As of Fall, 2017, there over 330 paid members of the Spirit Lake Protective Association. Annual dues cover membership from January 1 through December 31. However, there are more than 800 shoreline properties on Big Spirit Lake, and it is the goal of the SLPA Board of Directors that every shoreline property owner on the lake be a member. Please tell your neighbors about the Spirit Lake Protective Association and encourage them to join. Dues are only $30.00 per year. Additional funds are appreciated for fireworks and for the many special projects undertaken by the association.
