Streamflow Tools

Centralized data management platform integrating USGS NWIS, NOAA River Forecast Centers, and Canadian Hydrometric Services. Manages 309 active monitoring stations with automated ingestion, PostGIS spatial queries, satellite raster data (RTMA & SMAP), and a full OpenAPI-documented REST API.

Real-time interactive dashboard for 1,500+ USGS monitoring stations across the Pacific Northwest. Features color-coded station maps, watershed boundary overlays (HUC2–HUC8), 7-day discharge graphs, water-year analysis, multi-year comparisons, and a full administrative interface for station management.

Interactive multi-date runoff comparison tool for the Columbia River Basin. Scrapes live NWRFC data on demand and renders slider-enabled Plotly maps—up to 10 can be open simultaneously for side-by-side percent-of-normal runoff analysis across any combination of dates.

ML post-processing system that corrects NWRFC 6-day deterministic streamflow forecasts by learning systematic residual errors. Trains XGBoost, LSTM, and MuTHRE probabilistic models across Columbia River Basin stations, with an interactive evaluation app for comparing model performance by lead day and residual type.

Estimates missing or erroneous readings at non-reporting SNOTEL (Snow Pack Telemetry) stations using regression analysis against neighboring stations. Useful for gap-filling snow water equivalent records and validating sensor anomalies across the Western U.S. mountain network.
