Notes
The excavation work by Thames Water (Aquatic Engineering) is now complete. A large lagoon has been created from what was previously a fen type environment. The intention is to add reeds grown on matting to the lagoon in the summer. The excavation works may impact on results from today and going forward. I sampled from the inlet pipe from the lagoon to the small pond in front of the exit point/tower. This avoids the duckweed which is covering most of the pond.
