Objective(s): The objective of this study is to determine the water cycle processes acting in lakes and streams that affect the streamflow of Baker Creek and similar streams, and to understand how processes acting over smaller areas influence those that are predominant over larger areas.

Project Description: The objective of this study is to determine the water cycle processes acting in lakes and streams that affect the streamflow of Baker Creek and similar streams, and to understand how processes acting over smaller areas influence those that are predominant over larger areas.

Existing infrastructure, including 2 climate towers and a hydrometric gauge, will be built upon. Snow surveys will be conducted in spring. Streamflow will be measured at sites along Baker Creek. Evaporation from lakes will be estimated using water temperature measured with thermistor strings anchored on floats. Soil storage will be measured using soil moisture and well sensors. Meteorological conditions will be measured at two climate towers. Ground truthing of satellite images will take place to map surface wetness and estimate areas contributing to surface runoff. Field studies will focus on the spring melt and summer seasons.

A final Report will be submitted to the Aurora Research Institute. It is the investigator's intention to to regularly report, meet and discuss about the research progress with the Yellowknives Dene First Nation (YKDFN), North Slave Metis Alliance (NSMA), local INAC water managers. Informal discussions on both scientific and traditional knowledge of the water cycle will be held.
Fieldwork will be conducted from April 01 to December 31, 2008 at the Baker Creek basin, with a spring melt and summer camp at Vital Lake (62 36 N, 114 26.9 W).
