水利部于8月1日13时针对黑龙江省启动洪水防御Ⅳ级应急响应[1]。根据气象预报，东北地区将面临明显降雨过程，其中8月1日东北东部将出现大到暴雨，2日东北东南部将有小到中雨，3至7日东北中部北部仍将持续中到大雨[1]。
受降雨影响，黑龙江省内多条河流面临洪水威胁[1]。松花江、嫩江支流甘河可能发生编号洪水，松花江干流佳木斯江段及支流汤旺河可能发生超警洪水[1]。水利部要求地方加强水情监测预警、水工程调度，做好水库安全度汛和中小河流洪水防御工作，确保人民生命财产安全[1]。目前，水利部已派出3个工作组赴黑龙江省洪水防御一线协助指导[1]。
The Ministry of Water Resources initiated a Level IV emergency flood response for Heilongjiang Province at 1 p.m. on August 1st [1]. The measure was prompted by forecasts indicating that northeastern China will experience heavy to torrential rainfall, with potential risks of coded floods or water levels exceeding warning thresholds in major rivers across the province [1].
Specifically, the Songhua River and Nenjiang River in Heilongjiang, along with the tributary Ganhe River, face the possibility of coded floods, while the Songhua River mainstream in the Jiamusi section and its tributary Tangwang River may experience water levels exceeding warning levels [1]. The weather forecast predicts heavy to torrential rain in the northeastern eastern region on August 1st, followed by light to moderate rain in the northeastern southeastern region on August 2nd, with medium to heavy rainfall continuing across the central and northern parts of northeastern China from August 3rd to 7th [1].
In response, the Ministry of Water Resources has directed local authorities to strengthen monitoring and early warning systems, optimize the operation of water control projects, ensure the safe passage of reservoirs through the flood season, and implement flood prevention measures for small and medium-sized rivers [1]. Three working groups from the ministry are currently stationed on the front lines of flood prevention operations in Heilongjiang Province to provide guidance and assistance [1].
