These datasets include information on Licences under the Water Act collected by Alberta Environment and Protected Areas, for both active and inactive authorizations for surface water and groundwater diversions under a Licence (defined as a “diversion of water” under the Water Act).

Cyanobacteria (also referred to as blue-green algae) are common photosynthetic bacteria that live in surface waters. Under favorable conditions, such as warm water and high nutrient content, these bacteria can form nuisance “blooms”. The presence of blooms in recreational water causes unpleasant aesthetics and exposure to some toxin-producing blooms may pose potential health risks. Contact with blooms can cause skin rashes and irritation, itchy eyes, and ear infections. Inhaling water may cause allergic-like reactions, runny noses or sore throats. Ingestion of toxins can cause a range of symptoms (e.g., hepatotoxic or neurotoxic effects, and even death). There has been increased public awareness as a result of research over the past 25 years, recent monitoring efforts, and increased public education on the topic. In 2009, Alberta Health and Alberta Health Services began seasonal monitoring for cyanobacterial blooms at high use recreational beaches. In 2019, beach operators took over the sampling role from Alberta Health Services under the Alberta Safe Beach Protocol. Water is collected from shallow water adjacent to beaches and submitted to laboratories for analysis of cyanobacterial bloom indicators. These data, along with visual inspection, are used to characterize potential cyanobacterial blooms and issue recreational water use advisories when cyanobacteria are found in a waterbody at levels that can affect human health. The data presented below is organized into two files that contain supporting data and key cyanobacterial bloom indicators, and counts of individual cyanobacteria species, respectively. Each row represents a water sample collected from an Alberta beach. In the cyanobacteria species data, each water sample will have many associated rows of data. Each column represents a piece of information about that water sample (e.g., key indicators and supporting information) that is used to characterize cyanobacterial blooms. Data from the current year (2026) should be considered preliminary and might change with further quality control/quality assurance steps. This dataset is updated monthly between June and September each year. For more information on these indicators please refer to the column descriptions “Usage Considerations” associated with this dataset.

Long-term freshwater quality data from federal and federal-provincial sampling sites throughout Canada's aquatic ecosystems are included in this dataset. Measurements regularly include physical-chemical parameters such as temperature, pH, alkalinity, major ions, nutrients and metals. Collection includes data from active sites, as well as historical sites that have a period of record suitable for trend analysis. Sampling frequencies vary according to monitoring objectives. The number of sites in the network varies slightly from year-to-year, as sites are adjusted according to a risk-based adaptive management framework. The Great Lakes are sampled on a rotation basis and not all sites are sampled every year. Data are collected to meet federal commitments related to transboundary watersheds (rivers and lakes crossing international, inter-provincial and territorial borders) or under authorities such as the Department of the Environment Act, the Canada Water Act, the Canadian Environmental Protection Act, 1999, the Federal Sustainable Development Strategy, or to meet Canada's commitments under the 1969 Master Agreement on Apportionment.

Data on trees belonging to the municipality, referred to as “public domain”: street and off-street trees (parks and public squares). Please note that in many cases, the City's data on the spatial location of trees may be inaccurate or out of date. In addition, in some boroughs, park trees are not indicated.**This third party metadata element was translated using an automated translation tool (Amazon Translate).**

The product of the land rights layer (leases) contains the centroid or, in some cases, the outline of rental leases granted by the Government of Quebec, or granted by MRCs and cities that are signatories of an agreement to delegate land management and the management of sand and gravel exploitation on land under the domain of the State. The main components are: * Personal purposes (e.g.: main residence, cottage, summary shelter in the forest) * Commercial purposes (e.g. outfitter, tourist site, fish farming, sawmill) * Public interest purposes (e.g. telecommunications) * Municipal purposes (recreational or sports activities) * Community purposes (shelter, shelter, relay, trail) Depending on the case, the data sources are: * GPS inputs * Aerial photographs * Surveying surveys**This third party metadata element was translated using an automated translation tool (Amazon Translate).**

The Hydrogeological Information System (HIS) contains the physical characteristics of wells and boreholes (location, depth, stratigraphy encountered, etc.) mainly from drilling reports transmitted by well drillers for groundwater sampling installations serving private drinking water residences. The geographic coverage corresponds to all of Quebec although most of the data are found in the south of the province. A monthly update is made. SIH data can be useful for hydrogeology professionals, the academic community and a wider audience in order to make interpretations on portions of territory, for example on the depth of the rock in a sector, or to consult more precise points of information such as the description of a specific identified well.**This third party metadata element was translated using an automated translation tool (Amazon Translate).**

Data on the felling of trees belonging to the municipality designated as “public domain.” This data contains street and off-street trees (parks and public squares) since the period between 1989 and 1991, the first period of massive inventory in Montreal. Please note that in many cases, data concerning the spatial location of trees may be inaccurate. In addition, it is important to mention that this set only shows the tree felling collected in Montreal's centralized system. Some boroughs therefore do not fit into it. For more information on public trees in Montreal, please consult the set: [Public trees on the territory of the City.] (/dataset/trees)**This third party metadata element was translated using an automated translation tool (Amazon Translate).**
