This photo shows the early morning application of pesticides on a vineyard. The effect of pesticide use on aquatic systems in the Russian River basin is not well studied. Photo by Patrick Higgins. July 15, 2003.

This closeup shows vineyards off Alexander Valley Road growing right up next to the back side of the Russian River riparian zone just past the bridge looking southwest. Photo by Patrick Higgins. July 15, 2003.
Vineyard access road runs right up against the Sausal Creek riparian zone with little filter capacity left ot help trap eroded soils coming from the road or fields. Photo by Patrick Higgins. July 15, 2003.
This photo was taken looking west off Red Winery Road at vineyards stretching across Anderson Valley. Photo by Patrick Higgins. July 15, 2003.
This ephemeral channel off Red winery Road in the Alexander valley drains a reservoir just out of view to the right (see Picture #7). The steps in the channel are likely designed to prevent gullying. Photo by Patrick Higgins. July 15, 2003.
This photo shows the concrete apron of the drain for a reservoir constructed to retain winter rains for watering grapes. The overflow during rainy periods would wash down the apron. Rock has been placed here to decrease erosion. Photo by Patrick Higgins. July 15, 2003.
This beautiful shot of vineyards against a backdrop of native California oak woodlands and grasslands was taken just off Red Winery Road. The question of how conversion of wildlands to vineyards affects flows and water quality is not yet well studied in the Russian River basin. Photo by Patrick Higgins. July 15, 2003.
