黄委加大骨干水库下泄流量，全力保障春灌用水高峰期供水安全

Core Viewpoint - The Yellow River is currently experiencing a peak in spring irrigation water demand, prompting the Yellow River Conservancy Commission to increase water discharge from key reservoirs to ensure water supply safety during this critical period [1][2] Group 1: Water Discharge Adjustments - On April 21, the discharge from the Liujiashan Reservoir was increased from 1,000 cubic meters per second to 1,100 cubic meters per second, and from the Xiaolangdi Reservoir from 800 cubic meters per second to 1,000 cubic meters per second [1] - The total water discharge from the Yellow River main stream increased from approximately 800 cubic meters per second at the beginning of April to 1,396 cubic meters per second by April 21 [2] Group 2: Water Resource Management - As of April 21, the total water storage in five major reservoirs (Longyangxia, Liujiashan, Wanjiazai, Sanmenxia, and Xiaolangdi) reached 29.374 billion cubic meters, which is 0.515 billion cubic meters more than the same period last year [2] - The Yellow River Conservancy Commission has made multiple adjustments to the discharge rates of key reservoirs since mid-February, with four adjustments for Liujiashan and seven for Xiaolangdi [2] Group 3: Drought Conditions and Irrigation Needs - The upper reaches of the Yellow River have entered a spring irrigation phase, with significant water demand as winter wheat in the middle and lower reaches is entering critical growth stages [1] - Localized areas in the Yellow River basin have been experiencing high temperatures and low rainfall since April, leading to varying degrees of drought in some irrigation districts [1]
