The number of known halo streams has increased dramatically with the advent of deep, well-calibrated, wide-area sky surveys. Twenty nearby halo streams have been discovered to date, a number that is likely to at least double as surveys of the southern hemisphere progress. By themselves these streams tell us something about the accretion and disruption history of stellar aggregates in our Galaxy. More importantly, they will ultimately enable us to put much tighter constraints on the three dimensional shape of the Galactic potential. The morphologies of cold streams may also help us to constrain the occurrence and mass function of a predicted population of dark matter subhalos. We tabulate some basic properties of the known nearby streams, and discuss prospects for future discoveries.
