It's amazing to discover you have a direct link to The Thames across the road by the bus stop you use to get in to Wimbledon. The Pyl Brook rises over in Sutton but there are two tributaries that form by Grand Drive having collected rain water that gathers on Cannon Hill. The Pyl joins up with the Beverley Brook before flowing into the Thames between Barnes and Putney.
This means I am going to go 'off piste' out of the borough to Sutton and Wandsworth. Watch this space.
The Beverley Brook is one of the 16 rivers and canals (not including The Thames) which form the London Blue Ribbon Network:
