Warrior Creek begins on the northern base of Wilkes-Barre Mountainon the border between Warrior Run and Sugar Notch. It flows west for a short distance along the border before turning north for a few tenths of a mile, still following the border. It then turns west for a short distance and enters Warrior Run. At this point, the creek turns north-northwest for more than a mile, entering Hanover Township and crossing Pennsylvania Route 29/South Cross Valley Expressway. It then turns north-northwest and receives an unnamed tributary from the. At this point, the creek turns west-northwest for more than a mile. It crosses the Sans Souci Parkway and reaches its confluence with the Susquehanna River. Warrior Creek joins the Susquehanna River upriver of its mouth.
Hydrology
Warrior Creek is considered to be an impaired stream. The causes of impairment are flow alterations and siltation/sedimentation. The likely source of the impairment is abandoned mine drainage. Warrior Creek lacks any major base flow until downstream of Middle Road. However, the largest abandoned mine drainage discharge in the creek's watershed has a discharge of up to 75 gallons per minute. The water of the creek downstream of Middle Road is alkaline as of 1975. This is due to raw sewage discharges. During several measurements in 1973 and 1974, the discharge of Warrior Creek ranged from 0 to 70 gallons per minute at the outlet of a culvert Middle Road. At the inlet of the culvert, the discharge ranged from 0 to 60 gallons per minute. At two pipes carrying the creek under a strip mining road, the creek was dry at most measurements. During several measurements in 1973 and 1974, the water temperature of Warrior Creek ranged from at the outlet of a culvert on Middle Road. At the inlet of the culvert, the water temperature ranged from. At the outlet of the culvert on Middle Road, the creek's pH ranged from 4.50 to 7.40. At the inlet of the culvert, the pH ranged from 6.55 to 8.45.
Geography and geology
The elevation near the mouth of Warrior Creek is above sea level. The elevation of the creek's source is between above sea level. The headwaters of Warrior Creek are in strip mines. Most of the watershed overlies coal measures. A mountain known as Wilkes-Barre Mountain is also in the upper reaches of the watershed. The surficial geology in the vicinity of Warrior Creek mainly consists of strip mining land, urban land, a glacial or resedimented till known as Wisconsinan Till, and bedrock consisting ofsandstone, shale, coal, and conglomerate. The bedrock mainly occurs near the creek's middle and upper reaches. There are also a few patches of alluvium and fill.
The drainage basin of Warrior Creek is designated as a Coldwater Fishery and a Migratory Fishery. However, a 1978 report noted that the creek was devoid of fish life.
