History
In 1899 Issac Polhamus and Jack Mellon owners of the CSNC had to choose one of their remaining steamboats to rebuild to keep up with the competition. The old boats were wearing out in competition with newer boats. Both the 23-year-old Mohave II and the Gila, with 35 years on the Colorado River, had worn hulls only kept going with a lot of maintenance. The Gila despite its age had better engines, and so it was chosen.
In late 1899 the Gila's machinery was refurbished and its hull rebuilt for $25,000 in the shipyard at Yuma, Arizona. Launched on November 8, 1899, it was renamed the Cochan it was two tons lighter and 14 feet shorter than the Gila. Cochan displaced 234 tons, was 135 feet long, 31 feet wide beam, and drew only 11 inches of water unloaded. It could carry 125 tons of freight, drawing less than two feet of water.

Why this record matters
A short description can identify a subject without explaining its stakes. For “Cochan (sternwheeler)”, the useful work is to connect “colorado River steamboat” to the records capable of establishing context and consequence.
Place names and jurisdictional language are key evidence: both can reveal earlier catalogue descriptions and overlooked record series. The source revision retrieved here is dated Oct 22, 2024. The linked authority identifier is Q20711086. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1900, 1909 and 1899.
A single description cannot reconcile every naming convention, rebuilding phase or administrative transfer associated with a place. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
