1Broad River Watershed Assessment Rachel HodgeClaire IkeRobin Barker
2Problem Statement:No comprehensive studies have been conducted regarding the ecological, hydrological, historical, economic, political, and social features within the Broad River watershed. A wide-ranging water basin characterization will allow the Broad River Watershed Alliance to identify important water monitoring sites.
3Broad River Watershed Alliance Founded in 1991Work with landowners to ensure protection of lands from harmful developmentAct to conserveEducation and outreach through public forumsAdopt-A-Stream monitoringRiver clean-ups
4Broad River Background Approximately 944,000 acres and includes parts of thirteen Georgia counties.One of the last free-flowing rivers in Georgia.Flowing south from its headwaters in Banks and Stephens Counties through Madison and Elbert Counties to its confluence with the Savannah River at the Clarks Hill/Strom Thurmond Reservoir.Provides drinking water for the cities of Royston and Franklin Springs and it is an industrial and agricultural water supply for the region.Recreational uses throughoutCanoeing, camping, kayaking, etc.Provides habitat for deer, turkeys, bobcats, foxes, beavers, otters, muskrats, quail, dove, mallards, wood ducks, turtles, crayfish and many others.
5Threats to Watershed Agricultural non-point source pollution Septic systemsLandfill leachateLitterConstruction in the floodplainRiverbank erosionDestruction of the vegetative bufferLack of tributary protectionPoorly planned development
6Heading North: What we Found on the South Fork Sandy CreekShallow, can see the bottom from the top of bridge, turtles, brown water, shoal areas, exposed rocks, birds.Watson Mill Bridge St. ParkExposed rock, bridge that separates flowing water form reservoir (dam), water is clear with minimal trash, hydroponic vegetation.Hwy 72slow water flow, shallow, sandbars, fallen trees, 80% canopy cover, stream not very wide.South Fork Hwy 72minimal water flow, cut bank on one side, fallen trees blocking flow, turbid waters, sandy brown sediment.*Study points also taken from EPA
