USACE Levees This map file displays riprap and levees installed by the U.S. Army Corps of Engineers between 1963 & 1983. Additionally, it maps the river banks of the Sacramento River, the State Maintenance Area, and the levees of the Sacramento River Flood Control Project.

Bank Protection - Reach 3 This dataset was compiled from an inventory and mapping of riprap along reach 3 of the Sacramento River (River Mile 194 at Chico Landing to River Mile 143.5 near Colusa) by the the Environmental Services Section, California Department of Water Resources (DWR), Northern District in 2000. Riprap was defined as rock, cobble, concrete rubble, or other hard material placed to reduce erosion from flowing water.

River Miles This dataset is a point coverage that identifies river mile markers along the Sacramento River. The river mile markers are a commonly-used reference system for discussing areas and locations along the River. This particular dataset is from the Army Corps of Engineers river miles from the 1991 Army Corps of Engineers Sacramento River Atlas.

Inner River Zone The Inner River Zone is the area along the Sacramento River that has been determined to be the most prone to channel movement and flooding. Reaches 1 & 2 were defined by combining the past 100 year meanderbelt with projected erosion locations 50 yearsin the future, while boundaries in reaches 3 & 4 were influenced by existing flood control structures. It should be noted that the boundary is only a guideline, as its location will be influenced by several factors: voluntary participation by public and private landowners, unexpected changes in channel alignment, and individual decisions to install bank protection.

Historic River Channel Locations between the years 1896 and 1997 This dataset consists of historic Sacramento River channels of selected years between 1896 and 1997. The following years were digitized from the sources cited in the 'Creation Info' section of the metadata document : 1896, 1908, 1923, 1935, 1937, 1946, 1955, 1956, 1960, 1964, 1969, 1976, 1981, 1991, and 1997. Since the channel locations were mapped at different times using different techniques, sources, and source scales, the quality varies. Generally, the more recent channel location information is more accurate.

100-year Meander Belt The 100-year meanderbelt is the combination of all channel locations between 1896 and 1991. In other words, it is that area along the river that has experienced channel movement in the immediate past.

Sacramento River Conservation Area The 222 miles of the Sacramento River and the adjacent 213,000 acres of land extending from Keswick Dam in Shasta County south to the town of Verona in Sutter County; the area is targeted for preservation of existing riparian habitat as well as restoration of previous zones of riparian habitat.

Reaches within the Sacramento River Conservation Area The Sacramento River Conservation Area has been divided into four broad reaches: Keswick Dam to Red Bluff, Red Bluff to Chico Landing, Chico Landing to Colusa, and Colusa to Verona. Each of these reaches has unique characteristics, such as extent of native riparian vegetation, geology, levees, etc., that require slightly different priorities for restoration purposes. Each of the four reaches is briefly described below; however, these reaches as well as restoration strategies for each, are discussed in greater detail in the Sacramento River Conservation Area Handbook (Chapters 5-8.)

Recent alluvial deposition along the Sacramento River Unweathered gravel, sand, and silt deposited by present-day stream and river system that drain the Coast Ranges, Klamath Mountains, and the Sierra Nevada. Differentiated from older stream-channel deposits (Qao and Qal) by position in modern channels. These units lie outboard of unit Qsc but inside the first low terraces flanking modern stream channels. The deposits from levees along the main course of the Sacramento River, and broad alluvial fans of low surface relief along the western and southwestern side of the valley. Because of high organic content, the levee deposits are darker gray than the alluvium flanking the channels on smaler streams. Thickness varies from a few centimeters, to 10 meters.

Riparian Vegetation along the Sacramento River, 1999 This SRRM99 effort is an update to the Sacramento River Riparian Mapping Project that was started in 1991 and completed in 1998. This project, however, was confined to the mainstem of the Sacramento River between Colusa on the south and Keswick Dam to the north. It is located in the Sacramento River Conservation Area (SRCA) approximately between River Mile 129 and RM 300.

The mapping was completed in 2002 using aerial photography taken in 1999 for the Sacramento River Comprehensive Study. The airphotos were flown at the nominal scale of RF=1:7200 (1 inch = 600 feet)
