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. -
Red River Floodway Operation Report Spring 2019
RED RIVER FLOODWAY OPERATION REPORT SPRING 2019 June 28, 2019 Manitoba Infrastructure Hydrologic Forecasting and Water Management Branch Water Management and Structures Division Printed on Recycled Paper EXECUTIVE SUMMARY The 2019 Red River spring flood resulted from above normal to well above normal winter snow fall in the upper Red River basin, including significant late season snowfall in the Fargo area, combined with normal soil moisture going into freeze-up in the fall. The March Outlook published by Manitoba’s Hydrologic Forecast Center estimated that the peak flow at Emerson could exceed the flow seen in the 2011 flood under favorable conditions, and exceed the 2009 flood under normal conditions. Under unfavorable conditions, the 2019 flow at Emerson was forecast to be second only to 1997 in the last 60 years of records. The observed peak at Emerson for the 2019 spring flood was approximately 60,700 cfs (1720.0 m3/s), and occurred on April 25. This is similar to the peak flow observed at Emerson in 2010. The 2019 peak flow measured at Emerson equated to a 1:15 year flood. However, due to the small contributions of tributaries in the lower portion of the basin, the peak natural flood flow at James Avenue only equated to a 1:6 year flood. The 2019 Red River spring flood was driven primarily by significant winter precipitation in the upper portion of the basin, and most of the tributaries on the Canadian side of the border had peaked long before the flood crest arrived. Ice was not a major concern on the Red or Assiniboine rivers in 2019, however, some ice jamming did occur north of the City of Winnipeg in the Selkirk and Netley Creek areas. -
Executive Summary
Page 1 of 26 Hydrologic Forecast Centre Manitoba Infrastructure Winnipeg, Manitoba FEBRUARY FLOOD OUTLOOK February 26, 2021 Executive Summary The February Flood Outlook prepared by the Hydrologic Forecast Centre of Manitoba Infrastructure reports the risk of major spring flooding in most Manitoba basins is low. Due to below normal soil moisture at freeze-up in southern and central Manitoba basins and below normal to well below normal winter precipitation until mid-February in these basins, the risk of major spring flooding is low for all southern and central Manitoba basins. Southern and central Manitoba basins include the Assiniboine River, Red River, Souris River, Pembina River, Roseau River and Qu’Appelle River basins and Interlake region. The risk of major spring flooding is low to moderate for northern Manitoba basins, including the Saskatchewan and Churchill River basins, because these basins have normal to above normal soil moisture and received below normal to slightly above normal winter precipitation. Most of the major lakes are below normal levels for this time of the year and within their operating ranges. The risk of flooding for most lakes is low. Soil Moisture Conditions at Freeze up: Soil moisture at freeze-up is one of the major factors that affects spring runoff potential and spring flood risk. Due to normal to below normal summer and fall precipitation, the soil moisture at freeze-up is normal to below normal for most of the southern and central Manitoba basins. Soil moisture is normal to above normal in the Little Saskatchewan River basin and in areas close to Brandon. -

Multiculturalism in the Past
MULTICULTURALISM IN THE PAST Leo Pettipas Manitoba Archaeological Society Multicultural: Of or having a number [two or more] of distinct cultures existing side by side in the same country, province, etc. — Gage Canadian Dictionary. In Canada, multiculturalism is considered to be of sufficient value as to merit support and promotion by way of legislation, official policy, and public programming. In Manitoba, multicultural heritage is celebrated each year in the many ethnic festivals and celebrations held throughout the province. The most conspicuous acknowledgement of our past and present cultural diversity is Winnipeg's internationally renowned festival of the nations, Folklorama. As an everyday aspect of human experience, multiculturalism ("cultural plurality" is perhaps a better term) is nothing new. Numerous examples of it are to be found well back into Manitoba's Indigenous past. Traditional Cree teachings, for example, speak of the "Ancients" -- people of distinct cultural heritage who lived in the North before and at the time of the arrival of the Crees themselves, and with whom the Crees became acquainted when they took up residence there many generations ago. Archaeological discoveries dating to before European contact in southern Manitoba are also believed to reflect cultural diversity in this region in Pre-Contact times. During the 1980s, archaeologists working on the riverbank at Lockport found evidence of a community whose roots lay to the south in what is now the American Upper Midwest. Their pottery in particular reflects non-local origins, as does their economy: they were cultivators of domesticated plants, unlike their local neighbours whose diet was based on the consumption of wild faunal and floral food resources. -
Recent Developments Along the Assiniboine Corridor in Brandon
Prairie Perspectives 199 Down by the riverside: recent developments along the Assiniboine Corridor in Brandon G. Lee Repko and John Everitt Brandon University Abstract: In the past few years, the previously neglected Assiniboine River corridor within the city of Brandon has shown signs of significant change and development. These changes have largely been the result of a realization, by both city officials and community members, that an important local recreational resource has been neglected or ignored by the majority of Brandon’s inhabitants for many years. A series of public meetings sponsored by the city led to the acceptance of a plan for the riverbank and the formation of a not-for-profit group to bring planned changes into reality. In the past three years, pre-existing developments have been brought under the auspices of Riverbank Inc. and a series of new initiatives have been started. This paper briefly describes the past and contemporary development of Brandon’s Assiniboine river corridor. Introduction The purpose of this paper is to outline and report upon the development of the Assiniboine River Corridor by “Riverbank Inc.” Riverbank Inc. is a non-profit “arms length” organisation incorporated by the Province of Manitoba in 1994. The aim of the organisation is to develop the tract of land along the banks of the Assiniboine River within the city of Brandon as a recreational area for the city and its region, and as a possible ecological focal point for tourist activity within southwest Manitoba (Figure 1). The ongoing transformation of the river valley has the potential to be one of the major changes to the face of Brandon since its incorporation in 1882. -
Sensitivity of the Red River Basin Flood Protection System to Climate Variability and Change

Sensitivity of the Red River Basin Flood Protection System to Climate Variability and Change SLOBODAN P. SIMONOVIC1∗ and LANHAI LI2 1 Department of Civil and Environmental Engineering, Institute for Catastrophic Loss Reduction, University of Western Ontario, London, ON, Canada; 2 Department of Civil and Environmental Engineering, University of Western Ontario, London, ON, Canada, currently with ROBBERT Associates Ltd., Ottawa, ON, Canada (∗ author for correspondence, e-mail: [email protected], Fax: 519 661 4273) (Received: 16 September 2002; in final form: 8 October 2003) Abstract. An original modeling framework for assessment of climate variation and change impacts on the performance of complex flood protection system has been implemented in the evaluation of the impact of climate variability and change on the reliability, vulnerability and resiliency of the Red River Basin flood protection system (Manitoba, Canada). The modeling framework allows for an evaluation of different climate change scenarios generated by the global climate models. Temperature and precipitation are used as the main factors affecting flood flow generation. System dynamics modeling approach proved to be of great value in the development of system performance assessment model. The most important impact of climate variability and change on hydrologic processes is reflected in the change of flood patterns: flood starting time, peak value and timing. The results show increase in the annual precipitation and the annual streamflow volume in the Red River basin under the future climate change scenarios. Most of the floods generated using three different climate models had an earlier starting time and peak time. -

Water Uses includedin the analysis are: munici- pal,industrial, agricultural, rural domestic, recreational, fish and wildlife, andother. The analysisof GDU impacts is confined to usesin Canada.The effects upon theseimpacts of variousalternatives andmodi- ficationsto the authorized GDU project were alsoanalysed. The following sections summarize theresults of the Uses Committee'sanalysis. (a)Municipal Use (1) Increasedcosts of municipal water supplytreatment: Deteriorated water quality will require, as a minimum measure,that currentlyinstalled or planned water treatmentplants be operated at peakefficiency, producing the best quality of water ofwhich they are capable.This measure represents an increased cost of $59,000 annually. Constituentssuch as nitrates, sulfates andsodium would remain at post- GDU levels since reduction of theseparameters is beyond the capability ofcurrent treatment facilities.
