Since 2009, up to nine (9) streams (White River, Willow River, Oiseau Creek, White Gravel River, North Swallow River, Swallow River, Cascade River, Tagouche Creek and Imogene Creek) are monitored with stream temperature HOBO loggers to assess thermal suitability for Brook trout (Salvelinus fontinalis). In 2016 and 2017, a second logger was deployed at each of the streams. Loggers are deployed in each stream during the summer, between Lake Superior and the first barrier. Data from the two loggers are analyzed separately for each week and the lower maximum weekly trimean temperature from each stream is used.

Benthic samples are collected from 6 streams (Oiseau Creek, White Gravel River, North Swallow River, Swallow River, Tagouche Creek and Imogene Creek) in mid to late September using standarized methods for collecting invertebrates developed by the Canadian Biomonitoring Network (CABIN). Five sub-measures are calculated for the status of this measure; family richness, percent oligochaeta, the Hilsenhoff family biotic index (HfBI), Ephemeroptera - Plecoptera - Tricoptera (EPT) index and a multivariate community metric (90th percentile Hellinger's Distance).

The dataset contains data for placer watersheds locations. The dataset covers 18 watersheds within the Yukon Territory. The following watersheds form the principle boundaries of the dataset: Big Creek, Big Salmon River, Forty Mile River Indian River, Klondike River, Mayo River McQuesten River, Nisutlin River, Nordenskiold River Pelly River, Sixty Mile River, Southern Lakes (Yukon) Stewart River, White River*, Yukon River North Yukon River South, Alsek River, Liard River *Note - A small portion of the headwaters of the Tanana River (Yukon) watershed is associated within the boundaries of the White River watershed

Water quality data is based around two of the largest lakes in Prince Albert National Park – Kingsmere and Waskesiu. Data is collected monthly from May through September each year, with additional water chemistry sampling in March. Water chemistry and Secchi disk depths are sampled by boat at three open water locations, and E.coli levels are tested from three high use beach locations. Discharge measurements are taken for Waskesiu Lake inflow (Kingsmere River, Mud Creek) and outflow (Waskesiu River).

Fish Habitat Reconnaisance Survey - Fraser Tributaries, Yalakom River, and Tyaughton Creek Watersheds

Water quality and suspended sediment monitoring and surveillance data collected from the connecting channels of the Great Lakes to determine baseline water quality status, long term trends and spatial distributions, the effectiveness of management actions, determine compliance with sediment quality objectives and identify emerging issues are included in this dataset. The Great Lakes are joined together by river systems known collectively as connecting channels, including the St. Marys River, the St. Clair River (and Lake St. Clair), the Detroit River, the Niagara River, and the St. Lawrence River. Uniquely, the connecting channels originate from the outflow of one or more large, oligotrophic lakes rather than the accumulation of a network of tributaries.

As part of a water quality survey, stream samples were collected throughout the Big Creek, Lynn River, and Nanticoke Creek Watershed in Southern Ontario in 2008. The project was undertaken to examine stream water quality under base flow conditions and was done in support of Environment and Climate Change Canada’s ongoing work to assess the status of the waters of the Great Lakes Basin. Sample collection was done at roadside stream crossings using a stainless steel bucket. Field parameters (temperature, specific conductivity, dissolved oxygen, pH) were determined on site using a YSI 600QS Sonde.

This data set was created upon direction from Yukon Government, DIAND, Yukon Region and CYFN following consultations with citizens of Carcross, Ross River, Old Crow and Beaver Creek. The maps for Burwash Landing, Destruction Bay, Pelly Crossing and Deep Creek reflect the community boundaries of the respective First Nation Final Agreements.
