Bathymetry data from Floras Lake, Oregon, June 2018 This portion of the USGS data release presents bathymetry data collected during surveys performed in Floras Lake, Oregon in June 2018 (USGS Field Activity Number 2018-636-FA). Floras Lake is a coastal lake in southern Oregon that is separated from the Pacific Ocean by sand dunes. It is not influenced by tides, although water levels fluctuate seasonally. Lake bed bathymetry data were collected using two personal watercraft (PWCs) equipped with single-beam sonar systems and global navigation satellite system (GNSS) receivers. The sonar systems consisted of an Odom Echotrac CV-100 single-beam echosounder and 200 kHz transducer with a 9-degree beam angle. Depths from the lakebed to the echosounder were calculated using...

Lake bed backscatter data were collected using a personal watercraft (PWC) equipped with a sidescan sonar system and global navigation satellite system (GNSS) receivers. The sonar system consisted of a Tritech Starfish 990F with a 1-MHz transducer and a 0.3-degree horizontal beam width. Output from the GNSS receivers and sonar system were combined in real time on the PWC by a computer running HYPACK hydrographic survey software. Navigation information was displayed on a video monitor, allowing PWC operators to navigate along survey...
