Flood — Archuleta, Colorado

2025-10-13 to 2025-10-15 · near Pagosa Spgs, Archuleta, Colorado

Event narrative

The San Juan River reached a second crest to major flood stage that was even higher than the first in response to additional significant rainfall and locally heavier rates on October 13. This heavy rainfall was due to the remnants of Tropical Storm Raymond on top of already saturated ground from the previous surge from Tropical Storm Priscilla. The San Juan River climbed back to action stage on October 13 at 1300 MST at 9.48 feet. The second crest reached major flood stage on October 14 at 300 MST at 12.88 feet. The San Juan River then fell below action stage on October 15 at 700 MST.

Wider weather episode

Between October 10-14, 2025, southwest Colorado experienced prolonged periods of rain and some of the largest multiday rainfall totals on record with rainfall accumulations between 3 and 8 inches, with locally higher amounts across the San Juan Mountains. Remnants from two tropical storms supplied anomalous moisture across the region, with minimal break between events. The first round of heavy rainfall resulted in flooding across La Plata and Archuleta counties from decaying Tropical Storm Priscilla beginning October 10 and continuing throughout the day on the 11th. There was a break in rain across the area on October 12, followed by a second round of heavy rain from October 13-14, associated with moisture from remnant Tropical Storm Raymond. Without much time between systems, the hydrologic response of the second storm was much faster than the first. Flooding across several counties in southwest Colorado spiked twice within the 5-day window, leading to major flooding and near record peaks along the Vallecito, Piedra and San Juan watersheds that lingered through the 16th before water levels receded. Numerous debris flows and rockslides also occurred as a result of the abundant rainfall.
