Historic Hood River
I ran across this when I was doing some research for the restoration of the Union Building, originally the Davidson Fruit packing house. When these well-insulated buildings where built circa 1905 they were outfitted with a state of the art refrigeration unit. Water from Wilson’s reservoir was used to spin a turbine which compressed ammonia, the common refrigerant of the era.
This advertisement indicates they manufactured two grades of ice: a high-grade ice made with city water, and a lower grade ice made with Indian Creek water from the same source which powered the compressors. I think “London Smoke” is a brilliant piece of marketing.
