  • Water Quality Report
    Central Assiniboine Watershed Integrated Watershed Management Plan - Water Quality Report October 2010 Central Assiniboine Watershed – Water Quality Report Water Quality Investigations and Routine Monitoring: This report provides an overview of the studies and routine monitoring which have been undertaken by Manitoba Water Stewardship’s Water Quality Management Section within the Central Assiniboine watershed. There are six long term water quality monitoring stations (1965 – 2009) within the Central Assiniboine Watershed. These include the Assiniboine, Souris and Cypress Rivers. There are also ten stations not part of the long term water quality monitoring program in which some data are available for alternate locations on the Assiniboine, Souris, and Little Saskatchewan Rivers. The Central Assiniboine River watershed area is characterized primarily by agricultural crop land, industry, urban and rural centres. All these land uses have the potential to negatively impact water quality, if not managed appropriately. Cropland can present water quality concerns in terms of fertilizer and pesticide runoff entering surface water. There are a number of large industrial operations in the Central Assiniboine Watershed, these present water quality concerns in terms of wastewater effluent and industrial runoff. Large centers and rural municipalities present water quality concerns in terms of wastewater treatment and effluent. The tributary of most concern in the Central Assiniboine watershed is the Assiniboine River, as it is the largest river in the watershed. The area surrounding the Assiniboine River is primarily agricultural production yielding a high potential for nutrient and bacteria loading. The Assiniboine River serves as the main drinking water source for many residents in this watershed. In addition, the Assiniboine River drains into Lake Winnipeg, and as such has been listed as a vulnerable water body in the Nutrient Management Regulation under the Water Protection Act.

Minister’s Message From the grasslands in the southwest to the Taiga Shield lakes of the north, we in Saskatchewan are blessed with richly diverse ecosystems. Over the past few decades, we have come to understand more about the nature of these ecosystems, and how we rely on them to support our economy and our overall quality of life. We have also increased our understanding of the responsibility we bear to assess, protect and improve our province’s environmental health, in balance with our social and economic priorities, for the good of present and future generations. We face a number of challenges regarding our water’s quality and availability. It is up to Saskatchewan people to determine how we will meet these challenges. The Saskatchewan government has taken a leadership role in assessing, protecting and managing our source waters by addressing them at the watershed level. The State of the Watershed Reporting Framework represents a critical step in understanding our relationship with Saskatchewan’s watersheds, as well as our role as stewards of our environment. For the first time in Saskatchewan, this framework will integrate the information collected by numerous provincial and federal agencies and present it in an easily understandable, technically sound report- card format.

  • The Role of the Assiniboine River in the 1826 and 1852 Red River Floods
    58 Prairie Perspectives The role of the Assiniboine River in the 1826 and 1852 Red River floods William F. Rannie, University of Winnipeg Abstract: Hydrologic conditions in the Assiniboine River basin during the extreme Red River floods of 1826 and 1852 are evaluated from historical sources. In both years, commentaries suggest that extreme floods also occurred in the Assiniboine, with the dominant source of water being the Souris River; in 1852 (and possibly 1826), the Qu’Appelle River discharge was also very high. It is concluded that the Assiniboine made large contributions to each of the epic historic floods, in contrast to its minor contribution to ‘natural’ flow in 1997. If reasonable allowance is made for the Assiniboine’s contribution to the estimated total historical flows of the Red, it is likely that the 1997 discharge of the Red alone (upstream of The Forks) was larger than in 1852, but still much smaller than in 1826. Key words: Assiniboine River, Red River, flood history, return period, 1826, 1852 Introduction The historic floods of 1826 and 1852 which devastated the Red River Settlement are the benchmarks against which modern floods in Winnipeg are judged. Until 1997, these floods had discharges far beyond any in the period of gauge records (Table 1), and even the third largest historic flood (in 1861) paled in comparison. The 1997 ‘natural’ (i.e., uncontrolled) discharge in Winnipeg almost equalled the normally-accepted value for the 1852 flood and precipitated planning to increase the level of Winnipeg’s protection to encompass a recurrence of 1826-magnitude or even larger floods.
