Pix Brook

Pix Brook is in length. Environment Agency data gives the Pix Brook a catchment area of . It is one of twenty water bodies making up the Ivel Operational Catchment. ==Course==

Pix Brook, approximately long and draining a catchment area of about , rises from springs at Norton Common in Letchworth Garden City and flows through Letchworth and Arlesey before joining the River Ivel at Stotfold. ==Water management==

The Letchworth Sewage Treatment Works operated by Anglian Water discharges treated waste water into Pix Brook. ==River Modification==

In Letchworth the brook is culverted through Howard Park, and the roadway of Rushby Mead bordering the eastern edge of the park follows the curves of the brook. ==Geology==

A study published in the mid-1990s described Pix Brook as a shallow stream over a bed of coarse-grained calcareous gravel and sand, noting its 'relatively steep' gradient fall of per km in comparison to the less than per km fall of the River Ivel. At Norton Common local nature reserve, mineral-rich springs supply the brook. ==School relocation==

A school named Pix Brook Academy was initially based at Etonbury Academy from 2019 but a year later moved to newly constructed facilities in Stotfold. == Incidents ==

Pix Brook flooded on 4 July 2015 with five properties in Stotfold affected. A formal investigation by Central Bedfordshire Council determined the flooding was likely caused by torrential rain over stretching the drainage system, compounded by wood and watercress debris clogging up a culvert trash screen installed earlier that year by The Bedfordshire and River Ivel Internal Drainage Board. ==References==
