Anyi Wang shared HUC4 Drought-Rainfall Correlation: Processed Water Use and Reservoir Data (2000–2020)
Type: Resource
Date: July 9, 2026, 5:22 p.m.

ABSTRACT:

Processed datasets supporting the comparative analysis of drought indices (SPI, SPEI, PDSI)
and precipitation correlation across ~222 CONUS HUC4 watersheds (2000–2020).
Includes monthly irrigation and public supply water withdrawal data aggregated to HUC12,
and per-reservoir storage time series. Generated as part of the 2026 REU project at
the University of Illinois Urbana-Champaign.
