A mobile Anomaly reopened at the reservoir, and a Mosasaur and a bolus of Anthony Barton's remains came through into the reservoir, and the reservoir's waters initially began to drain out through the Anomaly. After the bolus was found, the Home Office and Special Forces went to and sealed off the reservoir, and sent divers into the waters in search of the Anomaly.
Later the warmer sea water from the Cretaceous flowed in to the reservoir via the Anomaly creating steam. This allowed Nick Cutter and Stephen Hart to find the Anomaly, and the Mosasaur fled back through after being fended off by Connor Temple, and the Anomaly then closed. (Episode 1.3)
- The reservoir is located twenty miles from the Crystal Palace Diving Institute, on the mobile underwater Anomaly's temporal fault line. The Dexter house is located directly between the Institute and the reservoir.
