The Base Hydrography Single Line Hydrography Network (SLNET) is the Alberta Environment and Parks base SLNET data set. It is an update of the Base Features HydroSLNET in Southern Alberta from orthophoto and various sources of provincial base data. It contains all captured single line representations of hydrographic features. In addition, single line representations of polygonal features and single line arbitrary network connectors are in the file.

Stream flow data are available for a number of streams across the province. New Stream flow data is available from June through September. Those who hold a Water Withdrawal for Irrigation Purposes Permit can use this tool to confirm the water flow in Island streams, and to determine whether they may legally draw water for irrigation purposes.

The hydrological regime of a stream plays a critical role in determining the biodiversity and ecological processes of aquatic, wetland and riparian ecosystems. As a result, hydrological characteristics provide important information on the integrity of freshwater systems and how they may be changing over time. The monitoring program assess and detect changes in a Streamflow Index of key hydrological measures in major transboundary watersheds at Kejimkujik. Stream water level is recorded hourly using in-situ water level data loggers.

This data set provides pesticide sample analyses results for stream water samples for the province’s Pesticide Monitoring Program. The sampling includes a total of 9 rivers across PEI, with at least 3 of the rivers being sampled each year. Stream water samples are collected at least once per year during wet weather sampling conditions. Department staff collects the samples, which are then sent to a laboratory for analysis.

Zones of homogeneous low flow characteristics

This data set provides pesticide sample analyses results for stream sediment samples for the province’s Pesticide Monitoring Program. The sampling includes sampling a total of nine rivers across PEI, with three of the rivers being sampled each year. Sediment samples are collected once in July, twice in August (once during a normal/dry weather and once during wet weather), and once in September. The two samples in July and September are collected during dry weather.

This dataset contains temperature data taken from 11 streams or rivers in Forillon National Park since 2008. Temperature data are collected hourly by a HOBO probe installed on the watercourse’s bottom in June and removed in September or October. For each watercourse studied, the temperature probe is installed at the benthic invertebrate community sampling site (CABIN) close to the site at which the electrofishing is carried out. Temperature data are particularly useful for assessing the quality of brook trout aquatic ecosystems in Forillon National Park.
