Notice the high water level in the channel as a result of the closed sand spit at the mouth of the river. See Cannata 2001 for information on habitat values of the estuary.

Notice large pale patches of unvegetated sand bars filling channel. Disturbance on the bar downstream of the crossing suggests equipment has been used to grade the bar or extract gravel.

The main channel of the Navarro River is visible flowing through the center of the photo. The river bar here shows major signs of aggradation, with the thread of wetted channel very small in comparison to the wide gravel bar. Photo by Rixanne Wehren, August, 2001.

The main channel is visible in the foreground, with a thin, watered channel moving through the sediment choked channel. Notice the lack of vegetation on the near side of the channel bank. In the background is Duckhorn Vineyards pond development on the right. On the left and center are similar vineyard developments. Photo by Rixanne Wehren, August, 2001.

The scale of the project is visible when comparing the size of the earth movers in the center of the photograph to the size of the pond. The Navarro River passes below the view of the photo.

Notice large pale patches of fine sediment filling channel devoid of vegetation. The aggradation causes the channel to be wide and the river to be shallow which facilitates stream warming.

Although riparian vegetation has been retained along the immediate wetted channel, there is no gallery forest or overstory. The river is almost losing surface flow here as a result of aggradation and possibly flow diversions. Photo by Rixanne Wehren, August, 2001.
