Joining the Atlantic Fleet on 11 October 1905, "Colorado" trained and took part in drills along the east coast and in the Caribbean — as well as participating in ceremonies – until 7 September 1906, when she sailed for duty on the Asiatic Station. After cruising to Japan and China to represent American interests in the Far East, she returned to the west coast on 27 September 1907 for exercises along the Californian and Mexican coasts, in the Hawaiian Islands, and off Central and South America. The running aground of the USS Colorado on August 15, 1908 lead to the creation of a lighthouse in Puget Sound. On 26 August 1909 one of her Launches had a minor collision with the ferry between West Seattle, Washington and Seattle with minor damage. She served again in the Far East from September 1909 – February 1910.
