Please sign and return this Proxy Card immediately (and no later than May 30, 2025) to be given effect. The undersigned, as a shareholder of BLUE LAKE SPRINGS MUTUAL WATER COMPANY, a California Corporation (BLSMWC), HEREBY APPOINTS the Board of Directors of BLSMWC, or

as proxy holder with full power of substitution, to represent the undersigned at the annual meeting of the Shareholders to be held on June 5, 2025 at 2pm at BLSMWC’s office, 1011 Blagen Road, and online via Zoom, and to vote the share of stock that the undersigned would be entitled to vote if personally present on the matter and in accordance with instructions set forth on the Statement Regarding Proxies on the following page. Each Shareholder is entitled to one vote for each share owned. Voting shall not be cumulative. The nominees receiving the highest number of votes by ballot shall be elected to fill the vacancies in office for the ensuing three-year term. Please take notice that on May 8, 2025, the BLSMWC Board of Directors shall consider the adoption of a Resolution that will reduce the total number of the Board of Directors to five Directors. This Resolution stems from the lack of Shareholder interest in submitting their names and qualifications to become a candidate for Director. If the Board adopts the Resolution, there will be one Director seat available in this election cycle. If the Board does not adopt the Resolution, there will be three Director seats available. For more information on the Resolution, please contact the Office at (209) 795-7025.
