Mobile Bay
Water Quality Model Intensive Surveys Report
July 2000/May 2001
US-EPA, Region 4, SESD, Athens, Georgia
[ Full Report ]
Executive Summary
Mobile River/Bay is a 303(d) listed water body with impairment resulting from depressed dissolved oxygen (DO) levels. In addition, the State water quality criteria for DO for the Mobile River, Chickasaw Creek, and Three Mile Creek has been disapproved by EPA. As part of Total Maximum Daily Load (TMDL) development being coordinated by EPA Region 4's Water Management Division (WMD), the Science and Ecosystem Support Division (SESD) conducted two water quality studies of Mobile Bay designed specifically to provide instream data for use by WMD in development and calibration/verification of a 3-dimensional time-variable water quality model.
The first SESD Mobile Bay intensive water quality survey was conducted
in July 2000, followed by a second intensive survey in May 2001. SESD
activities focussed on water quality measurements and kinetics including
water quality sampling, oxygen/salinity profiling, reaeration, production/respiration,
and sediment oxygen demand. This report describes and summarizes the results
of the 2000 and 2001 calibration/verification surveys.
