'''Lake Run''' is a [[tributary]] of [[Roaring Brook (Lackawanna River)|Roaring Brook]] in [[Lackawanna County, Pennsylvania]], in the United States.

It has one named tributary, which is known as Emerson Run. Lake Run is considered to be [[Class A Wild Trout Waters]]. The surficial geology in its vicinity consists of Wisconsinan Ice-Contact Stratified Drift, Wisconsinan Till, Boulder Colluvium, alluvium, bedrock, sand and gravel pits, fill, wetlands, peat bogs, and a lake.
==Course==
Lake Run begins in [[Henry Lake (Pennsylvania)|Henry Lake]], in the community of [[Eagle Lake, Pennsylvania|Eagle Lake]], in Covington Township.<ref name = "nationalmap"/> The stream flows west-northwest for several tenths of a mile before turning north-northwest for more than a mile, flowing in a valley on the border of Eagle Lake and receiving the tributary Emerson Run from the [[wikt:left bank|left]]. The stream eventually leaves behind the border of Eagle Lake and turns northwest for several hundred feet before reaching its confluence with Roaring Brook.<ref name = "nationalmap"/>
Lake Run joins Roaring Brook {{convert|17.50|mi|km}} upstream of its mouth.<ref name = "gaz">{{Citation|url = http://www.lycoming.edu/cwi/pdfs/paGazetterOfStreams.pdf|title = Pennsylvania Gazetteer of Streams|date = November 2, 2001|accessdate = April 15, 2015}}</ref>
===Tributaries===
Lake Run has one named tributary, which is known as Emerson Run.<ref name = "nationalmap"/> Emerson Run joins Lake Run {{convert|0.84|mi|km}} upstream of its mouth. Its watershed has an area of {{convert|1.58|sqmi|km2}}.<ref name = "gaz"/>
