This dataset describes biomass and methylmercury concentrations in zooplankton, other invertebrates, fish, and coarse and fine detritus samples collected at the outflow locations of Brownlee and Oxbow Reservoirs in the Snake River Hells Canyon Complex. Based on the sampling locations, the sampled materials were presumed to have flowed through the dam turbines or over the spillway, thereby representing biological export from the reservoirs. Samples were collected biweekly at each location over a sixteen-month period, June 2018 – September 2019. Sampling and analysis methods are described in the Processing Steps section of the metadata.
