Seasonal Assessment of the Relationship between the Discharge of the Trinity River and the Trinity Bay Ecosystem

Field studies of the seasonal assessment ofthe relationship between the discharges of the Trinity River and Trinity Bay ecosystem was to provide information for possible future controls in order to maintain normal biological productivity levels, botanical, zoological and water quality parameters. Overall biological productivity in a river-fed bay-type estuary is governed by a large number of environmental factors; local runoff and discharge of the river are two of the most important factors of water quality parameters. This study does not include monitoring all point sources of runoff water into Trinity Bay, so interactions of various parameters cannot be determined. Change can be clearly defined simply by relating changes observed in the bay to changes observed in the river and marshes. This study is one of three investigations concerned with Trinity drainage basin and its estuary; and , extends and supplements the previous part of this study. (Author)
