Water year 2026
—
records in this curated snapshot. The official anonymous report listed 68 records on Sep 28, 2026; this map stores 20 factual records, so it is not exhaustive.
Interpretation
Official fields, cached snapshot. Marker location, river, date, jam type and condition come from the USACE CRREL Ice Jam Database. No MitchellCo forecast or risk score is calculated. “Current condition” means the condition recorded by CRREL for that event, not a guarantee of present river conditions.
Source & vintage
CRREL reports more than 18,000 U.S. records in the full Ice Jam Database. This static subset was captured from the anonymous Water Year 2026 report on Sep 28, 2026. It is intentionally build-time/static to avoid browser fan-out and does not claim live closure or forecast status.
