Abstract Groundwater delivery of greenhouse gases (GHGs) to stream banks and riparian areas, before mixing with surface waters, has not been well quantified. We measured preferential groundwater GHGs within three reaches, found that discharging emitted more CO 2 were sources N O compared without actively groundwater, which less sinks. At one our concentrations 1.4–19.2 1.1–40.6 times higher than those in water, respectively, rates 1.5 1.6 water emissions per unit area. On average, 21% (range 0%–100%) at the bank waters. Preferential GHG may contribute substantially corridor be underestimated when using a channel‐centric approach estimate riverine budgets.
