What It Is
USGS gauge 01646500 --- real 15-min discharge, Potomac near DC, 2024 (public domain)
Interpretation
Standard analysis sees: right-skewed; smooth / autocorrelated; long-range memory (persistent); volatility-clustering (bursty); multifractal; nonstationary / drifting. The atlas finds no named structure, but the source is distinctively extreme on Navier-Stokes:cascade_asymmetry (+4.1z) — beyond what the standard bank predicts for it. It sits beside Pressure in the atlas (standard-bank rank 27) — a neighbor conventional features miss.
