Gulf of Mexico Flows

1 Gulf North

1a Tennessee River Watershed

The Tennessee River collects rainfall and runoff for the Ohio River system, which joins the Mississippi and empties out into the Gulf of Mexico.  While no part of the Tennessee River itself passes through Georgia, there are tributary creeks originating in north Georgia that cross the state line and join up with Tennessee waters.

Lookout Creek drains an area of 149 sq miles of Dade County.  The flow is monitored near New England: normal flow at this station is around 280 cfs and 5.4 ft deep. Minor flooding occurs at 12 feet.

Chattanooga Creek drains an area of 6 sq miles of Walker County.  The flow is monitored at Flintstone, has been around 80 cfs and 4.5 ft deep.

West Chickamauga Creek drains an area of 148 sq miles in Catoosa County.  The flow is monitored near Lakeview: has been around 250 cfs and close to 3 ft deep.

South Chickamauga Creek drains an area of 169 sq miles in Catoosa County.  The flow is monitored near Ringgold: has been measured in this location at around 250 cfs and 5 ft deep. (04-18-23)

1b Coosa River Watershed

The Coosa River is a collection of several tributary rivers gathered from northwest Georgia.  At the beginnings of this system, the Conasauga River and Coosawattee Rivers join up to form the Oostanaula River.  The Oostanaula in turn joins flow with Etowah River system to form the Coosa River.  The Coosa runs west into Alabama where it merges with the Tallapoosa River across the state line in Alabama, forming the Alabama River, eventually reaching the Gulf of Mexico.

Flows

WTGA describes the stream flows in each watershed, including direction/path of flow, listing monitoring stations in order from headwaters to outlet, indicating the seasonal normal flow volume in cubic feet per second (cfs), the gage height (flow depth) during normal conditions and the flood stages, or the gage height at which flooding will occur.  Locate your “home body” (the river or stream nearest you) to see where the flow originates, how high the flow must be for minor flooding to occur.  Log in to USGS Waterwatch current streamflow for real time measurements at the monitoring station nearest you and sign up there for high flow alerts.

Flow volume can change rapidly during rain events, check your local upstream station flow levels at the USGS WaterWatch Current Streamflow site, or sign up for high flow alerts to your mobile device.  Streamflow data is subject to review as sensors at the monitoring stations do malfunction from time to time. See USGS Provisional Data Statement at the end of this report for more information.

EPA Impaired Water Bodies 303d List

The EPA requires all states update a draft list of impaired water bodies (the 303d list) every two years; providing a period for public comments, presenting the draft list to the EPA.  The final 303d list is published as approved by the EPA, roughly every two years.

Impaired water bodies are defined as those with contaminants measured above threshold levels, as set by the EPA Clean Water Act, or where the desired use is impaired.  The 2020-2022 Draft list includes Georgia lakes, creeks, rivers and reservoirs that recommended for Total Maximum Daily Load (TMDL) plans.  The TMDL plan is a type of Clean Water Plan, established by a collaboration of municipal, industrial and environmental groups in an overlay zoning district.

Reporting from the latest records uploaded to the Georgia spill incidents database

Spills of petroleum products of 40 gallons or more are listed weekly in the watershed in which they occur, citing location of the spill, the contaminant spilled (if known), the quantity (if known) and the resource affected (if known) surface water, groundwater, sewer, etc, and any amounts recovered at the site. 

Spills over 100 gal, very toxic chemical spills and spills that impact state waters are flagged and followed up with the spiller, the state and/or EPA authorities for more information, these are marked with asterisk.*

See Spills Tracker for more information on these spills as it becomes available.
