Event Details
A free, informal speaker series about the St. Louis River Estuary in Duluth-Superior
Two speakers will offer virtual talks at 7 p.m. on Wednesday, Oct. 14, via Zoom. Brandon Krumwiede, Great Lakes geospatial coordinator with NOAA’s Office for Coastal Management, will present, “Water Level Change Impacts in the St. Louis River Estuary.” Over the past several years, water level changes from near-record lows to near-record highs have altered the shorelines along Lake Superior and the estuary. Krumwiede’s presentation will provide an overview of the interplay between water levels and physical changes seen along the shorelines.
Hannah Burgstaler, freshwater fellow at the Lake Superior National Estuarine Research Reserve, will present, “St. Louis River Estuary Water Level and Canada Geese Population Effect on Manoomin Survival Rate.” Burgstaler monitored four bays using trail cameras, looking for the presence of geese and water levels that exceed a threshold for healthy wild rice growth.
