Climate Evaluation

Mutation ReasoningThe new claim focuses narrowly on the floodwater retention volume (~15 billion m³) achieved by three specific cascade complexes during joint operation, matching the 2018 source evidence verbatim. However, it omits reference to the broader historical context: five reservoirs collectively providing 28.7 billion m³ of flood-control capacity — representing 70% of the system’s total deliverable capacity. This omission shifts emphasis from systemic capacity and institutional coordination (five-reservoir framework) to a narrower, decontextualized achievement of three dams. While not contradictory (the 15 billion m³ figure is consistent and likely a subset), the selective framing drifts away from the comprehensive operational architecture previously emphasized, reducing conceptual scope without denying prior claims.
