The Lincoln Memorial Reflecting Pool is many things.Murky. Peaceful. Stinky. The backdrop for protests, vigils, celebrations and stunning sunrise photos. Beset by gnats and algae. Scenery for a run. A key part of the capital's carefully designed monumental core.

Public service announcement for anyone planning to visit Washington, D.C., in the immediate term: Steer clear of President Donald Trump’s hot mess of a reflecting pool.

By June 15, the water had been taken over by algae.
