This closeup view of the Dry Creek terrace shows fine sediment deposited in the margins of the stream and very small particle size distribution. Coarse aggregate is greatly reduced by Warm Springs Dam, but there is a fine sediment source of some origin. Photo by Patrick Higgins, January 18, 2003.

This picture shows the riparian zone of Dry Creek with Arundo donax, the giant reed competing with hardwoods. The giant reed retains its foliage in winter, giving it a competitive advantage over the hardwoods, which are deciduous. Photo by Patrick Higgins, January 18, 2003.

This picture shows a closeup of the patch of giant reed, shown in Picture #4. Arundo is not native to the Russian River basin but competes well in disturbed environments. Since the reed spreads with rhizomes, it is very difficult to eradicate once established. Photo by Patrick Higgins, January 18, 2003.

This shot shows vineyards in the Dry Creek valley looking back toward the stream. The tall trees are the riparian zone of Dry Creek. Grass under the grape vines and the flat terrain, help minimize surface erosion from the vineyard depicted. Photo by Patrick Higgins, January 18, 2003.

This photo shows vineyards in Dry Creek valley looking west toward the coast. The part of the vineyard in the distance is on a mild slope, but some vineyards in the Dry Creek basin are on steeper slopes, which pose greater erosion control challenges. Photo by Patrick Higgins, January 18, 2003.
