摘要: |
The Bureau of Reclamation (Reclamation) surveyed Harry Strunk Lake in May 2006 to develop new reservoir topography and compute storage-elevation relationship (area-capacity tables). The 2006 underwater survey, conducted between reservoir elevation 2,365.7 and 2,365.9 feet (project datum), used sonic depth recording equipment interfaced with a real-Time kinematic (RTK) global positioning system (GPS) that gave continuous sounding positions throughout the underwater portion of the reservoir covered by the survey vessel. Above-water topography was mapped by digitizing a reservoir contour from the U.S. Geological Survey quadrangle (USGS quad) maps of the reservoir area. Using the 2006 survey data, the digitized contour was adjusted throughout the reservoir due to shoreline erosion and in the upper reservoir area due to the sediment delta. Due to the lack of above water data, this study assumed no change since the 1981 range line survey from elevation 2,366.1 and above. / Availability Note: Order this product from NTIS by: phone at 1-800-553-NTIS (U.S. customers); (703)605-6000 (other countries); fax at (703)605-6900; and email at orders@ntis.gov.
