Salinity throughout the estuary increased slightly last week, except at A1A Bridge which had a slight decrease. At both the Roosevelt and A1A Bridges, weekly average salinity is slightly above the upper bound of the preferred range. Salinity conditions in the estuary are considered to be fair considering the time of year, the location in the estuary, and salinity preference of the oyster, Crassostrea virginica.
Caloosahatchee Estuary
Current Conditions:
During the past week, no discharge occurred at S-79. Discharge averaged 128 cfs at S-78, while discharge at S-77 was unavailable. The concentration of chlorides at the Olga Plant was 157 ppm on Sunday. The current weekly average salinities (in bold) at the six monitoring sites in the Caloosahatchee Estuary are given below in parts per thousand (ppt), along with the previous week’s (in parenthesis).
