The Yuima Municipal Water District (“Yuima” and/or “District”) was organized on January 19, 1963 under the Municipal Water District Act of 1911. The organization was needed for the prime purpose of importing Colorado River water to the areas populated mostly within the mutual water companies existing in the Pauma Valley area (Palomar Mutual Water Company later known as Improvement District "A"; Rancho Estates Mutual Water Company; Rancho Pauma Mutual Water Company; and Lazy H Mutual Water Company) in order to augment their local water supplies. The District takes its name from a creek tributary to the River, which means "Snow Water" in the Native American Language.
