Each year The District is audited by the Office of the State Auditor. A “clean” audit is one in which no findings are issued and no material misstatements are noted in the District’s financial statements. The audit, performed annually by the Auditor’s Office, examines the District’s financial statements and its compliance with legal regulations that govern the operation of the water and sewer utility. The District takes pride in meeting its financial reporting and legal compliance obligations and the current report continues the District’s long record of having no audit findings.
The most recent three years of financial and compliance audit reports can be found at the links below. Audit reports for earlier years can be downloaded from the Washington State Auditor’s website at www.sao.wa.gov
