Estero Bay is a shallow estuary, across which salinity gradients from freshwater to saltwater occur over short land-sea distances. Such gradient compressions can result in a highly variable salinity environment and affect a diverse range of estuarine flora and fauna when even a small change in watershed runoff occurs. Rapid development within the bay's watershed has a changing effect on the amount, timing, and quality of runoff into the bay. Currently there is no information available to assess the effect that these alterations of runoff may have on the bay and its biota, nor to define watershed runoff and loading limits that provide desirable ranges in salinity and water quality at historical, current, and potential locations for seagrass, oysters, and other species of concern. To manage and preserve the Estero Bay ecosystem, it is necessary to: (1) understand the salinity patterns of the bay in relation to freshwater inflow and water exchange with the Gulf of Mexico; (2) describe the mixing and freshwater residence times within the bay; and (3) study the effects on light penetration from increased Total Suspended-Solids (TSS) load and re-suspension. Results from this study will facilitate management decisions geared toward defining flow and sediment loading limits that provide desirable ranges in salinity and water quality by providing necessary hydrological information.To carry out the objectives of the study, a network of monitoring stations will be established and will include: (1) the monitoring of flow, water level, salinity, temperature, Acoustic Backscatter Strength (ABS), and turbidity near the mouth of three of four tributaries flowing into Estero Bay; (2) monitoring of water level, salinity, temperature, turbidity, wind speed and direction, and barometric pressure at one location inside the bay; (3) monitoring of water level, flow, salinity, temperature, and ABS at three of four tidal exchange points with the Gulf of Mexico along the barrier islands; (4) monitoring of water level (depth), salinity and temperature at one open-water location in the Gulf of Mexico.
Water samples for TSS and SSC analyses will be collected near the mouth of the three tributaries flowing into Estero Bay. Both laboratory analyses will be done with duplicate samples in order to address possible bias as described in WRI 00-4191. Continuous ABS and turbidity data will be collected at the three tributary sites and regression analyses will be used to determine if correlation can be obtained and time-series records of TSS concentrations produced.

Stage, discharge, salinity and temperature were collected at Big Carlos, Big Hickory, Estero River near mouth, Imperial River, and Matanzas Pass Bridge for 2002-2005.
Salinity and temperature were collected at Cow Creek for 2003 and at Fishtrap Bay near Bonita Beach for 2002-2005.
Stage, salinity, and temperature were collected at Boundary site-Matanzas Pass at Pass marker 1 for 2002-2004 and at Mullock Creek near mouth for 2002-2005.
Stage, salinity, temperature, and wind speed and direction were collected at Estero Bay near Horseshoe Keys for 2002-2005.
Salinity and temperature were collected for all stations. Stage, discharge, and wind information were collected in addition at some stations
All monitoring was done according to USGS protocol, methods, and techniques. Flow monitoring stations were equipped with acoustic instrumentation for the measurement of water velocity and an Acoustic Doppler Current Profiler was used for discharge calibrations during different hydrologic and tide conditions.
