Date: Fri, 31 Aug 2012 10:55:03 EDT

Summary: LAWSC Flooding Impacts and Activites

For gages located within the Florida Parishes of Louisiana, the rainfall of 10 to 16 inches was recorded. The WaterWatch map shows multiple gages within the Florida Parishs above flood stage. Two crew of four are deployed to measure the Bogue Chitto, Tchefuncte, Tangipahoa, Tickfaw, Natabany Rivers. Time permitting, the Amite and Comite Rivers will be measured. The Amite River at Denham Springs (07378500), and Port Vincent (07380120) have Web Cameras; the links provided below.

Hydrographs of Florida Parish streams indicate flood waters are receeding; including the northern most gages along the Tangipahoa River near Percy Qinn State Park. The Lower Mississippi River Forcast Center link is provided below which forcasts stages for these gages.

Within the Breton Sound Basin, 5 of the 7 gages were damaged and are inoperable from Hurricane Isaac. The only two operable gages were flood hardened. NE Bay Gardene near Point-A-La-Hache (07374527) recorded the storm surge of over 12 feet. Within the Barataria Basin, three gages were damaged by flooding.

Tomorrow, (9/1/2012) The LAWSC and the National Wetlands Research Center personnel will meet, corrdinate, and begin storm surge sensor retrieval and the flagging high water marks. We will run RTK levels using the LSU Gulfnet system.
