The Alcovy River rises in eastern
Gwinnett County, 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 before resuming the nature of a
Piedmont stream. The lowland area contains an ecological rarity: the
tupelo gum tree. == Fishing ==
