We present results of an H_2 imaging survey of the Rho Ophiuchi proto-cluster to search for near-IR HH/jets associated with the forming stars in the cloud. The observations were carried with SOFI (Son of ISAAC) at the ESO NTT. We covered an area of roughly 30 x 30 arcmin on the cloud. This region was observed in both the H_2 (2.12 micron) and the H_cont (2.09 micron), the continuum nearby, filters. HH/jets clearly show up in the H_2 images (the line emission) and disappear in the adjacent continuum. We have detected about 20 new near-IR HH/jets of different morphologies in the region emanating from the Class 0-I young stars in the cloud. However an unique and definitive identification of the driving source of each flow is not possible as several extremely young stars lie within a few arc-minutes of the positions of the structures found in H_2.
