Description

This final report is written to complete the fourth of a planned five-year study that has the goal to determine the importance of freshwater inflow in maintaining benthic productivity in minor bays and river dominated systems. Minor bays are defined as those small bays that do not have direct freshwater inflow via a major river, but do have inflow from runoff or other indirect sources. Only a few rivers in Texas flow directly into the Gulf of Mexico, and these are also part of the subject study. The current project follows successful completion of a long-term study of large, or major open bays in Texas. The focus of the current final report is on updating the long-term, five-year, monitoring of two river-dominated systems: the Rio Grande and Brazos River; and the 3-year monitoring of the Cedar Lakes and San Bernard River Estuary. In the past, assessments have been completed for the Christmas Bay Coastal Preserve (Montagna 2004), South Bay Coastal Preserve (Montagna 2003), and East Matagorda Bay (Montagna 2002). The current report goes into lesser detail for the continuing, long-term, data sets because they will be subject to a full assessment in the next fiscal year.
