Also known as Edgbaston Park,[1] the site is based on glacial sands and gravels overlying sandstone from the Late Triassic period.

On the south side of the main pool, completed in 1790 and whose capacity is 59,100 m3 (77,300 cu yd), is an earthfill dam holding the water in and a small weir.

[2] The site is adjacent to Winterbourne Botanic Garden and Edgbaston Golf Course and close to the University of Birmingham.

Access can be gained when visiting Winterbourne Botanic Garden - admission charges apply.

The pool's bird life has been recorded since at least the 1860s[1] and has included hooded crow, nightingale, nightjar and hawfinch.
