Abstract

Fifty-four major streams discharging directly to the Gulf of Mexico and having drainage areas exceeding 200 square miles have been identified in the United States. Periods of record for daily values of streamflow and water quality are summarized for the lower reaches of each of these streams. Forty-four U.S. Geological Survey streamflow-gaging stations along the Gulf Coast with at least 40 years of daily streamflow data also were identified. These stations include most of the major streams and comprise 95 percent of the drainage area to the Gulf from the United States. Temporal trends are determined for daily mean streamflow for selected long-term stations for each of three streamflow perspectives: mean, minimum daily mean, and maximum daily mean. Distributions of monthly streamflow are determined for each of the 44 long-term stations. Temporal trends in streamflow and variations in monthly streamflow distributions are related to factors that affect streamflow: precipitation, land use, with- drawals, reservoir operations, and other factors. Trends in streamflow and variations in streamflow distributions at many stations are coincident with expected changes in streamflow caused by these factors.
