Our History


In North Central Washington, the communities of Bridgeport, Brewster and Pateros decided in 1947-1948 that a hospital was needed. All three communities solicited funds and hosted fundraising projects. After the project began, financial difficulties developed and the Board of Directors realized forming a hospital district was the only answer. The District was formed and tax monies made it possible to complete the 12-bed facility, which opened January 12, 1949.

On March 2, 1951, the facility was dedicated as McKinley Memorial Hospital in honor of Dr. Charles McKinley, one of the first physicians in the area.

In 1954, a waiting room and offices were added to the hospital, and 26 patients were being treated in the 12-bed facility.

With the construction of Chief Joseph Dam in Bridgeport and an influx of new residents throughout the district, it soon became apparent the hospital was no longer adequate and could not be made so by state standards, so plans began for a new hospital.

history8The hospital district boundaries at the time included Duley Lake, Monse, Brewster, Pateros, and the lower Methow areas. However, patients were also coming from northern Douglas County and the upper Methow Valley. It was decided that the first step toward expansion was to enlarge the District. This was done by consolidating District No. 2 (upper Methow to Mazama), and annexing the Douglas County areas around Bridgeport and Mansfield. A name for the new district area was needed, so then-Administrator Howard Gamble named the district Okanogan Douglas County District Hospital.

The new 35-bed hospital opened on June 13, 1959 after a bond issue was authorized by the voters. As an additional part of that bond, the voters also agreed to a remodel of the old building into a 36-bed nursing home that was completed at a later date.

With the opening of a new private assisted living facility in Brewster in 1969, all of the nursing home residents were moved, allowing for the utilization of the old hospital for ancillary departments including physical therapy and medical records, plus a conference room and offices for purchasing and administration.

history2In 1973, again due to an extreme bed shortage and the need to enlarge and remodel some areas to meet improved building and operation standards, the voters authorized expansion of the facility to 50 beds. This construction allowed the hospital to have new surgery suites, a surgical recovery room, a completely separate coronary care unit, a pediatrics room, a bigger laboratory, and larger waiting room.

The voters authorized the construction of an eight-bed Intensive Care Unit in 1984. This addition, along with some remodeling, helped the hospital grow to a total of 48 beds.

history4In 1986 the west wing was converted from patient rooms to ancillary service areas, and in 1987 a nuclear medicine department was added. In 1988, radiology and respiratory therapy were moved and remodeled, which resulted in a 43-bed facility. From 1998 through 2010, Okanogan Douglas County District Hospital continued adding services requested by hospital district residents, including the Healthbeat Fitness Center, Advantage Durable Medical Equipment, and the Health and Wellness Center. During 2011, the business and administration offices were moved into the former Hillcrest House building at the north end of the campus to provide easier access and help allow space for needed patient care services elsewhere in the hospital.

history7Towards the end of 2011, the Board of Commissioners decided it was time to change the name of the hospital. A public contest was held within the district and from more than 100 contest entries, the name “Three Rivers Hospital” was selected. While the official name of the hospital remains Okanogan Douglas County District Hospital No. 1, we do business as Three Rivers Hospital.

In April 2020, we bid a sad farewell to our award-winning obstetrics program, as these services for Okanogan County became centralized at Mid-Valley Hospital in Omak. Three Rivers supported this decision to preserve OB services for our rural area, as there were too few providers practicing obstetrics to meet the need for all three hospitals in the county.

Today, Three Rivers Hospital offers a full spectrum family practice clinic, general surgery, women’s health services including gynecology and 3D mammograms, speedy laboratory tests, state of the art imaging, orthopedic services, transitional care for extended recovery close to home, virtual endocrinology visits, IV therapy, physical therapy, and an emergency department staffed with physicians 24/7.
