CH2M Hill Inc. was contracted with the California Department of Water Resources (DWR), to perform wet cross-section surveys for the Central Valley Floodplain Evaluation and Delineation Program (CVFED) upper Sacramento River topography data collection area. The purpose of these surveys were to provide data to the CVFED Program for hydraulic modeling task orders.
The associated data are considered DWR enterprise GIS data, which meet all appropriate requirements of the DWR Spatial Data Standards, specifically the DWR Spatial Data Standard version 3.5, dated April 12, 2023. DWR makes no warranties or guarantees — either expressed or implied — as to the completeness, accuracy, or correctness of the data. DWR neither accepts nor assumes liability arising from or for any incorrect, incomplete, or misleading subject data. Comments, problems, improvements, updates, or suggestions should be forwarded to gis@water.ca.gov.
<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>This version of metadata is an interim metadata submittal. The data coverage for this submittal includes the wet section surveys for Knights Landing Ridge Cut and the Colusa Drain Connector and ends west of Grays Bend, roughly 4 miles to the south of Knights Landing. The bounding horizontal coordinates (in decimal degrees) for this submittal are as follows: West: -121.729018, East: -121.692621, North: 38.801925, South: 38.749172. Wet cross-section field surveys were performed using GPS and conventional total station surveys to collect channel geometry for stream areas that were under water during the Light Detection and Ranging (LiDAR) data capture. This work was done for the California Department of Water Resources, Division of Flood Management. The data were collected in NAD83 and NAVD88 datums (vertical and horizontal units in feet).</SPAN></P></DIV></DIV></DIV>
