The Alcovy River (pronunciation: al-CO-vee) is a 69adj=midNaNadj=mid[1] tributary of the Ocmulgee River in north-central Georgia in the United States. It is part of the watershed of the Altamaha River, which flows to the Atlantic Ocean.
The Alcovy River rises in eastern Gwinnett County, 5miles northeast of Lawrenceville, and flows generally south through Walton, Newton and Jasper counties. It defines portions of the boundary between Newton and Jasper counties. It joins the Yellow River and South River to form the Ocmulgee River at Lake Jackson, a reservoir formed by a dam on the Ocmulgee. North of I-20, the Alcovy River becomes a lowland swamp for about 4miles before resuming the nature of a Piedmont stream. The lowland area contains an ecological rarity: the tupelo gum tree.
Largemouth bass, crappie, red breast, bluegill, and channel catfish inhabit the Alcovy.
