Restrictive water level regulation in the Saint Lawrence River over the past 50 years has had a profound impact on ecosystem health. Currently, there are no explicit plans to determine how the restoration of more natural water level regimes in the St. Lawrence will impact water quality, although great effort has been made to develop adaptive management as the proper strategic approach. Water quality sensor arrays will be continuously operated in the Moses-Saunders hydropower dam to provide data that can relate change in water quality to changes in water levels. Mercury will be measured in water flowing through sensor arrays as well as in wetlands upstream that have the potential to release Hg with changing water level scenarios. The objective is to collect water quality data and relate this to water levels, to assess the potential for changing water levels to release Hg into the river and to produce three audience-appropriate videos to describe this important endeavor.
