Hydrography (HY) Iceland is one of 12 themes in the European Location Project (ELF). The purpose of ELF is to create harmonised cross-border, cross-theme and cross-resolution pan-European reference data from national contributions. The goal is to provide INSPIRE-compliant data for Europe. A description of the ELF (European Location Project) is here: http://www.elfproject.eu/content/overview Encoding: INSPIRE version 4

PURPOSE: To monitor juvenile Atlantic salmon densities over time. DESCRIPTION: Indices of freshwater production are derived annually from electrofishing surveys in Southeast New Brunswick. Juvenile Atlantic salmon abundances at sites, divided by age or size group and reported in terms of number of fish per habitat area sampled (density), are obtained using successive removal sampling or catch per unit effort sampling (which is calibrated using successive removal sampling data). Sampling intensities vary among years and among rivers. This dataset comprises raw data on all fish captured and effort invested in the course of monitoring juvenile Atlantic salmon in Southeast, New Brunswick, from 1974 to 2024. Sampling was focused on habitat suitable for Atlantic salmon, and capture of any other species was incidental. PARAMETERS COLLECTED: Distribution (ecological); species counts (ecological); fish lengths (biological); fish weights (biological); point (spatial). USE LIMITATION: To ensure scientific integrity and appropriate use of the data, we would encourage you to contact the data custodian.

Watershed polygons representing the Major Watershed Code Numbers of BC. Based on the 1:50,000 scale Canadian National Topographic Series of Maps.

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.

BC active and discontinued hydrometric stations (surface water level and flow data) that are part of the provincial hydrometric network managed under a national program jointly administered under a federal-provincial cost-sharing agreement with Environment and Climate Change Canada (ECCC).

Province-wide SDE spatial layer displaying consumptive water licence points of diversion for drinking water systems. In the context of this layer, Drinking Water Systems means two or more water licences for domestic purposes at a single POD; and/or a water licence(s) for any other purpose indicating a water diversion and distribution system supplying water directly to residences and/or buildings for human consumption. This layer is an instantiation of the spatial view WLS_BC_POD_DRINKING_SOURCES_SVW
