Red Brook (Stony Brook tributary)

Red Brook is a tributary of Stony Brook in Wyoming County, Pennsylvania, in the United States. It is approximately 1.7 mi long and flows through Forkston Township. The watershed of the stream has an area of 1.86 sqmi. The stream has been named one of the best places for hiking in Wyoming County and features waterfalls, cascades, cliffs, and boulders. Its headwaters are in Coalbed Swamp, a combined boreal conifer swamp and shrub swamp.

Course
Red Brook begins on Dutch Mountain in Coalbed Swamp, in Forkston Township. It flows northeast for a short distance before turning east-southeast and entering a valley. After several tenths of a mile, the stream turns east-northeast for several tenths of a mile. It then reaches its confluence with Stony Brook.

Red Brook joins Stony Brook 1.86 mi upstream of its mouth.

Biology
Coalbed Swamp, which is in the watershed of Red Brook, is listed on the Wyoming County Natural Areas Inventory. This swamp is home to part of the largest population of yellow-bellied flycatchers in Pennsylvania. The swamp has an area of 140 acre, about half of which is a boreal conifer swamp dominated by red spruce. The rest of the area consists of a shrub swamp dominated by blueberry bushes, leatherleaf, and sedges.
