Environment and Climate Change Canada’s Lake Winnipeg Basin Office invites you to attend this virtual information sharing webinar featuring talks from two research projects funded by the Lake Winnipeg Basin Program.
Join us for this webinar featuring projects by InnoVantage Inc. on municipal wastewater lagoon monitoring and by Native Plant Solutions on phosphorus retention in conventional and naturalized storm water ponds.
Date: Wednesday, March 9th, 2022
Time: 10:00 am – 11:00 a.m., Central Standard Time (Chicago, GMT-06:00)
This webinar is part of an ongoing series of information sharing events related to nutrient reduction efforts in the Lake Winnipeg Basin. Please feel free to share this invitation and the MS Teams link below with others that might be interested. There is no need to register and there is no fee to attend.
Presentation abstracts:
Analysis of variance of phosphorus in lagoons discharge during the discharge period in Manitoba.
Gavin van der Linde and Arman Vahedi, InnoVantage Inc
In 2021 we conducted a pilot project and monitoring study on a number of municipal lagoons in southern Manitoba. The pilot project was to develop an affordable, efficient phosphorus removal system for municipal lagoons. During the research portion of the project, we monitored 14 different municipal lagoon cells, testing the phosphorus levels 6 times during the discharge period. The aim of the study was to see how the phosphorus levels varied over the discharge period. The lagoons were further classified according to how they treated phosphorus.
Phosphorus retention in conventional and naturalized stormwater ponds within the Lake Winnipeg Basin.
Bruce Friesen-Pankratz, Nicholson Jeke, and Lisette Ross, Native Plant Solutions, Ducks Unlimited Canada.
Phosphorus retention within stormwater ponds is largely determined by the extent of their emergent vegetation cover. Conventional stormwater ponds (CSPs) do not have extensive emergent vegetation zones due to their steep slopes and deep water. Conversely, naturalized stormwater ponds (NSPs) are designed to support extensive emergent vegetation. While NSPs as Best Management Practices for stormwater management are now required within some Lake Winnipeg Basin jurisdictions few studies of their ability to retain phosphorus have been completed. Our study compared total phosphorus concentrations in the surface water of 8 CSPs and 8 NSPs in Winnipeg during the 2021 open water season (June through November).
