I consider the occurrence of the flow of accretion stream material past the edge of an accretion disk in cataclysmic variables. If the stream from the secondary star is geometrically thicker than the rim of the accretion disk, some fraction of the stream material can flow over and under the disk. The results of vertical-structure calculations for alpha-model disks indicate that the amount of overflow is a sensitive function of the general thermal state of the disk (e.g., cold and optically thick or warm and optically thin) but not of the value of the disk viscosity parameter alpha and probably not of the disk radius (i.e., the orbital period). Using the mass-transfer rates and the orbital parameters of well-studied systems, I estimate the amount of overflow for a number of individual objects and show that observationally significant stream overflow should mainly occur in quiescent dwarf novae with cold outer disks.
