[2] The creek heads south for less than a mile, and crosses into Hall County to form Pony's Lake, then crosses back into Lumpkin County, picks up an unnamed branch that originates and runs parallel to Yellow Creek to this point, and heads back into Hall County approximately one mile further on.
This arm also receives one additional unnamed branch coming from the north, before Yellow Creek meets the Chestatee River, which is submerged under Lake Lanier at their point of confluence at the intersection of the two Lake Lanier arms.
[3] The creek watershed and associated waters is designated by the United States Geological Survey as sub-watershed HUC 031300010701, is named the Yellow Creek-Chestatee River sub-watershed, and drains an area of approximately 27 square miles south of Dahlonega and west of Murrayville.
The sub-watershed also encompasses the northern portion of the Chestatee River arm of Lake Lanier in Lumpkin County, which is to the west of the Yellow Creek arm, and which is where the Chestatee flows into Lake Lanier.
A small portion of the sub-watershed to the west of the Chestatee arm is located in Dawson County.
