Little Mahantango Creek

Little Mahantango Creek begins near Line Mountain, in Eldred Township, Schuylkill County. It flows south-southeast for a short distance before turning west-southwest, receiving an unnamed tributary from the right. After several tenths of a mile, the creek turns south for a few tenths of a mile, receiving an unnamed tributary from the right and two unnamed tributaries from the left. It then flows in a generally west-southwesterly direction for a few miles, occasionally flowing west-northwest for short distances, and receiving one unnamed tributary from the right and two from the left before turning northwest. Several tenths of a mile further downstream, the creek turns west-northwest, receiving two more unnamed tributaries from the right (in the process crossing Pennsylvania Route 125) and entering Upper Mahanoy Township, Northumberland County. ==Hydrology==

Reaches of Little Mahantango Creek are designated as an impaired waterbody. The cause of the impairment is sedimentation/siltation and the probable source is agriculture. The entirety of the creek and all of its unnamed tributaries and sub-tributaries are designated as impaired. In July 1998, the water temperature of Little Mahantango Creek near Pitman was once measured to be , while at Line Mountain, it was measured to be . The instantaneous discharge of the creek was near Pitman and at Line Mountain. The specific conductance was 199 micro-siemens per centimeter at near Pitman and 188 micro-siemens per centimeter at at Line Mountain. The concentration of nitrogen in nitrate in the creek was near Pitman and at Line Mountain. ==Geography and geology==

The elevation near the mouth of Little Mahantango Creek is above sea level. The elevation near the creek's source is above sea level. The geology surrounding most of the length of Little Mahantango Creek consists of the Irish Valley Member and the Trimmers Rock Formation. However, the Sherman Creek Member is present near parts of the creek's middle and upper reaches, as well as at the mouth. The geology at the headwaters of the creek consists of rock of the Duncannon Member. The main soil occurring in the vicinity of Little Mahantango Creek is the Leck Kill-Minersville-Calvin soil. However, the Berks-Weikert-Beddington soil occurs near the middle reaches of the creek and the Hazelton-Dekalb-Buchnnan soil occurs near its headwaters. ==Watershed==
