We present the survey of ^12^CO/^13^CO/C^18^O (J=1-0) toward the California molecular cloud (CMC) within the region of 161.75{deg}<=l<=167.75{deg}, -9.5{deg}<=b<=-7.5{deg} using the Purple Mountain Observatory (PMO) 13.7m millimeter telescope. Adopting a distance of 470pc, the mass of the observed molecular cloud estimated from ^12^CO, ^13^CO, and C^18^O is about 2.59x10^4^, 0.85x10^4^, and 0.09x10^4^M_{sun}, respectively. A large-scale continuous filament extending about 72pc is revealed from the ^13^CO images. A systematic velocity gradient perpendicular to the major axis appears and is measured to be ~0.82km/s/pc. The kinematics along the filament shows an oscillation pattern with a fragmentation wavelength of ~2.3pc and velocity amplitude of ~0.92km/s, which may be related to core-forming flows. Furthermore, assuming an inclination angle to the plane of the sky of 45{deg}, the estimated average accretion rate is ~101M{sun}/Myr for the cluster LkH{alpha} 101 and ~21M{sun}_/Myr for the other regions. In the C^18^O observations, the large-scale filament could be resolved into multiple substructures, and their dynamics are consistent with the scenario of filament formation from converging flows. Approximately 225 C^18^O cores are extracted, of which 181 are starless cores. Roughly 37% (67/181) of the starless cores have {alpha}vir less than 1. Twenty outflow candidates are identified along the filament. Our results indicate active early-phase star formation along the large-scale filament in the CMC region.
