Northern Wasco County Parks and Recreation District Executive Director Scott Baker says he doesn’t know when they will be able to reopen the Northern Wasco Aquatic Center.  The swimming pool in The Dalles was closed to the public as of today due to a region-wide liquid chlorine shortage that has led suppliers to ration distribution to municipal water systems and cancel deliveries to non-essential customers, including public swimming pools.  Baker explains the manufacturer in Longview encountered problems two weeks ago, and that has led to the shortage.  He adds they are sourcing other liquid chlorine suppliers.  Baker added that liquid chlorine has a shelf-life similar to milk, so the district could not buy a summer’s worth of it all at once.
