Summary

These data were released prior to the October 1, 2016 effective date for the USGS’s policy dictating the review, approval, and release of scientific data as referenced in USGS Survey Manual Chapter 502.8 Fundamental Science Practices: Review and Approval of Scientific Data for Release.

The U.S. Geological Survey performed a bathymetric survey of Totten Reservoir using a man-operated boat-mounted multibeam echo sounder integrated with a global positioning system (GPS) and a terrestrial real-time kinematic (RTK) GPS in June 2011. The multi-beam echo sounder collected data at lake depths of approximately 3 feet and greater, whereas the terrestrial topographic survey was performed with the RTK GPS in shallow areas near the shore not navigable by boat to the elevation of the top of the dam plus about 2 to 3 additional feet. Bathymetric data from the multibeam echo sounder were collected June 6-8, 2011, and were compiled and stored using the hydrographic survey software, HYPACK 2010 from HYPACK, Inc. (HYPACK, Inc., 2010). The data were interpolated onto a 2-meter grid by computing the average of the data in each cell and positioning the mean at the cell center. The data were converted to elevation above the National Vertical Datum 1988 (Gesch and others, 2002) using reservoir stage. The bathymetry and GPS datasets were then imported into ESRI Arcmap so elevation contours could be determined. The data were used to create a Triangulate Irregular Network (TIN). This TIN was converted to a 2-meter raster dataset which was subsequently contoured. The contour lines were smoothed using a generalized 100 technique (ESRI, 2010). Some holes in the smoothed contour dataset were removed manually and some of the contours were manually adjusted to connect contours and. This created the final contour map.References:Environmental Systems Research Institute, Inc., 2010, ArcGIS—A complete integrated system: Redlands, Calif, ESRI.

Purpose

The U.S. Geological Survey, in cooperation with the Dolores Water Conservancy District, conducted a bathymetric survey of Totten Reservoir, Montezuma County, Colorado, in order to characterize the water supply capacity of the reservoir. The study was performed in June 2011 using a man-operated boat-mounted multibeam echo sounder integrated with a global positioning system and a terrestrial real-time kinematic global positioning system. The two collected datasets were merged and imported into geographic information system software. A bathymetric map of the reservoir was generated. Additionally, stage-area and stage-volumes relations were developed and plots were made.
