Inconsistency: spillway capacity "400,000 cu ft/s (11,000 m³/s)" — 400,000 cfs = 11,327 m³/s, not 11,000; and 2 × 5,700 m³/s ≠ 11,000 m³/s
The specifications table lists total spillway capacity as 400,000 cu ft/s (11,000 m³/s), with each individual spillway at 200,000 cu ft/s (5,700 m³/s). These figures contain two related inconsistencies.
Inconsistency 1 — total capacity conversion:
400,000 ft³/s ÷ 35.3147 = 11,327 m³/s (not 11,000 m³/s)
Conversely, 11,000 × 35.3147 = 388,463 ft³/s (not 400,000 ft³/s)
The discrepancy is ~327 m³/s (~3%). The metric value of 11,000 m³/s corresponds to only 388,000 cu ft/s.
Inconsistency 2 — individual vs. total metric values:
Each spillway: 5,700 m³/s × 2 spillways = 11,400 m³/s total
This contradicts the stated total of 11,000 m³/s (a discrepancy of 400 m³/s).
Note: the individual cu ft/s figures are internally consistent (2 × 200,000 = 400,000 ✓). It is the metric conversions that are inconsistent. The correct metric equivalent for 400,000 cu ft/s is approximately 11,300 m³/s.
