New natural flood management scheme helps protect homes The next phase of the Environment Agency's Lustrum Beck flood scheme is complete - and helped protect homes in Stockton-On-Tees during Storm Christoph From: One of the storage basins full with flood water during Storm Christoph. New natural flood management features have helped protect a Teesside town from flooding just weeks after they were completed. Three storage basins designed to hold back flood water upstream at Coatham Wood and reduce river levels in Stockton-on-Tees successfully filled up during heavy rain as Storm Christoph swept across the region. The temporary storage areas then slowly drained the water back into Coatham Beck, a tributary of Stockton’s Lustrum Beck, as the rain eased.
