June 13th, 2023 12pm CT: MB Branch Webinar on “Long-term Trends in Riverine Nutrient Loads, Ratios and Streamflow in the Red-Assiniboine Basin”
What: MB Branch Webinar on “Long-term Trends in Riverine Nutrient Loads, Ratios and Streamflow in the Red-Assiniboine Basin”
When: June 13th, 2023 @ 12 pm CT
Where: Zoom
About:
There is concern that climate change is altering the magnitude and frequency of high-flow runoff events in northern prairie rivers, potentially leading to changes in nutrient loadings. As the ratio of nitrogen to phosphorus in riverine ecosystems is sensitive to flow variability, long-term nutrient ratios may also be impacted by these changing hydroclimatic conditions. Our goal is to evaluate long-term (25-year) trends in riverine nutrient concentrations, loads and ratios in major rivers within the Red-Assiniboine Basin and determine if these trends are associated with streamflow. Based on assessments of nutrient concentration data from 10 river monitoring stations within the Red-Assiniboine Basin in Canada and the United States, we will present annual trends in total and dissolved nutrient loads and ratios. Findings will assist in targeting management actions by identifying rivers where changing nutrient concentrations, loads, and ratios may be influencing productivity in the Red River and in Lake Winnipeg.
