  In this contribution we review the large body of work carried out over the
past two decades to probe the dark matter in the local universe using redshift
survey and peculiar velocity data. While redshift surveys have evolved rapidly
over the years, gathering suitable peculiar velocity data and understanding the
short-comings of different analyses have proven to be a difficult task. These
difficulties have led to conflicting results which have casted some doubts on
the usefulness of cosmic flows to constrain cosmological models. Recently,
however, a consistent picture seems to be finally emerging with various methods
of analyses applied to different data sets yielding concordant results. These
favor a low-density universe, with constraints which are in good agreement with
those obtained from LSS, high-redshift supernovae and CMB studies.
