Since Monday the Army has been struggling to make safe a World War II bomb dredged up from the Prescott Channel in the Bow Back Rivers network.

It has now been neutralized but an explosion would have been felt not only on the Lea Valley Walk at nearby Three Mills but also in Stratford and Bow.

The bomb was found in the water near the original Big Brother site where a footpath has been closed for some time whilst a new lock is built. This path features in the latest guide’s final chapter called Olympic Park Walk. Fortunately I had warned that the route would be subject to change during the building work.

The Greenway, the best view of the Olympic Park, remains open; see pages 115, 119 and 134.
