing algae blooms and related problems for decades. Read More »

Family Ties: Craig Palmer and the Ditch that Inspired a Treaty

IJC admin | 2016/08/16

Adelbert Cazier never set out to start a water conflict between Canada and the United States, particularly not one that prompted the Boundary Waters Treaty and inspired the creation of the IJC. Craig Palmer, Cazier’s great-grandson, recently talked about his family’s role in a border water conflict that led to the creation of the IJC. Palmer was attending the 2016 International Association for Great Lakes Research (IAGLR) conference in Ontario. Read More »

These meetings follow up on consultations held with stakeholders in September 2015 and ongoing input from the Rule Curve Public Advisory Group. Read More »

New International Watershed Initiative Projects Studying Water Quality, Usage and Pollutants

IJC admin | 2016/07/05

Recent studies performed under the IJC’s International Watersheds Initiative (IWI) should provide policymakers and researchers with more information to help make decisions related to fishing, water quality and water withdrawal. A number of projects around the Great Lakes and the St. Mary and Milk Rivers are in the works, focusing on topics from river conditions and algal bloom-causing pollutants to computer model creation.

Microplastics Motivate Cleanups – Find Out More at April 26 Workshop

IJC admin | 2016/04/21

When you think of microplastics, you might think of the microbeads in facial scrubs or toothpaste, but these are actually just one type of microplastics. Another major source is the breaking down of larger pieces of plastic, such as litter, into smaller and smaller pieces. The Great Canadian Shoreline Cleanup and other groups will break down this topic further at a public microplastics workshop at 7 p.m., April 26, at the University of Windsor’s Katzman Lounge in Vanier Hall. IJC commissioners, expert panelists and local activists will be on hand to explain how microplastics are created and how they are impacting the Great Lakes and other local water bodies. Read More »

History and Evolution of the Microbead

IJC admin | 2016/02/22

Considering the ubiquity of plastic in today’s society, it’s difficult to realize how recently the mass production of plastics began. The initial commercial development of thermoplastics such as polyvinyl chloride, low-density polyethylene, polystyrene and polymethyl methacrylate began with the advent of World War II in 1939. Natural rubber was in short supply and extensive research was completed to develop synthetic alternatives. Large-scale production of polyethylenes in the late 1970s reduced their costs dramatically, and new applications were discovered – from cars to personal care products. Read More »
