There is a lot of water testing going on around here these days. Seattle Parks officials tell CHS they’re working to figure out why the Cal Anderson reflection pool water has taken on a red hue. If it turned purple this week, there would be no questions. But apparently water testing is needed to figure out what, exactly, is plaguing the duck-friendly pool. “Our crews will take a sample to have the water tested this week,” a spokesperson said. “Once we have results, we will develop a plan to drain, clean and refill the pool.”
While a working reservoir still lurks below Cal Anderson (CHS wrote about it here in 2015 when the facility was due for a cleaning), the reflecting pool next to the pump house is purely for aesthetic. There has been a reservoir at the site for 115 years. After the state mandated that Seattle’s open water sources needed to be covered in the early 1990s, community groups helped lead an effort to cap the reservoir with a park. The ripple pool and water mountain have become an iconic element of the neighborhood. But a murky red pool? Not as much.
