A Super El Niño weather pattern is predicted for Summer 2026 and is expected to bring warmer, drier conditions to Washington, severely impacting lakes through reduced stream-flows, lower water levels, and accelerated snowmelt. These conditions increase drought risks, enhance wildfire potential, and degrade freshwater habitats, harming fish and increasing algae bloom risks.

Water Quality Hazards: Warmer, stagnant water increases the probability of algae blooms and reduces oxygen levels.

Increased Water Temperatures: A warm summer combined with El Niño’s typically hot weather increases surface water temperatures, which can negatively impact aquatic life.
