4 Water is a shared jurisdiction Provincial Provinces have the lead on water management and protection within their boundaries Provincial legislative powers include: flow regulation authorization of water use development water supply pollution control thermal and hydroelectric power development Federal Municipal Provision of water and wastewater services, including drinking water Land use planning policies EXCLUSIVE ROLES: fisheries, navigation, relations with foreign governments, public property (including government buildings, National Parks, migratory bird sanctuaries, Canadian Forces bases, National Historic Sites, national wildlife sanctuaries, etc.) and lands reserved for Indians Shared Drinking water, pollution prevention, water quantity/supply monitoring, aquatic ecosystems, domestic interjurisdictional waters, infrastucture, environmental assessment, science/research, Heritage Rivers, etc. Page 4 Discussion Document (For Internal Use Only)
5 So where does Meteorological Service of Canada get involved? Federal Water Canada US most water subject to treaty and orders Columbia, Milk, St. Mary s Souris, Red River,Lake of the Woods, Great-lakes/St. Laurent, St Croix, Yukon. Transboundary inter-provincial basins Saskatchewan- Nelson, Mackenzie. Navigable Rivers (Coast-Guard) Water Survey for 100 years Information now-casting and hindcasting service cost shared with the provinces. 100% cost recovery for non-federal interest. Transboundary (IJC and Domestic Boards) Water Units All MSC regions have some responsibility Applications and Modeling supports WSC and Transboundary Units... as well as provinces and territories.

10 100 years of service 100 years ago. Minister of the Interior at the time was Frank Oliver MP from Edmonton Sir Wilfred Laurier was PM. Deputy Minister was W.W.Cory First published Data : Report of Progress of Streamflow for Calendar Year, 1909 by P.M. Sauder, Chief Hydrographer. The first appropriation made by Parliament for hydrographic work was in as this vote was not available until the season was too far advances, only a part of it was used in purchasing equipment in 1909 In Organizing the Hydrographic Surveys, it was realized with the funds available, it would be impossible to make complete investigations of the whole water supply Spent two years in Montana with USGS Page 10 Discussion Document (For Internal Use Only)
11 Boundary Waters Treaty - Principles Equal and similar rights to use of boundary waters Order of precedence of use sanitary/domestic, navigation, power generation and irrigation Structures/diversions not to affect levels and flows on the other side Must not pollute water on either side to the injury of health or property on the other side rules upon applications for approval of projects affecting boundary or transboundary waters (orders of approval) and may regulate the operation of these projects (review of orders) investigates issues referred by governments and makes non-binding recommendations for resolution (references) Page 11 Discussion Document (For Internal 11 Use Only)

15 Water Resources Modelling Description: An enhanced hydrological service that builds on our existing infrastructure and our mandated responsibilities (IJC and interprovincial boards) but bringing this forward into a new paradigm, that: optimizes the delivery of services building on key existing EC infrastructure; and provides a new level of information products to enhance EC mandated requirement for hydrological services; and, to provide tools and information services. Long Term and Short Term Objectives are focused in 3 Main Thematic Areas: Development of Hydro-meteorological and Hydraulic models. Development of water cycle applications. Development of integrated and regional studies or projects. Page 15 Discussion Document (For Internal Use Only)

24 Green Kenue Software Tools Developed by the National Research Council, largely funded by EC Yearly development aims to support EC projects, while providing tools for regional hydrologist and the Canadian water resource community Provides data preparation, analysis, and visualization for hydrologic modellers DEM and land cover imagery processing, tools for manipulation of time-varying and gridded data Integration of environmental data: HYDAT, CDCD, NARR, GRIB Pre & post-processing for the WATFLOOD and HBV-EC models FREE Page 24 Discussion Document (For Internal Use Only)
25 Canadian Environmental Sustainability Indicators (CESI) CESI measure the progress of the Federal Sustainable Development Strategy, report to Canadians on the state of the environment, and describe Canada s progress on key environmental sustainability issues. WSC is responsible for the yearly calculation of the Water Quantity Indicator: 30-yr hydrologic normals are calculated at over 1000 long-term hydrometric stations across Canada. WSC reports yearly on the state of water levels or flows at each stations with respect to calculated normals. Stations are categorized as Low, Normal or High. Page 25 Discussion Document (For Internal Use Only)
26 Canadian Environmental Sustainability Indicators (CESI) Indicator calculation tool recently developed within Green Kenue. Allows users to: Calculate water level and flow indicators using HYDAT.mdb Visualize data used to create indicator and further understand yearly conditions (i.e. higher than normal spring flows) Customize calculation criteria and observe impact on normals and indicator result Page 26 Discussion Document (For Internal Use Only)
27 Canadian Environmental Sustainability Indicators (CESI) Further development of the Green Kenue Indicator Tool is planned to include Indicators of Hydrological Alteration (IHA) Suite of well-established indicators developed by the Nature Conservancy to analyze hydrometric data in an ecologically-meaningful manner. EC (Water & Climate Impacts Research Centre and Canadian Rivers Institute) is now exploring modification to the IHA for its application in the Canadian context Characterization of the influence of ice cover Calculation of indicators for seasonally-operated stations WSC is aiming to produce indicators that complement those currently published by CESI and further describe the state of water quantity in Canada.
