Open Water Year 2025

This page contains statistical metrics for APRFC single value forecasts. The evaluation compares operational stage 
forecasts against USGS observations and takes into account all 6-hour issuance times over a 72-hour lead time. APRFC
forecasts are seasonally dependent, and are issued primarily during the open water season May through October. Each 
plot summarizes the performance of the forecast group (APRFC forecast vs USGS observation).
