West End Brook is a small stream in southern England. It rises near the Hampshire village of Tadley. Its name is probably related to the parish, and village, it passes through for some of its course: Mortimer West End.The source is very close to West's Meadow, Aldermaston SSSI, from where the stream travels East, passing through Upper Moor's Gulley to the South off AWE Aldermaston. A tributory joins the stream here, arriving from Decoy Pond, within the AWE site.
