Abstract
Key Points CH 4 ebullition rates decreased by 98% and CH 4 diffusion decreased by 32% on a longitudinal gradient from reservoir inflow to dam Ebullition was driven by physical variables upstream and phytoplankton downstream; diffusion was most related to phytoplankton Despite large variation in CH 4 emissions longitudinally, time series models well captured the dynamics of emissions from a small reservoir
