In permafrost dominated regions, a gap persists in our understanding of water resources, the influence of groundwater, and the impact of climate change at the regional scale. Regional scale modelling can help to advance the understanding of these impacts by integrating with regional climate models. For regional modelling to be tenable, ongoing development of modelling methods and conceptualizations is required. By developing a fully integrated numerical groundwater-surface water climate model using HydroGeoSphere (HGS) (Aquanty 2021) for a gauged basin within the discontinuous permafrost zone, this dataset allows the verification of existing numerical methods and the testing of various conceptualizations of integrated groundwater-surface water flow in permafrost regions at the regional scale. This work informs future modelling and forecasting of regional water resources in permafrost regimes.

Stormwater ponds are artificial structures that are critical components of stormwater management systems in many Canadian cities. They serve to prevent flooding of urban areas during excess rainfall. Stormwater ponds also contribute to environmental health by allowing the settlement of dirt and solids from stormwater to the bottom of the pond. As a result, the sediments of stormwater ponds can become enriched with potentially harmful contaminants. The health risks posed to anglers by contact with stormwater and sediments and consumption of fish from stormwater ponds are not well characterized. The City of Lacombe (Alberta) is a municipality with two stormwater ponds stocked with sterile fish for angling. Alberta Health collected water, sediment and fish from these two ponds over two seasons (fall 2010 and spring 2011) and analyzed the samples for a suite of contaminants. Water samples were collected from three sites at each pond and three depths for each site (n=40; nine samples plus one replicate sample per pond per season). Sediment samples were collected from the same three sites at each pond (n=12; three samples per pond per season). Fish samples (rainbow trout) were collected in fall 2010 (n=18; eight from East Pond and ten from Len Thompson Pond). For the contaminant analysis, all samples (water, sediment and fish) were tested for parent and alkylated polycyclic aromatic hydrocarbons (PAHs). Additionally, water samples were tested for routine chemicals, trace metals, pesticides and volatile organic compounds (VOCs), and fish muscle tissue was tested for total mercury.

All bank edges (of rivers, lakes, and wetlands), delimiter edges, glacier edges, and administrative boundary edges. These are the linear features that makeup the polygonal waterbodies

All fundamental watershed polygons generated from watershed boundary lines, bank edges, delimiter edges, coastline edges, and administrative boundary edges

Polygons delimiting the watershed group boundary, which is a collections of drainage areas. In-land groups will contain a single polygon, coastal groups may contain multiple polygons (one for each island)

Surficial geologic units are unconsolidated materials overlying bedrock. The dataset represents a general description of the stratigraphy and geology, including geologic unit thickness, morphology, age and rank. It features a list of the geologic unit names and types of sediment in the hydrogeological unit. While the preferred format to deliver this data is by using a shapefile and its linked attributes, this dataset can be delivered also by providing link to external data which should have at least the same properties or also by joining a georeferenced image of the map.

This data is intended to identify Canadian fresh waters which require additional measures (e.g., ballast water exchange and treatment) prior to release, as described in https://tc.canada.ca/en/marine-transportation/marine-safety/list-canada-s-designated-alternate-ballast-water-exchange-area-fresh-waters-tp-13617e-2021. The data is not intended for navigation purposes.According to Canada’s Ballast Water Regulations, vessels which are managing ballast water to meet the ballast water performance standard cannot release ballast water into fresh waters unless that ballast water was first exchanged in accordance with the ballast water exchange standard. For the purpose of this requirement, Canadian fresh waters are the following:- the waters at the Port of Kitimat and waters in or upstream of the Kitimat Arm, east of a line between Hilton Point and Steel Point;- the waters at the Port of Stewart and waters in or upstream of the Portland Canal, north of a line between Portland Point and Ramsden Point;- the waters of all Fraser River ports that are: -- east of Tilbury Island in the main arm of the Fraser River including Annacis Island and New Westminster docking areas; and -- east of the eastern tip of Mitchell Island in the north arm of Fraser River;- the waters of the Saguenay River ports and waters upstream of L’Anse-Creuse;- the waters of all St. Lawrence River ports and waters west of the east point of Ile d’Orléans including the port of Quebec City;- all Canadian waters of the Great Lakes Basin; and- the waters of Happy Valley-Goose Bay and waters of Lake Melville west of Rabbit Island.Legal Constraints: Users should be aware that the polygons depicting areas requiring additional measures to manage ballast water are intended for illustration only and should not be used for navigational or legal purposes.

The Maritimes Region is divided into seven Clam Harvesting Areas (CHA).CLAM HARVESTING AREA 1 is described as follows:The inland and tidal waters of the counties of Colchester, Cumberland and Hants that border and flow into the Bay of Fundy.CLAM HARVESTING AREA 2 is described as follows:The inland and tidal waters of the counties of Annapolis, Digby and Kings.CLAM HARVESTING AREA 3 is described as follows:The inland and tidal waters of Yarmouth County.Time restrictions for Clam Harvesting Area 3: No person shall fish for clams from sunset each Saturday until sunrise on the following Monday (closed Sundays) in the boundaries of Clam Harvesting Area 3.CLAM HARVESTING AREA 4 is described as follows:The inland and tidal waters of the counties of Shelburne, Queens and Lunenburg and that portion of Halifax County west of Pennant Point (as defined in the Territorial Sea Geographical Coordinates Order (C.R.C., c. 1550), Schedule I, Area 4).CLAM HARVESTING AREA 5 is described as follows:The inland and tidal waters of Guysborough County and that portion of Halifax County east of Pennant Point (as defined in the Territorial Sea Geographical Coordinates Order (C.R.C., c. 1550), Schedule I, Area 4).CLAM HARVESTING AREA 6 is described as follows:The inland and tidal waters of the counties of Richmond and Cape Breton, all of Victoria County except that portion between Cape North and Inverness County and that portion of Inverness County that borders on the Bras d'Or Lakes.NEW BRUNSWICK - BAY OF FUNDY CLAM HARVESTING AREA 7 is described as follows:The inland and tidal waters of the counties of Charlotte, Saint John and Albert that flow into the Bay of Fundy.

Groundwater flow is the movement of water in an aquifer or hydrogeological unit. The dataset shows groundwater flow rate and direction in the hydrogeological unit. Groundwater flow is establish from piezometric surface map. The method used to create the dataset is described in the metadata associated with the dataset. The dataset represents a description of the flow, including rate in m/d, direction, date and source. Typically, the data provided will not be in the form of a shapefile with linked properties but in the form of an image that sketches the groundwater flow. The image could also represent a cross section of the hydrogeologic units showing the regional trends of the groundwater flow.
