Watergate

"Watergate" is the seventh episode of the fourth season of Stargate SG-1.

Plot
After discovering that Stargate Command can't use its Stargate, it is learned that the Russians have recovered the Stargate that was onboard Thor's ship, the Biliskner, when it crashed on Earth from a Replicator attack. The Russian gate is "stuck" on an outgoing wormhole, preventing the American gate from being activated.

At the request of Dr. Svetlana Markov, SG-1 is sent to investigate why this is. When they arrive at the Russian base, they discover that everyone there is dead. After turning off the Russian Stargate, Markov, Dr. Daniel Jackson and Major Samantha Carter go through to the Water planet to figure out what was keeping it on, while Colonel Jack O'Neill and Teal'c look around the base. They manage to find Colonel Harold Maybourne in a freezer, but when they take him out, he is miraculously revived, and small, watery alien beings come out of him. The water vapor alien then enters Teal'c, and use him to go to the Stargate. O'Neill attempts to stop him, but Teal'c opens the gate, and the aliens come out of Teal'c and go through the Stargate.

Meanwhile, on the other side, it is discovered that the water that has submerged the civilization are actually aliens, the same kind that infected Maybourne. After the beings go through the Stargate to their homeworld, Markov, Daniel and Carter are sent back to Earth, having had their sub crushed and having been captured by the aliens. The Russian Stargate program is then shut down and Maybourne is arrested.
