BEIJING -- China's Ministry of Water Resources on Sunday activated a Level-IV emergency response for flood control in Beijing.

Since Thursday, the Chaobai River has experienced heavy to torrential rainfall. The Miyun Reservoir, located in the northeast suburbs of Beijing, on Sunday recorded its largest inflow flood since the reservoir was built over six decades ago, according to the ministry.

Over the next three days, the Chaobai River will continue to experience moderate to heavy rain, and some small and medium-sized rivers within the affected zones may experience floods above the warning level, it said.

The ministry urged local authorities to strengthen the monitoring and forecasting of rainfall and water levels and to promptly issue early warning information.

Measures must be taken to ensure the safety of ongoing projects and reservoirs, enhance dike inspections and defenses, and ensure that risks are detected and mitigated early, it said.

The ministry also urged efforts to prevent floods in small and medium-sized rivers and to relocate individuals from dangerous areas in advance, to safeguard the lives and property of the people.
