Book excerpt: Excerpt from Surface Water Flow: For 1957 This stream gaging station, located on the left bank and 300 feet upstream from the "I" Street Bridge, is an important station within the Federal-State network of stream gaging stations dating back to November 1879 when the U. S. Weather Bureau reported gage heights only. This station contains a water stage recorder which provides a continuous record of the water surface elevation (stage). The station is the lowest water flow measuring point on the Sacramento River before the river discharges into the Pacific Ocean. The maximum discharge for this station occurred on November 21, 1950, with a stage of 30.14 feet and a discharge of 104,000 cubic feet per second. On January 9, 1957, a telemark was installed with the recorder for transmitting Instantaneous coded stage readings over a standard telephone circuit by dialing an assigned number. During flow periods when the river discharge drops below approximately 35,000 cubic feet per second, the flow is affected by tidal influence which requires periodic tidal cycle measurements (generally monthly) with special computational procedures. During these periods personnel from both the Department of Water Resources and the U. S. Geological Survey cooperate in making a tidal cycle measurement. One measurement is made approximately each hour and 20 minutes throughout a 36-hour period, covering two and one-half tides. Four to five men usually work one or two of four nine-hour shifts, using an l8-foot outboard with a 30 horsepower motor as pictured above. Two patrol boats are also used, one upstream and one downstream from the station, to warn river traffic and to aid in raising and lowering the tag line (a steel cable, marked with regular stationing and fastened to a power winch, stretched across the 600-foot wide stream) so that traffic may pass. Flows above 35,000 cubic feet per second are measured in the conventional manner using a stage-discharge relationship.
