Green algae cover the lake at Daecheong Lake in Daejeon, South Korea, on August 23, 2025. Green algae blooms occur when nutrients like nitrogen and phosphorus from land are washed into water bodies by rain, and water temperatures rise, creating ideal conditions for harmful cyanobacteria to thrive. Cyanobacteria, a type of phytoplankton, are essential components of aquatic ecosystems. However, when they proliferate excessively, they can produce foul odors, degrade water quality, and even cause fish deaths. This year, green algae in Daecheong Lake begin spreading in the latter part of last month.
