There are four different levy measures on the ballot in Klickitat and Skamania counties in Tuesday’s election in Washington. Ballots must be postmarked by Tuesday to be counted. Three of the levies are maintenance and operations levies for schools. Voters in the White Salmon Valley, Lyle, and Trout Lake school districts are being asked to approve those. The other is in the Home Valley Water District, where a decision will be made on a maintenance and capital improvement fund levy.
