    dct:description """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
