Lower Mississippi Gulf Water Science Center

Home

Welcome to the USGS Web page that provides access to water resources information for the Lower Mississippi-Gulf. Our multi-state center spans Alabama, Arkansas, Louisiana, Mississippi and Tennessee. This is your direct link to water-resources data, quantity and quality of ground water, quantity and quality of surface water and water use. We hope you enjoy learning about water in our region!

Putting flow-ecology relationships into practice: A decision-support system to assess fish community response to water-management scenarios

This paper presents a conceptual framework to operationalize flow–ecology relationships into decision-support systems of practical use to water-resource managers, who are commonly tasked with balancing multiple competing socioeconomic and environmental priorities. We illustrate this framework with a case study, whereby fish community responses to...
