It is now known that all young stellar objects pass through an outflow phase, that outflow power is regulated by infall rate in protostars, and that jet launching and disk accretion are intimately related phenomena. Not yet known is at what evolutionary stage outflows cease, how disk dissipation timescales are related to outflows, and the relation between outflow and disk evolution. We have recently conducted a survey of the Rho Ophiuchi molecular cloud for the presence of outflows via narrowband H2, Brackett Gamma, and K-band continuum mapping at the Anglo Australian Telescope and Palomar Observatory. Our survey has 5 times better sensitivity than those previously completed at these wavelengths. Our primary scientific goals are: 1. To obtain an inventory of outflows within the cloud, and 2. To quantitatively explore the relationship between disk and outflow properties. In this contribution, we present the preliminary results of our survey.
