Found 10 records similar to Lake Water Quality - Kejimkujik
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.
What? Water samples are collected in Cape Breton Highlands National Park in various freshwater lakes and streams. When? Water samples are taken in select park lakes biannually (ie.
The Canadian Council of Ministers of the Environment (CCME) has designed a Water Quality Index (WQI) to translate complex water quality data into an overall integrated score from 0-100. This score is based on the number of measured variables, which have observations exceeding water quality thresholds (i.e., scope); the number of these exceedances in the dataset (i.e., frequency); and the magnitude by which the observations exceed the guidelines (i.e., amplitude). These water quality parameters are crucial indicators of the physical, chemical or biological conditions in aquatic systems and processes. The purpose of the water quality monitoring program at Kouchibouguac National Park is to use this index to calculate a score and evaluate the status of our freshwater ecosystems.
The effects of climate warming, eutrophication, air pollutant inputs and forestry activity that occurred before La Mauricie National Park was created influenced and continue to influence today water quality in the park. These stress factors threaten the natural evolution of aquatic ecosystems. On several small lakes, the quality of the habitat has not ensured the maintenance of the eastern brook trout population and has decreased the beaver population. In order to monitor the aquatic ecosystems, sampling of a number of predetermined lakes is being carried out and water quality is being measured by evaluating parameters related to acidification, eutrophication, general water quality, and oxygen and temperature conditions.
Wetland water quality is an important determinant of wetland condition. Wetland water quality can be strongly influenced by many stressors, including land use change and forestry practices, acid deposition and long-range transport of air pollutants and climate change. Monitoring water quality in peatlands provides an early warning of potential threats to wetland ecosystems. Water samples are collected in May from 10 wetland wells once per year.
This dataset is a collection of measurements which make up two water quality indexes: Nutrients, Physical and Major Ions (NPMI) Index and Metals Index. The measurements are taken at two different locations along the Hornaday River annually in early-July. Project Rationale: Water quality is a widely used measure for assessing and monitoring the condition of freshwater ecosystems. The chemical composition of water influences the biological productivity and species composition of rivers.
What? Water samples are being collected in various wetlands in Cape Breton Highlands National Park. When? The monitoring frequency for wetland water quality is annually with samples being collected in the spring of the year.
Historical water quality data measured on a continuous basis at over 23 locations across Canada is included in this dataset. Most locations include hourly temperature, dissolved oxygen, pH, specific conductance and turbidity. Data are collected by Environment and Climate Change Canada (ECCC) and in partnership with other federal departments and provinces and territories to enable the detection of short-term water quality events, and to determine trends in water quality, especially at transboundary sites (or Federal waters) in support of Federal legislation and international agreements, or to report on the status of Government of Canada priority aquatic ecosystems.
The Canadian Environmental Sustainability Indicators (CESI) program provides data and information to track Canada's performance on key environmental sustainability issues. The water quality indicators measure water conditions for various locations across Canada. It combines measurements of a wide range of substances found in water samples. The indicator focuses on how suitable the water is for plants and animals; aquatic life is present in all water bodies, is sensitive to pollution, and reflects the overall health of aquatic ecosystems.
The timing of ice formation and breakup is an important factor affecting aquatic life and ecosystems. Continued monitoring is important due to potential changes the timing of ice formation and breakup, and therefore aquatic productivity. This study uses data from Water Survey of Canada guages and remote cameras to determine annual dates of ice breakup and freeze up at 1 lake and 3 river locations.
