Meta Identifier	GMA_trinSSA
Type of Data	Sediment Budget parameters including: hydrology, sediment sources, sediment transport
Originator	Graham Matthews and Associates
Description	In October 1999, Graham Matthews & Associates was requested by the U.S. Environmental Protection Agency (EPA) and Tetra Tech, Inc., to prepare a sediment source analysis and preliminary sediment budget for the mainstem Trinity River watershed. This study compiles, summarizes, and analyzes sediment production data for the Trinity River watershed that could be used for TMDL development.

Purpose	The purpose of this study was to prepare a sediment source analysis and preliminary sediment budget is to assist the EPA in establishing a Total Maximum Daily Load (TMDL) for sediment in the mainstem Trinity River watershed.
Data Quality Information	Data are high quality
Use Constraints	none
Supplemental Information	The largest tributary of the Trinity River, the South Fork Trinity River, had a separate TMDL prepared in 1998 (USEPA 1998).
