Water diversion efforts hydrate parched north
China DailyVolunteers take samples from the Danjiangkou Reservoir in Hubei province to assess water quality in August 2022. Li's responsibilities include patrolling the reservoir, collecting garbage from the water and along the shore, and promoting public awareness about water conservation. "We remove underwater fishing cages because fishing pollutes the water and harms the environment," she explained, standing on the boat where she and her fellow volunteers work daily. Known as "Well Guardians", these volunteers play a crucial role in conserving water and ensuring the reservoir's water quality. In China's five-tier surface water quality classification system, Grade II water is suitable for drinking water sources and can also serve as sanctuaries for rare fish species.
