Freshwater Flows Into Northeastern Florida Bay
and Flow Exchange in Florida Bay Channels
OBJECTIVES• Collect continuous stage, velocity and salinity data at major creeks flowing into
northeastern Florida Bay
• Compute discharge at creeks and study the quantity, timing and distribution of that flow
Why is Flow-Salinity-Water level Information Needed?
• Accurate flow information is needed to help understand the circulation, mixing, and salinity dynamics of Florida Bay and the Everglades
• Quantify nutrient, sediment, and biological fluxes
• Flow, stage, and salinity data help verify inland simulations of marsh-flow dynamics
• Evaluate performance of management practices
Overview• Study area
– Monitoring station descriptions
• Quantity, Timing and Distribution– Methods of acoustic flow measurements– Data from creek monitoring sites– Flow characteristics
• CERP/GEER Integration • Collaboration/Data users• Florida Bay Flow Exchange-• Pink Shrimp Studies

CERP INTEGRATION• The principal goal of restoration • “ to deliver the right amount of water, of
the right quality, to the right places, and at the right time.”

Monitoring Flow, Stage, and Salinity in Florida Bay Channels
OBJECTIVES
• Collect continuous stage, velocity and salinity data at six major channels in Florida Bay
• Compute discharge within the channels and study the quantity, timing and distribution of that flow
• Help quantify postlarval Pink Shrimp movement into and out of Florida Bay
