Résumé :	This study examined freshwater discharge of dissolved organic matter (DOM) to the shallow Lavaca-Matagorda (LM) Bay estuarine system along the central Texas coast and investigated whether chromophoric DOM (CDOM) photochemical reactions have the potential to stimulate microbial activity within LM estuarine waters. Dissolved organic carbon (DOC) concentrations ranged from 3 to 10 mg C l(-1) and CDOM levels (reported as a (305)) ranged from 8 to 77 m(-1) during April and July, 2007, when the LM system was experiencing very high freshwater inputs. DOC and CDOM levels were well-correlated with salinities > 3, but exhibited considerable variability at salinities
