Those drainage patterns are just the general patterns that you're likely to encounter anywhere, not just in California. Dendritic is flow on relatively uniform flat areas, parallel is flow on relatively uniform sloping areas, trellis is flow on undulating terrain (usually old ones that cross over the ranges of hills), rectangular is incised jointing in large blocks, annular is flow around a hill in the middle of a parallel pattern, and radial is flow down from a hill onto a relatively flat area. A distributary is something else entirely and only happens at the outlet of fairly large rivers (they are comparatively tiny when held against most of the other flow patterns and certainly tiny compared to the river's overall length). Distributaries have the delightful property that they're constantly changing as the individual channels silt up and move unless herculean efforts are expended to force the pattern to remain the same. Those efforts invariably cause all manner of problems in the long term (see the Mississippi delta).
For a volcanic island, radial is the most likely pattern of flow that you'll encounter because it's all downhill from the top. A compound volcano like the big island of Hawaii is likely to have some small areas with parallel drainage because the cones can coalesce into a relatively flat slope (see the rivers on the big island's north side).
