West Umatilla Mosquito Control District was created in 1971 under provisions of Chapter 452, Oregon Revised Statutes to provide a program for relief from mosquitoes in a 515 square mile area of western Umatilla County.
The district Board of Trustees have established policy and guidelines and employed personnel to implement a comprehensive mosquito control program. The program is reviewed annually for revisions to adjust to regulatory and ecological requirements or changing conditions.
The district program is financed by a property tax levy. A tax base for the district was established in the fall of 1972 and increased in May of 1996. Five year local option levies were passed in 2004, 2008, and 2012 to generate additional revenue for operational expenses.
Much of the progress in the district program is due to the support, cooperation and assistance received from numerous individuals, firms and agencies and is greatly appreciated by the board of trustees and district employees.
