Duwamish was a planet in the Duwamish system, located several days travel from the Romulan Neutral Zone in the galaxy's Alpha or Beta Quadrants. It was the site of a 23rd century Federation colony.
History and specifics[]
Most of the colonists lived on the world's southern continent.
In the year 2269, its population of more than seven million individuals was threatened by intense flooding. Starfleet dispatched the nearest starship, the USS Enterprise, to assist in evacuations, provide emergency quarters aboard the ship, and supply any needed medical supplies and food rations. En route, Gary Seven compelled the ship's crew to divert and aid in a crisis in the Romulan Neutral Zone for several days. But through his Aegis technology, the ship arrived at Duwamish two hours earlier than expected. (TOS novel: Assignment: Eternity)
