    13Red Fish/Salt Lake mouth of Carancahua 28°37'17.62"N 96°22'47.22"WHurricane Claudette widened and deepened an existing washover into Redfish Lake. Tidal flow and wind-driven currents continue to erode , destroying emergent oyster reef (black skimmer habitat) and altering other Redfish Bay habitats. Continued erosion and uncontrolled tidal action could result in b reaching of Salt lake and furhter habitat losses. Restore protective barrier, oyster reef, marsh and sea grasses. XX
