Five regions having distinct flood-depth frequency characteristics are delineated. The developed relations, expressed as equations and graphs, are consid­ ered usable for any site in Georgia where the drainage area is between 1 and 1,000 square miles, and the. flow is natural; exceptions include streams that are urbanized, regulated, tide affected, channelized, or where manmade,struc­ tures significantly affect peak stages. INTRODUCTION When the U.S. Geological Survey began preparing maps of flood-prone areas, a need arose for a quick and easy method of determining flood depths for use in delineating approximate flood-prone areas. Regional flood-depth frequency relationships were developed for this purpose. The purpose of this report is to describe a technique for determining and using these relations for estima­ ting flood depths on most natural streams in Georgia. The flood-depth frequency relations developed herein will be of great value-in preparing flood-prone area maps in Georgia for floods having recur­ SJ rence intervals of '10, 50, and 100 years, and in answering local requests I~ concerning the depth of flooding. J DETERMINATION OF FLOOD-DEPTH FREQUENCY RELATION I, Streamflow and stage records for 217 gaging stations on areal streams I, draining basins frpm 1 to 1,000 square miles were analyzed to provide plan­ I I ners and designers with relations for estimating the depth of floods having , tt~ recurrence intervals of 10, 50, and 100 years on streams with natural "flow in I Georgia. (See figs. la-ld.) The results are valid for natural flow only, J and do not apply to streams that are urbani~ed, regulated, tide affected, channelized, or where other manmade structures significantly affect peak stage or discharge. -1- '] &l h 4 $) Q £4 J6 . ; 8S0 ·1~ 02384000 .-'..... , "~ ··., , .

The elevation of zero flow corresponds to the lowest point in the low-water '1 'TIl control, usually a riffle, just downstream from the gage or point of interest. ,c~ The'depths for selected flood frequencies were determined as follows: 1. Discharges were obtained for the 10-, 50-, and 100-year floods at 1: gaging stations using discharge-frequency data from the statewide flood-frequency study now in progress. Guidelines in Water Resources ' ~ " Council Bulletin 17 (1976) for determining flood-flow frequency are 1 being used in this study. ~ 2. The elevation of the 10-, 50-, and 100-year floods and "zero" flow were obtained from the defined elevation-discharge relations at I: gaging stations. ',:.. 3. The flood depth was computed as the difference between the elevation \ of the desired flood (10-, 50-, or 100-year flood) and the elevation ""'" of zero flow. fT- I Several gaging stations were deleted from the analysis because the I""", elevation-discharge relations for the higher frequency floods could not be defined adequately. 1'rw I i if~ Regression Analysis Since flood-depth information is collected at only a few of the many sites where this information is needed, gaging-station information must be transferred to ungaged sites. Regional analysis is a method for doing this. The regression method described by Riggs (1973) is a useful means of region­ alization as the flood depth for a given flood-frequency level can be related to physical and climatological basin characteristics. Th~~egression model used is of the form [ 'Dn = a Ab B c Cd where Dn = flood depth above bottom of channel having a n-year recurrence interval. A, B, C = physical and climatological characteristics of drainage basin. a, b, c, d = constants and coefficients

INTRODUCTION Total Maximum Daily Load (TMDL) Implementation Plans are platforms for evaluating and tracking water quality protection and restoration. These plans have been designed to accommodate continual updates and revisions as new conditions and information warrant. In addition, field verification of watershed characteristics and listing data has been built into the preparation of the plans. The overall goal of the plans is to define a set of actions that will help achieve water quality standards in the state of Georgia. This implementation plan addresses the general characterist ics of the watershed, the sources of pollution, stakeholder s and public involvement, and education/o utreach activities. In addition, the plan describes regulatory and voluntary practices/control actions (management measures) to reduce pollutants, milestone schedules to show the development of the managemen t measures (measurable milestones), and a monitoring plan to determine the efficiency of the management measures.

    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.

    CHAPTER 3 establish water use classifications and water quality standards for the waters of the State.

All of Georgia’s Background waters are currently classified as fishing, recreation, drinking water, wild river, scenic Water Resources Atlas The river miles and river, or coastal fishing. Table 3-2 provides a lake acreage estimates are based on the U.S. summary of water use classifications and Geological Survey (USGS) 1:100,000 Digital criteria for each use. Georgia’s rules and Line Graph (DLG), which provides a national regulations protect all waters for the use of database of hydrologic traces. The DLG in primary contact recreation by having a fecal coordination with the USEPA River Reach File coliform bacteria standard of a geometric provides a consistent computerized mean of 200 per 100 ml for all waters with the methodology for summing river miles and lake use designations of fishing or drinking water to acreage. The 1:100,000 scale map series is apply during the months of May - October (the the most detailed scale available nationally in recreational season). digital form and includes 75 to 90 percent of the hydrologic features on the USGS 1:24,000 TABLE 3-1.
