A $14 million renovation of the reflecting pool at the Lincoln Memorial in Washington D.C., commissioned under former President Donald Trump, has resulted in unexpectedly green water. The project aimed to restore a deep blue hue to the water, intended to mirror the color of the American flag. However, shortly after completion, an algal bloom turned the water a noticeable green color. Officials have not yet determined the exact cause of the bloom, but algae growth is a common occurrence in such environments. The National Park Service is currently assessing the situation and working to restore the desired water clarity. The incident has drawn criticism, given the substantial cost of the renovation and the unanticipated outcome. The pool remains open to visitors despite the discoloration.
