MonitoringLocationDescriptionText Redwood Valley Road crosses the creek 5.5 miles from Highway 299. Toss Up Creek borders this unnamed creek to the south; Mill Creek borders to the North. The creek was surveyed from its confluence with Redwood Creek to a point 0.75 miles upstream. The creek's mouth lies in dry, open, flatland. It starts climbing steadily after the first 100 yards. The lower 100 yards of the stream is full of green filamentous algae which disappears as the overhead canopy increases upstream. The stream is littered with logging debris and landslides. The immediate drainage basin is 0.81 square miles. At the time of sampling the entire drainage basin was owned by Barnum Timber.
