annex 7.5.8
7.5.8 Baker Creek Research Site, NWT

Overview
Research in the Baker Creek watershed (mainly by University of Saskatchewan and Carleton University) began in 2004, primarily in support of the Mackenzie GEWEX Study (MAGS II). At its outlet, located ~7 km north of Yellowknife, NWT, the basin drains ~155 km² of the Great Slave Lake watershed. The drainage comprises a series of large lakes, connected by short streams with highly variable flow regimes.

The basin is mainly exposed bedrock (40%), water bodies (23%), with coniferous forest hill slopes and deciduous forest (21%), peatlands and wetlands (16%). The basin overlies discontinuous permafrost. Overburden varies from less than 1 m to over 10 m: peat thickness ranges from a thin layer to ~1.2 m. The region’s climate is subarctic, with short, cool summers and long, cold winters. Mean annual precipitation is 289 mm, with ~41% as snowfall.

The basin hosts a range of instruments to observe hydrometric, meteorological and groundwater conditions, and snow surveys are conducted annually.

Variable name and units
Snow surveys: snow depth, density and water equivalent

Groundwater: soil moisture + temperature

Soil moisture: volumetric soil moisture at surface, 25 cm and 40 cm depth

Meteorological: Air temperature, relative humidity, wind speed, wind direction, four-component net radiation, turbulent fluxes, rainfall.

Hydrometric: water level and discharge

Water chemistry (ion suite, physicals, nutrients and dissolved metals), isotope data (d18O and d2H)

Soil temperature: temperatures at surface 25 cm and 40 cm depth

Soil moisture, temperature:
Volumetric soil moisture at surface, 25 cm and 40 cm depth
Six sites associated with wells, four in organic soil columns, two in brunisol soil columns.
Temperature also at one deep (>10 m) thermistor string and one in exposed bedrock to 50 cm depth

Groundwater:
Ten wells at mean maximum active layer depth: six associated with soil moisture and temperature, four in organic soil columns, two in brunisol soil columns.
