There are 42 named tributaries of Larrys Creek, which is a 22.9 mile (36.9 km) long stream in Lycoming County in the U.S. state of Pennsylvania. Larrys Creek is a tributary of the West Branch Susquehanna River and part of the Chesapeake Bay drainage basin; its watershed drains in six townships and a borough. Despite being clear-cut in the 19th century, Note: ISBN refers to the Heritage Books July 1996 reprint. URL is to a scan of the 1892 version with some OCR typos. as of 2008 the Larrys Creek watershed is 83.1% forest and 15.7% agricultural.

The named tributaries within the watershed are presented here in three lists. Larrys Creek itself has 18 named tributaries, which are the subject of the first list. The First Fork and Second Fork of Larrys Creek are the two main tributaries of Larrys Creek, and they have multiple tributaries of their own. The second list gives the First Fork's eight named tributaries, and the third list gives the Second Fork's nine named tributaries. Finally there are seven named streams in the watershed which are tributaries of tributaries of the three main branches, and they are presented after each list. There is one such stream for Larrys Creek itself, two for the First Fork, and four for the Second Fork.The names of the tributaries, whether they enter their parent on the right or left bank, the elevations of their sources, the lengths of the First and Second Forks, and the names of mountains are all taken from the United States Geological Survey 1:24,000 scale topographic maps covering the Larrys Creek watershed, specifically the following five quadrants (all in Pennsylvania): English Center, Linden, Salladasburg, Waterville, White Pine. There are also tributaries without names, which are not included in these lists.

Each list follows the same format. The first column gives the name—27 of the tributaries are named streams, while the remaining 15 are unnamed streams in named valleys: i.e. 13 hollows, one cove, and one swale. Tributaries which are themselves unnamed, but which are in a named valley are given the name of the feature in quotation marks, for example: "Pond Hollow". The first column also notes whether the tributary enters its parent stream on the right bank or left bank. The second column in each list gives the river miles, which is the distance from the mouth of the tributary to the mouth of its parent stream (Larrys Creek or the First or Second Fork). The third column gives the area of the drainage basin or watershed for that stream. The next four columns give the latitude and longitude and the elevation of the mouth and source of each tributary, and the final column has remarks, mostly about location.

Tributaries Larrys Creek flows south from the dissected Allegheny Plateau to the Ridge-and-valley Appalachians. It rises in Cogan House Township and flows south to Green Mountain. There it turns southwest and flows under the Cogan House Covered Bridge, which is on the National Register of Historic Places and one of only three remaining covered bridges in Lycoming County. Note: This includes At Buckhorn Mountain it turns south through Pennsylvania State Game Lands (SGL) No. 114 and flows through Mifflin and Anthony Townships, passing between Coal Mountain and Harris Point. From Mifflin Township it enters the borough of Salladasburg, where it receives the Second Fork, and just south of the borough the First Fork joins the creek. These two largest tributaries drain parts of Pine, Cogan House, Cummings, and Mifflin Townships (there are named streams in the Larrys Creek watershed in all but Pine Township). Piatt Township is the last municipality the creek flows through and it enters the West Branch Susquehanna River there.

The five largest direct tributaries in the Larrys Creek watershed are the First and Second Forks of Larrys Creek, Roaring Run, Wendell Run and Wolf Run. The Second Fork of Larrys Creek is the largest tributary, with a watershed of or 28.0% of the total watershed. The First Fork is next largest, with a watershed of or 19.8% of the total. Roaring Run accounts for 5.7% of the total watershed (5.1 square miles or 13.2 km2) and other tributaries are less than 5% of the total area.

First Fork tributaries The First Fork is the second largest tributary and has its source in Cummings Township. It flows south-southeast passing to the southwest of Little Round Top and Puterbaugh Mountain, then leaves the dissected Allegheny Plateau at Fishery Point. It then enters Mifflin Township, where it joins Larrys Creek just south of Salladasburg, 4.2 miles (6.8 km) from the mouth. Historically, much of the First Fork was protected as part of the Ogontz Lodge, a private hunting and fishing club.

The four largest tributaries of the First Fork are: Tarkiln Run with a watershed of or 15.4% of the First Fork watershed; Mud Run with 2.22 square miles (5.75 km2 or 12.6%); Dog Run with 1.82 square miles (4.71 km2 or 10.3%); and Marsh Run with 0.96 square miles (2.49 km2 or 5.5%). All other tributaries are less than 5% of the total area. + Named tributaries of the First Fork of Larrys CreekName, bankRiver miles (km)Watershedarea in square miles (km2)Mouth coordinatesMouth elevation in feet (m) Source coordinatesSource elevation in feet (m) Remarks Mouth  mi (0 km)  mi2 (45.58 km2)  ft (188 m) -- -- The First Fork enters Larrys Creek just south of Salladasburg in Piatt Township.
