The Rivers of Central California

The central California Watershed is the largest drainage basin in California.. The USGS has created a database of this area which indicates the direction of waterflow at each point. By assembling these directions into streamflows, it is possible to trace the path of water from every point of the area to the San Pablo Bay. This animation starts with the points furthest from the bay and reveals the streams and rivers as a steady progression towards the bay until all the major rivers are revealed. The speed of the reveal of the rivers is not dependent on the actual speed of the water flow. The reveal proceeds at a constant velocity along each river path, timed so that all reveals reach the bay at the same time.
