The Erundai floodgate was a floodgate protecting the Erundai Outpost in the Gimlick Valley. It was a dam, and it filtered water into canals throughout the Fongoid settlement. The Agorian commander, Argos, destroyed the floodgate, leaving the outpost to waste. However, Ratchet and Clank went back in time to save the outpost. In the version of the outpost when the floodgate was no longer up and running, the canals in the settlement were all infected and dirty. The floodgate however, provided pure water for the outpost. It was here where Ratchet fought Argos.
