  • Knowledge Gaps Update: In-lake Conditions 2026 (9/21/2026)
    • The HABs Collaborative developed this fact sheet to demonstrate the knowledge gaps regarding limnological processes affecting HABs formation and toxicity and the legislative and funding needs to close these gaps. The fact sheet also includes several research highlights of HABs development, humans health and monitoring in the Great Lakes basin. 
  • Knowledge Gaps Update: Nature-based Solutions to Manage Runoff 2026 (9/21/2026)
    • The HABs Collaborative developed this fact sheet to demonstrate the knowledge gaps regarding watershed runoff management and the legislative and funding needs to close these gaps. The fact sheet also includes several research highlights of nutrient management and monitoring in the Great Lakes basin. 
  • Harmful Algal Blooms Conference Research Summary 2024 (10/22/2024)
    • The HABs Collaborative helped to facilitate sessions at two conferences related to freshwater research in 2024: the International Association for Great Lakes Research (IAGLR) conference and the Association for the Sciences of Limnology and Oceanography (ASLO) annual meeting. This document serves to share the 32 abstracts and contact information from these conference research sessions, as modified for a broader audience (including non-scientists).
  • HABs Science & Policy Workshop Takeaways (10/14/2024)
    • On April 9-10, 2024, the Great Lakes Commission hosted agency officials, scientists, and legislators to chart a way forward on how to reduce and mitigate HABs throughout the Great Lakes-St. Lawrence River basin. This multidisciplinary group discussed nutrient management programs, systems in place to respond to HABs, and potential methods for improving water quality. While this document is not a comprehensive review of the HABs issue, it is intended to provide a summary of workshop discussions.
