About this file
This document contains hydrographic survey data and cross-sectional profiles for Tiger Pass in Venice, Louisiana. The U.S. Army Corps of Engineers New Orleans District conducted a multibeam sonar survey in September 2019 to map the channel bottom and adjacent areas. Cross sections depict existing and proposed channel depths of -9.67 feet and -10.67 feet mean low Gulf. Computed dredge volumes to these depths are 2,762 cubic yards and 3,777 cubic yards respectively. A related federal contract opportunity posted by the U.S. Coast Guard seeks dredging of the U.S. Coast Guard Station Venice boat basin. The solicitation number is 70Z08221BPMW00100 but additional details on required work, response dates, or award timing are not provided in the appendices.

Vertical Datum:
Soundings are shown in feet and indicate depths below Mean Low Gulf Datum (MLLW).
Datum relationship at Venice - 01480:
0.0' MLLW (2002-2006) = 0.3' NAVD88 (2009.55)
Distances on Tiger Pass are shown at 1 mile intervals.
The location of navigation aids are base on and provided by the U.S. Coast Guard.

** Shoalest Sounding per Quarter per Reach.
*** High frequency (200 kHz) survey data represents the first signal return at a sounding location and will include suspended solids, known as "fluff", if present. Low frequency (20 kHz) survey data normally penetrates through this "fluff" layer to depict elevations of consoldiated bottom material. Low frequency accuracies may vary depending on channel conditions and fathometer settings.
