    • Topographic survey data of Oxbow Reservoir, Placer County, California, October 2022

    Metadata Updated: July 6, 2024

    This portion of the data release presents topographic survey data of portions of Oxbow Reservoir in Placer County, California. These data were collected on 26 October 2022, when the reservoir was partially de-watered to allow repairs to the dam infrastructure following the Mosquito Fire. Although the gates of the dam were open during this time, significant portions of the reservoir site remained inaccessible to surveyors due to the continued flow of the Middle Fork American River. Consequently, these data cover approximately 50 percent of the total surface area of the reservoir at full pool. The data were collected using two RTK GNSS backpack rovers which were referenced to a temporary GNSS base station occupying a fixed control point ("CP512") located less than 1 kilometer from the survey area. Precise coordinates for the GNSS base station were derived using the National Geodetic Survey (NGS) Online Positioning User Service (OPUS). The GNSS data are presented as a comma-delimited text file.
