Presented below are water quality standards that are in effect for Clean Water Act purposes. EPA is posting these standards as a convenience to users and has made a reasonable effort to assure their accuracy. Additionally, EPA has made a reasonable effort to identify parts of the standards that are not approved, disapproved, or are otherwise not in effect for Clean Water Act purposes. Rule 391-3-6-.03. Water Use Classifications and Water Quality Standards ( 1) Purpose. The establishment of water quality standards. (2) W ate r Quality Enhancement: (a) The purposes and intent of the State in establishing Water Quality Standards are to provide enhancement of water quality and prevention of pollution; to protect the public health or welfare in accordance with the public interest for drinking water supplies, conservation of fish, wildlife and other beneficial aquatic life, and agricultural, industrial, recreational, and other reasonable and necessary uses and to maintain and improve the biological integrity of the waters of the State. ( b) The following paragraphs describe the three tiers of the State's waters. (i) Tier 1 - Existing instream water uses and the level of water quality necessary to protect the existing uses shall be maintained and protected. (ii) Tier 2 - Where the quality of the waters exceed levels necessary to support propagation of fish, shellfish, and wildlife and recreation in and on the water, that quality shall be maintained and protected unless the division finds, after full satisfaction of the intergovernmental coordination and public participation provisions of the division's continuing planning process, that allowing lower water quality is necessary to accommodate important economic or social development in the area in which the waters are located. -

It rained on us a couple of times, but the paddling kept us warm. We passed empty golf courses and leafless trees. We did see several herons and a couple of raptors hunting the river. Bobby Marie 1/14/2012 – Etowah, Coosa, Oostanala Rivers On January 14th, I joined Joe Cook and about 100 others on the CRBI Polar Bear Paddle over by Rome, GA. In one day I paddled 3 rivers, the Etowah for the major portion of the trip, then took two side paddles, upstream on the Oostanala for 30 minutes and then down and back up the Coosa for 30 minutes. When you reach the confluence of these three rivers you can look down and see the difference in the waters. The Etowah was greenish and the Oostanala was very brown and the Coosa was a mixture of the two! I only saw one BIG cooter on the bank in the sun the whole day. -

Streamflow Maps of Georgia's Major Rivers
GEORGIA STATE DIVISION OF CONSERVATION DEPARTMENT OF MINES, MINING AND GEOLOGY GARLAND PEYTON, Director THE GEOLOGICAL SURVEY Information Circular 21 STREAMFLOW MAPS OF GEORGIA'S MAJOR RIVERS by M. T. Thomson United States Geological Survey Prepared cooperatively by the Geological Survey, United States Department of the Interior, Washington, D. C. ATLANTA 1960 STREAMFLOW MAPS OF GEORGIA'S MAJOR RIVERS by M. T. Thomson Maps are commonly used to show the approximate rates of flow at all localities along the river systems. In addition to average flow, this collection of streamflow maps of Georgia's major rivers shows features such as low flows, flood flows, storage requirements, water power, the effects of storage reservoirs and power operations, and some comparisons of streamflows in different parts of the State. Most of the information shown on the streamflow maps was taken from "The Availability and use of Water in Georgia" by M. T. Thomson, S. M. Herrick, Eugene Brown, and others pub lished as Bulletin No. 65 in December 1956 by the Georgia Department of Mines, Mining and Geo logy. The average flows reported in that publication and sho\vn on these maps were for the years 1937-1955. That publication should be consulted for detailed information. More recent streamflow information may be obtained from the Atlanta District Office of the Surface Water Branch, Water Resources Division, U. S. Geological Survey, 805 Peachtree Street, N.E., Room 609, Atlanta 8, Georgia. In order to show the streamflows and other features clearly, the river locations are distorted slightly, their lengths are not to scale, and some features are shown by block-like patterns. -
Trophic State and Metabolism in a Southeastern Piedmont Reservoir
TROPHIC STATE AND METABOLISM IN A SOUTHEASTERN PIEDMONT RESERVOIR by Mary Callie Mayhew (Under the direction of Todd C. Rasmussen) Abstract Lake Sidney Lanier is a valuable water resource in the rapidly developing region north of Atlanta, Georgia, USA. The reservoir has been managed by the U.S Army Corps of Engineers for multiple purposes since its completion in 1958. Since approximately 1990, Lake Lanier has been central to series of lawsuits in the “Eastern Water Wars” between Georgia, Alabama and Florida due to its importance as a water-storage facility within the Apalachicola-Chattahoochee-Flint River Basin. Of specific importance is the need to protect lake water quality to satisfy regional water supply demands, as well as for recreational and environmental purposes. Recently, chlorophyll a levels have exceeded state water-quality standards. These excee- dences have prompted the Georgia Environmental Protection Division to develop Total Max- imum Daily Loads for phosphorus in Lake Lanier. While eutrophication in Southeastern Piedmont impoundments is a regional problem, nutrient cycling in these lakes does not appear to behave in a manner consistent with lakes in higher latitudes, and, hence, may not respond to nutrient-abatement strategies developed elsewhere. Although phosphorus loading to Southeastern Piedmont waterbodies is high, soluble reac- tive phosphorus concentrations are generally low and phosphorus exports from the reservoir are only a small fraction of input loads. The prevailing hypothesis is that ferric oxides in the iron-rich, clay soils of the Southeastern Piedmont effectively sequester phosphorus, which then settle into the lake benthos. Yet, seasonal algal blooms suggest the presence of internal cycling driven by uncertain mechanisms.
