Southern Manitoba used to contain multiple marsh and bog wetlands. The wetlands were drained during the early 20th Century to increase the amount of arable land and attract more people to the province. These wetlands provided critical ecological functions such as flood mitigation, water filtration, and increased biodiversity. Since artificial waterways drained the wetlands, the surface water quality of the receiving waterbodies has suffered, with Lake Winnipeg taking the brunt of it. Two research questions drive this practicum: how can we, as landscape architects, integrate ecologically functioning wetlands into major tributaries of the Red and Assiniboine Rivers to improve their water quality? Given its physio-geographical specifics, what form might these take within the Red River Valley? In response to the prior questions, a constructed wetland design was proposed along a portion of the Norquay Channel. The agricultural landscape of the Red River Valley creates different various constraints for the design. The design includes important characteristics of natural wetlands, such as gentle slopes to facilitate the growth of wetland vegetation and a sediment deposition pond, all while working within a compact space to minimize the amount of agricultural land affected. Since the impact of the individual design site on improving Lake Winnipeg’s water quality would be limited, a more significant regional intervention is needed and proposed. Other fourth and fifth-order waterways, similar to that of the Norquay Channel, are proposed for similar interventions. Complete data from 2022 for surface water quality and water flow are used to estimate the impact of the individual design site on the nutrient loading of subsequent waterways. Two leading nutrients, nitrogen and phosphorus, could potentially be reduced within the wetlands by 46 to 56% and 70 to 89%, respectively.
