Oregon State University and Lakes Association held the 2023 Cyanobacterial Harmful Algal Bloom Stakeholder Meeting at Oregon State University:  Memorial Union on Friday, March 17, 2023 from 9:00 AM to 4:00 PM.  Live-stream attendance was offered via Zoom.

AGENDA: At this annual meeting, stakeholders typically share information on recent blooms and any changes in regulations and bloom management. Those with new interests in or management responsibilities for HABs in lakes and reservoirs will find this a good meeting to make connections with people in Oregon who are knowledgeable about HABs. 

The morning program covered CyanoHAB monitoring and regulation, as well as reports of CyanoHABs in Oregon during 2022.  The afternoon program covered CyanoHAB research in Oregon or relevant to Oregon.  

Many thanks to the panelists and participants for taking part in the 2023 Oregon CyanoHABs Stakeholder Meeting! If you'd like to review the talks or were not able to attend,  YouTube recordings of the talks and the slides presented are provided below.
