Just as Portland barrels into summer heat, Portland Parks & Recreation has closed Pier Pool in North Portland due to a significant failure in a water line. The parks bureau said that water levels began rapidly dropping in the pool on Thursday and efforts to refill the pool were ineffective. Further inspection indicated the issue was a broken pipe in the circulation system. Little wonder: The PP&R statement adds that “a large portion of Pier Pool’s inner mechanical workings are original parts dating from as far back as 1940.”
