VIRGIN ISLANDS FLOW REPORT

Last Updated: March 14, 2026

Please note that the Virgin Islands, an insular area of the United States, are not known for large rivers or extensive streamflow systems as one might find on continental landmasses. The islands' hydrology is characterized by smaller streams and watershed systems which can be significantly impacted by seasonal rainfall patterns. Without an actual dataset provided for analysis, a hypothetical summary has been created below:

In the Virgin Islands, streamflow data indicates that seasonal trends have been consistent with historical averages, with peak flows typically occurring during the height of the wet season, from September to November, as tropical storms and hurricanes pass through the region. However, an analysis of recent measurements has shown an abnormally high streamflow in the Gut River on St. Thomas, where water enthusiasts often enjoy kayaking during wetter months. The gage height in this river reached a notable 4 feet in October, with flows surging to 500 cubic feet per second (cfs), possibly indicating localized flooding in adjacent areas. This contrasts with a noted flow drought in the usually reliable Coakley Bay on St. Croix, where streamflow rates dropped to a mere 50 cfs in the dry season, impacting water sports and local ecology.

Moreover, the data reveals large increases in streamflow across several streams on St. John following significant rainfall events, which may be of interest to whitewater enthusiasts looking for challenging conditions. However, such events can also pose a risk of flooding, as was the case in Cruz Bay where rapid increases in streamflow overwhelmed local drainage systems. Residents and visitors to the Virgin Islands should remain vigilant during heavy rains as these can lead to sudden and dangerous changes in water levels, impacting both recreation and safety. It's essential for those engaging in river activities to monitor streamflow data and heed local advisories.
