Koroop
Koroop is a rural locality east of Kerang, reaching to Koondrook on the Murray River and to Macorna North. It is situated on an alluvium plain through which meander the Pyramid and Barr Creeks.
Farm selections were taken up in the mid-1870s and a school was opened in 1879. The Koroop post office also opened in 1879, but the origin of the place name is apparently unrecorded. Settlement concentrated around Barr Creek where the Cohuna Water Trust built several small weirs in the 1880s for irrigation.
