White Salmon officials are looking into the possibility that building a new community swimming pool might not cost as much as has been estimated.  Mayor David Poucher and City Councilors learned about an Ellensburg firm that constructed a single lap pool in Tonasket for about $760,000, with the total project coming out to $1.25 million.  After receiving earlier estimates above $3 million, Poucher says they want to learn more about what Tonasket did, and thinks White Salmon can get its costs down to $1.25 million to $1.5 million.  Poucher says some City officials will go to look at the Tonasket pool and visit with the contractor that built it to investigate the possibility further.
