Individuals to contact:	RABALAIS, Nancy

Location:	Latitude: , Longitude:
General location information:	Lousiana, HAB Area code(s): US-17
Additional location information:	Lake Salvador, Lac des Allemands, Lake Cataouatche.. Low salinity lakes in the upper part of the Barataria Basin
Bloom event dates (yyyy/mm/dd):
Quarantine levels dates (yyyy/mm/dd):
Additional date-related information:	The species data below represent cell concentrations of HAB species above 10^5 cells/liter, with the exception of Prorocentrum which are reported at or above 10^4 and Anabaena spp. which are reported at or above 10^6. Cell concentrations were averaged over seven stations in these lakes for the period January to August 2005 to generate an average concentration for each species on a single sample date. Data is from surface samples collected during routine sampling and were not associated with a particular bloom event.

Causative organism known:	No
Causative Species/Genus:	Anabaena spp. (5.38x10^6 cells/L) 1/18/05 Planktolyngbya contorta (1.42x10^6 cells/L) 1/18/05
Co-Ocurring Species/Genus:
Chlorophyll concentration, if known:	µg/l
Additional bloom information:	Other species include Aphanizomenon sp., P. contorta, and Raphidiopsis curvata
