Average salinity increased at
both the Roosevelt and A1A Bridges last week.
Only bottom water at the A1A Bridge fell within the preferred

salinity conditions in the estuary are poor to fair (see attached).

Discharge at S-79 averaged 53
cfs over the past week. The concentration of

throughout the upper estuary last week but changed little at
