“…Reach 1 occurs entirely within the Central Valley and has a large, contiguous floodplain separated from the Sacramento River only by natural levees (and occasional riprap). Flood flow, although reduced by Shasta Dam, frequently overtops the natural levees composed of finer sands, silts, and clays [Brice, 1977;WET, 1990] and causes extensive overbank sedimentation [Blodgett, 1971[Blodgett, , 1981. In addition to vertical accretion, lateral floodplain accretion is apparent in this reach in numerous, large sand bars.…”

Abstract. Spatial patterns in suspended sediment transport and storage along the Sacramento River were assessed by evaluating the suspended sediment budget for the main channel accounting for all tributaries and diversions. Time series analysis was employed to quantify the relationship between streamflow and suspended sediment concentration for gauging stations along the main channel and signature tributaries. Sediment concentration records (of 2-yr duration) were extended using Box-Jenkins transfer function models to calculate annual rates of suspended sediment discharge over a 32-year period since dam construction on the Sacramento River. The suspended sediment budget was evaluated to identify reaches of net erosion or deposition. The results of the budget suggest the influence of tectonics and anthropogenic channel modifiLation.

“…Overland flow in Butte Basin was about one-third of the total peak flow of 225,000 ft3/s measured at the latitude of Butte City on January 24, 1970 (Blodgett and Pearce, 1971). Because most bridges on State Highway 162 in Butte Basin lack the capacity to convey floods, excess floodflows cross the highway between bridges at eleven sites.…”

Floodflows and peak stages of floods were measured and channel cross sections were surveyed at sites along the Sacramento River and in Butte Basin, Sacramento Valley, California, during 1980-90 to document magnitudes of flooding and channel changes. The study reach extends from rivermile 200 near Hamilton City to rivermile 134 near Meridian. Data were collected for each flood at about 70 sites that include streamflow gages, crest-stage gages, bridges and road overflows on State Highway 162 east of Butte City, and locations of historical high-water marks. Six cross sections of the river between rivermiles 193.7 near Big Chico Creek and 183.3 near Ordbend were surveyed annually during calendar years 1981-84 and 1986-90. Floodflows (peak flow 157,000 cubic feet per second) almost equaled the design flow capacity of the river at Butte City on March 2, 1983, when the peak stage of 93.0 feet was 5 feet below the top of the levee. This was the largest flood recorded at Butte City during 1980-90. The most recent flood occurred February 18-19, 1986, when the peak stage in the river at Butte City was 92.0 feet and the peak flow was 145,000 cubic feet per second. Butte Basin is an agricultural area on the flood plain east of the Sacramento River (fig. 1) between Big Chico Creek and Meridian. Rice is the principal crop, but orchards and row crops also are cultivated in the area. Much of the basin is a waterfowl-wintering area that is enhanced by flooding. Changes in the distribution of flows across the flood plain are caused by farming activities, growth or clearing of vegetation, and roadway and bridge construction (Blodgett and Stiehr, 1974). During periods of flooding on the Sacramento River between Big Chico Creek and Meridian (fig. 1), flows inundate Butte Basin. Levees on the left (east) bank of the river downstream from rivermile 176 near Glenn prevent flooding into Butte Basin; however,
