今年7月至10月，黄河上游来水较常年偏少21%，中游来水较常年偏多35%。来水分布不均不利于全河 用水安全保障，黄河水利委员会在确保防汛安全的前提下，全力开展汛末水库群蓄水。截至目前，黄河 中下游干支流6座水库群汛末总蓄水量105.52亿立方米，为历史同期第二高。 经济观察网 据央视新闻客户端消息，今天（31日），黄河干流骨干水库小浪底水库水位蓄至270.2米， 为历史同期最高，为今冬明春抗旱保供水打下坚实基础。 ...

Core Viewpoint - The continuous heavy rainfall in Sichuan province has led to increased pressure on flood prevention efforts, particularly for aging and potentially hazardous reservoirs, while also presenting an opportunity for water storage as the flood season approaches its end [1][2][3]. Group 1: Flood Prevention Challenges - Sichuan has issued yellow rainstorm warnings for three consecutive days, with September experiencing multiple rounds of heavy rainfall, which is unusual for this time of year [1]. - The provincial flood control command has activated four level-four flood emergency responses since late August, compared to only one response during the same period last year [2]. - The region's reservoirs, many of which are old and in poor condition, face significant challenges due to the prolonged heavy rainfall, which can lead to structural instability [2]. Group 2: Reservoir Conditions and Management - Sichuan has over 8,000 reservoirs, with more than 170 large and medium-sized ones, playing crucial roles in flood control, irrigation, water supply, and power generation [2]. - Over 80% of the reservoirs were built between the 1950s and 1970s, with a high proportion being small and earth-rock dams, which are often below standard and pose risks [2]. - The current rainfall provides a valuable opportunity for water storage, which is critical for addressing water shortages in the winter and spring [5]. Group 3: Future Water Storage Plans - The provincial water resources department is preparing for water storage efforts as the flood season concludes, emphasizing the need to increase reservoir water levels while ensuring flood safety [5]. - Recent rainfall has already led to increased water levels in several major reservoirs, indicating a positive trend for upcoming water storage initiatives [5].

通过多措并举实施精准精细灵活水量调度，广东省前汛期水量调度工作取得显著成效。 主要调度水库蓄水超额完成目标。截至7月1日，主要调度水库总可调水量73.8亿立方米，前汛期回蓄水 量21.7亿立方米，充分发挥主要调度水库蓄水作用。其中，北江流域主要调度水库可调水量较预测值偏 多1.5亿立方米，南水水库可调水量3.7亿立方米，较预测值偏多23%。鉴江流域高州水库可调水量6.1亿 立方米，较常年同期偏多5853万立方米，较预测值偏多1511万立方米。东江流域新丰江水库在来水较计 划预测值偏少24%的情况下，可调水量较预测值仅偏少3.3%。 供水及生态安全得到全面保障。龙川、博罗、高要、石角、潮安、横山、化州7个国考断面生态流量及 最小下泄流量全部达标，满足生态用水需求，有力保障了广东及香港、澳门生活和生产用水。 7月17日，据广东省水利厅消息，2025年前汛期（4月—6月，下同），在全省降雨量偏少，东江、西 江、北江、韩江、鉴江五大流域降雨分布不均的情况下，广东水利系统通过精细调度，主要水库蓄水成 效明显，较流域水量调度计划预测值（以下简称"预测值"）基本持平，完成既定蓄水目标，可调水量约 74亿立方米，占兴利库容的 ...
