Water is one of the most versatile tools in astrochemical studies of low-mass star formation. Its high abundance of ~10-4 in shocks and in hot gas (T>100 K) make water an excellent probe of the energetic feedback of a young star onto its environment. In addition, spectrally resolved observations provide important information on the kinematics and dynamics of protostars. In this talk we present highlights from water spectra observed with the Herschel Space Observatory toward a sample of 29 Class 0 and I protostars. The line profiles are very complex, showing broad emission from shocks, narrow absorption from the cold outer envelopes, and occasionally high-velocity "bullets." We interpret the spectra in the context of a new suite of evolutionary models, following changes in the chemical composition from pre-stellar cores to circumstellar disks.
