Little Bay Report Card

The Little Bay Report Card is a joint monitoring project between the City of Rockport and partners Aransas County, Aransas County Navigation District, and Mission-Aransas National Estuarine Research Reserve. The Report Card includes measurements of water quality and is based on the following parameters: temperature, salinity, dissolved oxygen, turbidity, and chlorophyll. Water quality is compared to measurements taken in Aransas Bay. This comparison with Aransas Bay will be used to provide a “grade” for each parameter and will be factored into an annual score. Aransas Bay is generally regarded as a “healthy” bay with good water quality and healthy habitats. The information provided in the reports includes a quarterly review of all water quality parameters, including nutrients. The information presented is a summary of water quality data collected by the Mission-Aransas Reserve. The Mission-Aransas Reserve manages five data-logging stations throughout the estuary and one in Little Bay. Each site contains a data logger that collects water quality information at 15 minutes intervals throughout the year. The data for five stations, not including Little Bay, are available online at
