This photo shows Howell Creek looking upstream off the East Side Road Bridge between Hopland and Ukiah. While some oaks inhabit the riparian zone on the left, the banks are mostly bare and very much at risk to erode during high flows. The braided channel here suggests high sediment supply but the stream bed has coarse material. Photo by Patrick Higgins. July 15, 2003.
This photo shows Howell Creek at the same location as Picture #1 but looking downstream. Levees line both banks, with the stream forming a featureless, linear channel. The overhead watering at left suggests some sort of riparian improvement efforts, although tree starts are not clearly visible. Photo by Patrick Higgins. July 14, 2003.
This is a closeup view of Howell Creek looking downstream off the East Side Road Bridge. The trees along the right bank appear to have been planted as at least beginning efforts at restoration. Photo by Patrick Higgins. July 15, 2003.
This photo was taken looking downstream on Mill Creek off East Side Road near Talmage Street in eastern Ukiah. The riparian zone is fragmented and the invasive, non-native giant reed (Arundo donax) grows in the foreground at right. The algae bloom may be indicative of nutrient enrichment from some source upstream. Photo by Patrick Higgins. July 15, 2003.
This photo was taken looking upstream at Mill Creek at the same location as Picture #4 and shows a step formed by large rocks and cement which may be to combat head cutting from gravel extraction in the mainstem Russian River downstream. Although the riparian includes Arundo in this view, it appears that the stream is well shaded just upstream. Photo by Patrick Higgins. July 15, 2003.
This photo shows a closeup of the pool on Mill Creek formed by the step weir at the same location as Pictures 4-5. Little young of the year steelhead darted under the cover of the algae growing in this pool. While algae may elevate dissolved oxygen in the day when it is synthesizing, it uses oxygen through respiration at night. Photo by Patrick Higgins. July 14, 2003.
This closeup view of Mill Creek shows small gravel which could be used by steelhead for spawning but poor bank structure. Photo by Patrick Higgins. July 15, 2003.
A closeup view of Mill Creek gravels shows high embeddedness with high fine sediment. Photo by Patrick Higgins. July 15, 2003.
