Abstract: Accurate low flow measurements are important in groundwater-fed streams in order to assess in-stream flow requirements and the nature of stream interactions with groundwater, as well as the potential impacts of climate variability and climate change. Variability in stream discharge was measured over the low flow season in Bertrand Creek, Pepin Brook and Fishtrap Creek, which drain the Abbotsford-Sumas aquifer in southwest British Columbia and northwest Washington State. Discharge was measured to quantify variability: (1) along the length of the stream and relate those variations to differing groundwater contributions over the low flow season, and (2) across a series ...
