Hydrometeorological and hydrological data from Baker Creek Research Watershed, Northwest Territories, Canada Release V.3

Abstract. The V.3 data release from the Baker Creek Research Watershed documents hydrometeorological and hydrological conditions from 2003 to 2025. Baker Creek drains 155 km² of subarctic Canadian Shield terrain in Treaty 11 in Canada's Northwest Territories. Half-hourly hydrometeorological data are available from the three most common landscape types, including exposed Precambrian bedrock ridges, open black spruce forest and lakes. Hydrometeorological data include radiation fluxes, precipitation, temperature, humidity, winds, barometric pressure and turbulent energy fluxes. Data from terrestrial sites include ground temperature and soil moisture. Spring maximum snowpack water equivalent, depth and density data are included. Daily streamflow data are available for six nested watersheds ranging in size from 9 to 155 km². These data are unique in this remote region and provide communities with an opportunity to advance understanding of the hydrological response of a subarctic watershed subject to a warming trend and precipitation cycles. The data described here are available from the Federated Research Data Repository at: https://doi.org/10.20383/103.01579 (Spence and Hedstrom, 2026).
