Remembering Mark Heggli

We are deeply saddened to announce the passing of Mark Heggli, who left us on the 27th of September. Mark’s accomplishments as a Meteorologist and Hydrologist have been impactful in this field and he will be remembered for fulfilling a very distinguished career. He served as a Research Meteorologist for the United States Bureau of Reclamation from 1978 to 1988 and then worked for the California Department of Water Resources. From there, in 2002 Mark developed his own consulting company, Innovative Hydrology, Inc., where they have worked in over 40 countries on flood warning and hydrology projects. Additionally, he received the official President Award for his outstanding service as the AUG President from 1998 to 2000, during which he contributed greatly to the 2001 NHWC Conference and has made keynote presentations at past conferences. As we mourn this profound loss, we cherish the memories of the time we shared, and we will honor his contributions. Our thoughts and prayers are with his family and friends during this difficult time.
