Project summary

Edit project overview to modify the project summary.


Kenton Brook is a main river that drains a predominantly urban catchment in Harrow and Brent. A 1km open channel drains through Queensbury Recreation Ground joining the Wealdstone Brook and eventually the River Brent. It is a significant pathway for flood flows that contribute to flooding downstream and is recognised as a Critical Drainage Area in the Harrow Surface Water Management Plan.
