This layer was created by the Research & Analytics Division of the Atlanta Regional Commission to represent the rivers and streams in the state of Georgia. It contains linear hydrographic features, including rivers, streams, and artificial flow paths through water bodies. Data were captured from USGS 7.5 minute mylar separates containing the "blue-layer" from the U.S. Geological Survey's 1:24000-scale quadrangle maps. Individual quadrangles were combined and edgematched using Arc/Info GIS software, and then clipped into individual county tiles using boundary data from the Georgia Department of Transportation's 1:31360-scale County General Highway Maps.Attributes:FEATURE: Artificial Path Canal/Ditch Connector Stream/RiverFEATURE_TY: Aqueduct Area of Complex Channels Canal/Ditch Estuarine Intermittent Lake/Pond Perennial Reservoir Stream/River Swamp/Marsh UnspecifiedSTATE_FIPS = State of Georgia FIPS codeCOUNTY_FIP = County FIPS codeHUC = Hydrologic Unit CodeNAME = Name of the river or streamCLASS: Major MinorSource: USGS, Georgia DOT, Atlanta Regional CommissionDate: 1997For additional information, please visit the Atlanta Regional Commission at www.atlantaregional.com

Many central questions in river ecology and management rely on understanding the distributions of aquatic plants and their habitats. However, it remains difficult to map submerged aquatic vegetation and relevant habitat characteristics in rivers at scales beyond the scope of field surveys. We focus here on rocky shoals, which are the principal habitat of the riverine macrophyte Podostemum ceratophyllum Michx. This species is considered an indicator of the overall ecological health of the rivers it inhabits, including the well-being of several fish and invertebrate species of conservation concern. Here, we provide a map of known and likely rocky shoal habitats in three rivers in Georgia, USA, produced by a manual survey in Google Earth Pro using simple, repeatable criteria. We intend for this map to aid ongoing and future efforts to locate rocky shoals in these rivers, model the distribution and growth of associated species, and identify prospective shoals in other systems. Methods To establish an initial map of habitats potentially suitable for Podostemum, we used Google Earth Pro to search for rocky shoals along the lengths of the Middle Oconee, Conasauga, and Etowah Rivers in northern Georgia. For this purpose, we defined shoals as river reaches ≥10 m long in which rocky substrate (submerged or emergent bedrock, boulder, or cobble) was visible and turbulence was evident on the water surface at multiple time points, indicating consistently rapid water flow. Shoals separated from each other by ≥10 m were considered distinct; shoals separated by <10 m were combined. Shoal-like habitats apparently associated with historical indigenous fishing weirs (Cook, 2013) were counted as shoals. Non-shoal reaches were marked by sandy substrates and a consistent lack of turbulence on the water surface. We used several sets of field observations to support this search, including GPS records of shoals sampled in previous and ongoing experiments (Argentina et al., 2010a; Argentina et al., 2010b; Baker 2012; Freeman et al., 2017; Marcinek 2002 unpublished) and river guides for recreational paddlers (Cook, 2013; Cook, 2019). We also included river start and end points and flowlines (USGS NHD, 2023). This technique is sensitive to limitations in available imagery and our interpretations thereof. We strove to identify every location that was likely to be a rocky shoal, but factors such as narrow channel width, high tree cover, and high water level may have masked some shoals from detection. Similarly, classification of a shoal by the above criteria does not guarantee that a given habitat is actually a shoal, nor that it contains Podostemum.

Digital flood-inundation maps for a 12.6-mile reach of the Withlacoochee River from Skipper Bridge Road to St. Augustine Road, Lowndes County, Georgia, were created by the U.S. Geologicay Survey (USGS) in cooperation with the city of Valdosta and Lowndes County, Georgia. The inundation maps, which can be accessed through the USGS Flood Inundation Mapping Science Web site at http://water.usgs.gov/osw/flood_inundation/, depict estimates of the areal extent and depth of flooding corresponding to selected water levels (stages) at the USGS streamgage Withlacoochee River at Skipper Bridge Road, near Bemiss, Georgia (023177483). Real-time stage information from this streamgage can be obtained at the National Water Information System Web Interface (NWISWeb; https://waterdata.usgs.gov/ga/nwis/rt) and can be used with these maps to estimate near real-time areas of inundation. In addition, the information has been provided to the National Weather Service (NWS) for incorporation into their Ad ...

The digital flood-inundation maps included in this data release were developed for a 16.4-mile reach of the Yellow River from 0.5-mile upstream of River Drive to Centerville Highway (Georgia State Route 124), Gwinnett County, Georgia (Ga.) to depict estimates of the areal extent and depth of flooding corresponding to selected water levels (stages) at two U.S. Geological Survey (USGS) streamgages in the mapped area. The maps for the 9.0-mile reach from 0.5-mile upstream of River Drive to Stone Mountain Highway (US Route 78) are referenced to the Yellow River, near Snellville, Georgia (Ga.; station 02206500), and the maps for the 7.4-mile reach from Stone Mountain Highway to Centerville Highway are referenced to the streamgage Yellow River at Ga. 124, near Lithonia, Ga.

This record represents near real time River Ecology Monitoring Results. National surveys of Irish rivers have taken place on a continuous basis since 1971, when 2,900 km of river channel was surveyed. The National Rivers Monitoring Programme was replaced by the Water Framework Monitoring Programme from 22 December 2006. As part of the Water Framework Directive (WFD) Monitoring Programme approximately one third of our major rivers and their more important tributaries are surveyed and assessed each year by EPA ecologists. A complete survey cycle is completed every three years. The sites are scored on a five point system developed by the EPA called the Biological Q rating system.For more information on this dataset please go to https://gis.epa.ie/geonetwork/srv/eng/catalog.search#/metadata/a0179512-dca7-450d-8391-374c4bf00375

Groundwater Recharge and Pollution Susceptibility Areas: The Georgia Planning Act requires that land-use ordinances be made in an attempt to protect ground water, be passed and enforced by local governments having jurisdiction over significant groundwater recharge areas. Within significant recharge areas, the relative degree of protection required is further defined on the basis of whether the area has high pollution susceptibility.

Southern Ecological Framework: The Southeastern Ecological Framework is landscape ecology based model that identifies primary ecological areas that are protected by some type of conservation or ecosystem management program; identifies a green infrastructure network that connects these primary ecological areas. Priority Ecological Areas provide excellent candidates for Regionally Important Resources and SEF corridors provide excellent connecting green infrastructure linkages between them. DCA has converted these from the original grid model to vectors and clipped them to the Georgia state boundary for easy use in regional planning applications. Complete documentation of SEF, with Georgia application examples, is available in the EPA Final Report (5-20-2010)

Protected River Protected River River Corridor Protection Plans are required for designated streams by the Georgia Department of Natural Resources Rules for Environmental Planning Criteria 391-3-16-.04 and are also a DCA-required natural resources planning element.

The DNR map (compiled by the USGS) errantly contains river reservoir areas and does not include all of the stream segments downstream to the jurisdiction of the Coastal Marshland Protection Act area.
