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].
