Pleasant Run is approximately 7 miles (11 km) in length,[1] running from its headwaters near Cushetunk Mountain,[2] a plutonic intrusion of igneous rock surrounding Round Valley Reservoir, through Readington and Branchburg, to its convergence with the South Branch Raritan River near River Road in Branchburg.
Pleasant Run was originally called Campbell's Brook after John Campbell of Piscataway. Campbell in 1685, was granted a strip of land extending west from the South Branch and which surrounded Pleasant Run.[3]
Pleasant Run has twenty-three small, unnamed tributaries in Branchburg and Readington.
