2020 Partner Programs: Accepting Proposals through November 29!

CIGLR is accepting proposals from Regional Consortium members for a suite of programs including Postdoctoral Fellowships, Graduate Research Fellowships, Summer Fellowships, Summits and Working Groups, Rapid Funds, and ECO Awards. These programs aim to build collaborative partnerships through career development opportunities, visionary science, and impactful outreach. Please visit the full program announcements for descriptions, eligibility, and application information. Contact CIGLR Program Manager Mary Ogdahl ( with questions. READ MORE

University of Michigan Master’s Students Work to Improve Harmful Algal Bloom Forecasts in Saginaw Bay, Lake Huron and Western Lake Erie

The progress made toward understanding, monitoring, and forecasting HABs in western Lake Erie has motivated the initiation of a similar program for Saginaw Bay, Lake Huron. However, it is unknown whether lessons from Lake Erie are relevant to Saginaw Bay as the ecological and social settings differ between the two systems. This year, four University of Michigan master’s students from the School for Environment and Sustainability chose to focus on research questions that address important knowledge gaps between these two systems and their HABs problems. The student team is working toward increasing the accuracy of the HAB Tracker forecast tool and its usability within public water systems. READ MORE

What Determines Public Support for Water Quality Regulations to Mitigate Agricultural Runoff?

Excess nutrients threaten the health of the Great Lakes and the communities that surround them. For many freshwater systems exhibiting symptoms of excess nutrients, such as algal blooms, mitigating runoff from agricultural areas is necessary to improve water quality. However, developing socially-acceptable policies to better manage nutrients on the land has been a challenge, and has slowed progress toward healthier lakes. A policy debate is currently unfolding in Ohio, focused on whether the state government should impose nutrient reduction regulations on agricultural producers in an attempt to curb harmful algal blooms in Lake Erie. READ MORE


Can Asian Carp Survive in Lake Michigan?

The invasion of several notorious invasive species, such as the sea lamprey and zebra mussels, has transformed the ecological landscape of the Great Lakes. The prevention of future invasions has become the strategic priority of invasive species management and has motivated research that identifies which species pose the greatest threat to the Great Lakes. Of the many species being monitored by scientists, perhaps none are more concerning than bighead and silver carp (collectively referred to as bigheaded carp), two plankton-feeding species of Asian carp. The close proximity of the bigheaded carp population to Lake Michigan has elevated concerns about the impact they could have on the Great Lakes food web, which supports a $7 billion recreational fishery, prompting the question: does Lake Michigan have enough food for Asian carp to thrive?  READ MORE

Using the NOAA National Water Model to Guide Fertilizer Application and Improve Water Quality

Many lakes and streams in the Great Lakes region and upper Midwest have water quality issues related to nutrient runoff from the land, some of which can be prevented by carefully timed decisions by fertilizer applicators. When fertilizer is applied just before a heavy rainfall, nutrients intended to enrich the soil can end up in the water instead. Farmers lose revenue as their fertilizers wash away and crop yields suffer, while local and downstream waterways experience serious water quality consequences. A collaborative effort spearheaded by the NOAA National Weather Service has produced a decision support tool called the Runoff Risk Advisory Forecast (RRAF) to help guide the timing of fertilizer application based on real-time weather forecasts and soil moisture conditions.
