East Trout Lake, Saskatchewan (54°21'N, 104°59'W)

The East Trout Lake monitoring site is located in a 2 km2 clearing in the western boreal forest region near the river mouths of the East Trout and Nipekamew Lakes. The forest terrain in the surrounding area is slightly rolling and very boggy. A mixture of birch, pine, aspen and spruce surround the observatory. The East Trout Lake site is located 40 km north of Candle Lake site.

The greenhouse gas measurement program began at East Trout Lake through collaboration with Fluxnet Canada. The site and 100m communication tower is owned by SaskTel. In collaboration, NOAA ESRL conducts a regular weekly aircraft air sampling program near this site as part of the North American Carbon Program.
