The most important problem for the watershed is excessive erosion. The area has a high degree of natural erosion because of uplift and displacement caused by the San Andreas Fault, which runs through the area. However, logging and roads have greatly increased the amount of sedimentation in the river. Kelly Road, which runs between Lake Sonoma and Annapolis, California, is a major source of sediment in the river and its tributaries. High water temperatures is another significant problem. Logging has removed large streamside trees that provided shade and reduced the amount of large woody debris, which creates pools.
