Rh Spring creek and South creek, waters nearly the whole of Gregg township. Black creek, a smaller stream to the north, flows directly to the river and drains the slate area north of the Oriskany sandstone ridge in this township.

2d. White Deer creek, rising near the Centre county line, flows eastward between White Deer and Nittany mountains to White Deer Mills, through a valley of Clinton and Salina rocks.

3d. Buffalo creek, entering the river at Lewisburg, drains through its tributaries, Little Buffalo, Spruce run and Rapid run, a large portion of the Buffalo valley in Union county, its branches rising between spurs of the Buffalo mountains and watering the fertile plain to the west of Lewisburg.

4th. Turtle creek, a small stream draining the region between Lewisburg and the Shamokin mountain, and entering the river at Turtleville, 4 miles below Lewisburg.

5th. Penns creek, the largest stream in the district. which, after watering a large portion of Centre county, breaks through Paddy’s mountain about 3 miles west of the Union county line in a beautiful horse-shoe bend, and flows for 16 miles through Union county, along the north base of Jack’s mountain to Centerville. From here it forms the line between Union and Snyder counties for about 7 miles, where it cuts diagonally across the Devonian and Catskill areas of Snyder county, to the river at Selinsgrove. It has many branches in both counties, but they are small. In its flow of about 36 miles from the gap in Paddy’s mountain to Selinsgrove, it falls about 540′, or an average of 15′ per mile.

6th. Middle creek, rising along the Mifflin county line, drains all that portion of Snyder county between Jack’s and Shade mountains, and empties into the river only about 2 miles below Penns creek at Selinsgrove. Through much of its course in Snyder county it furnishes the avenue for the Sunbury and Lewistown railroad, breaking south at Kremer Station across the expiring end of the Shade mountain anticlinal and making a wide loop in the Devonian slates east of Freeburg before reaching the river.
