Las algas son organismos diminutos parecidos a plantas que viven en el agua y usan la luz del sol para crecer. Cuando se multiplican rápidamente, pueden formar una floración de algas que pone el agua verde. Las floraciones suelen ocurrir cuando entran nutrientes extras al agua. Demasiadas algas pueden bloquear la luz del sol y consumir oxígeno, dificultando la supervivencia de peces y otra vida del lago.
