This line shapefile was edited in ArcGIS software using the 2013 USDA-FSA Was created from the 910.0-ft contour, which is representative of normal pool elevation forД«oomer Lake. An NRCS tool developed for the ArcGIS Spatial AnalystД®xtension was used to generate contours from the lidar file.

Resources Conservation Service (NRCS) Geospatial Data Gateway website A lidar raster file (TIFFДЇormat) for the Stillwater North USGS 1:24,000 quadrangle was downloaded from the Natural The boundary for Boomer Lake was derived using 2-meter lidar data. Survey includes four steps: pre-survey planning, field survey, data processing, and model Model of the reservoir from the sorted data set. Using ArcGIS,ДЄccurate estimates of area-capacity can then be determined for the lake by building a 3-D Hypacks Sounding Selection-Sort Program using a 1 ft sort radius.

The edited data sets are then thinned to manageable sizes using During editing, data noise is removed or corrected, and depth readings areД¬onverted to elevation readings based on the daily-recorded lake level elevation on the day the The collected data files are downloaded daily from the computer and brought to the office forД®diting. On-board computer along with the positional data generated from the vessels GPS receiver. The depth readings are stored on the survey vessels As the survey vessel travels across the lakes surface, the echosounder gathers (GPS) and acoustic depth sounding technologies that are incorporated into a hydrographic The process of surveying a reservoir uses a combination of Geographic Positioning System 11-T19N-R2E.ДЇigure 1: Location map for Boomer Lake taken from Lakes of Oklahoma Water Atlas, Purposes were cooling water and recreation.
