About the 4th District

Although Michiganโ€™s 4th Congressional District does not directly touch any of the Great Lakes, it still has a close connection with โ€“ and is affected by โ€“ the Great Lakes that lie to the east and west. Lake-effect snow impacts communities in the northwest portion of...
Harmful Algal Blooms (HABs) & Hypoxia

Harmful Algal Blooms (HABs) & Hypoxia

More than 48 million people in the U.S. and Canada rely on the Great Lakes as a source of clean drinking water. However, water quality problems caused by excess nutrients are putting some Great Lakes communities at risk. Harmful algal blooms (HABs) can produce toxins that threaten human health. Hypoxia, or extremely low oxygen, can cause water to be corrosive, discolored, and contain manganese, a heavy metal that is toxic to humans at high levels. With our partners at the NOAA Great Lakes Environmental Research Laboratory, CIGLR is engaging public utility managers to co-design HABs and hypoxia forecasts that provide the advance warning needed to ensure the delivery of safe and healthy water to Great Lakes communities.

Agricultural Decision Support

Agricultural Decision Support

When agricultural fertilizers are applied just before a heavy rainfall they can wash away into local waterways, costing farmers money and causing serious water quality problems. A collaborative effort led by the NOAA National Weather Service (NWS) has produced a decision support tool to help farmers determine the best time to apply fertilizers based on weather forecasts and soil moisture conditions. CIGLR and our partners are working with NWS to improve the accuracy of the Runoff Risk Advisory Forecast and evaluate its effectiveness for improving water quality, with the goal of providing farmers with an easy-to-implement best management practice that maximizes profit while protecting water quality.

Lake Effect Snow & Ice

Lake Effect Snow & Ice

Winter weather brings challenges for commerce, risks for human safety, and opportunities for recreation to the Great Lakes region. Accurate forecasts of lake effect snow and lake ice conditions are important for community preparedness and industry decision-making, but have been difficult to develop. With our partners including the NOAA Great Lakes Environmental Research Laboratory and National Weather Service (NWS), CIGLR is developing models to improve lake effect snow forecasts, ice predictions, and visibility forecasts. We engage with Great Lakes mariners to help us co-design the products that they need for safe commerce, transportation, and search-and-rescue efforts. LEARN MORE
