Summary

Basin boundaries were delineated for 1,320 USGS streamgages located on tributaries and streams flowing to the Gulf of Mexico. Basins ranged in size from less than 1 to approximately 67,500 square miles. Physical and climatic basin characteristics were calculated using these boundaries. Data presented here will be used as independent variables to estimate streamflow characteristics and provide a numerical foundation supporting the: (1) development of statistical models of streamflow characteristics; (2) evaluation of spatial and temporal trends in streamflow characteristics; and (3) development of network optimization analysis.

Purpose

The purpose of this data release is to present data (streamflow characteristics, basin characteristics) for 1320 USGS streamgages located in basins draining to the Gulf of Mexico. The data release is part of a USGS project evaluating streamflow alteration in the Gulf States and supports the: (1) development of statistical models of streamflow characteristics for reference and non-reference hydrologic conditions for quantifying hydrologic departure; (2) evaluation of spatial and temporal trends in streamflow characteristics and potential correlation with estuary health; and (3) development of a network optimization analysis to identify under-represented basins in the study area for potential streamgage operation.
