Foudry Brook is a small stream in southern England. It rises near the Hampshire village of Baughurst named as Beaumonts Stream or Beaumonts Brook.
From Baughurst the brook flows eastwards though Tadley and the Pamber Forest nature reserve; thereafter it turns northeastwards, skirting below and around Silchester Roman Town, and its name changes to Silchester Brook.
Once in Berkshire it adopts its final name of Foudry Brook before flowing through Mortimer and onward towards Swallowfield, here it is prevented by slightly higher ground from joining the River Loddon, so instead it turns north towards Reading.
After passing under the M4 motorway, the stream passes between the Green Park Business Park and the Madejski Stadium and football centre west of Whitley, where it provides the water for the meadow-landscaped lakes. It then passes open under a large roundabout, carries on past Thames Water's main sewage works and A33 road (to the west) and the Brunel Retail Park (to the east), before discharging into the combined River Kennet and Kennet and Avon Canal channel as their easternmost main tributary just east of the main road's Canal Bridge (Numbered 8A). At this point the Kennet adopts the Foudry's direction of north to flow into almost the centre of Reading before resuming a more its eastern direction and flowing into the River Thames downstream of Reading Bridge.
Chalk is the major aquifer in the Berkshire area. In the areas underlying Foudry Brook an overlying layer of clay and sand confines the chalk
Foudry Brook has the typical characteristic of clay catchment rivers. It has a very variable flow rates, a low base flow component and a ‘flashy’ nature; it responds quickly to extreme rainfall events due to the impermeable nature of the clay over which it flows and the resulting high surface water runoff.
