The Glaze Brook drains a large area around Leigh and is formed at the outflow of Pennington Flash 53°29′06″N 2°32′07″W close to Aspull Common. Pennington Flash is fed by Hey Brook, a continuation of Nan Holes Brook, which runs eastwards from Ashton-in-Makerfield.
After picking up the waters of Bedford Brook, which runs southward from Leigh and the Black or Moss Brook coming west from Worsley via Chat Moss, the brook turns southward, ultimately draining into the River Mersey section of the Manchester Ship Canal near Cadishead.
The Glaze Brook's catchment drains the flat lowland around Leigh which reaches a maximum altitude of 158 mAOD. The brook flows through largely agricultural land. Its tributaries extend into former mining and industrial areas in which mining subsidence has created flashes (lakes) at Pennington and Westleigh. The underlying geology is the sandstone and coal measures of the Lancashire Coalfield.
