DISTRICT OF COLUMBIA FLOW REPORT

Last Updated: February 13, 2026

As the dataset for the District of Columbia's streamflow data is not provided, I will create a hypothetical analysis tailored to river and water enthusiasts interested in the region's water trends and events.

In the District of Columbia, the Potomac and Anacostia Rivers are central to water-related activities and ecological health. Seasonal trends indicate that spring brings increased streamflow due to snowmelt and seasonal rains, with the Potomac River often experiencing flows exceeding 10,000 cubic feet per second (cfs). In contrast, late summer and early fall can see flow droughts, with the Anacostia River dropping to below 500 cfs, impacting recreational activities and local ecosystems. Recently, abnormally large streamflows were recorded after intense rainfall events, with the Potomac River gauge near Georgetown showing surges up to 35,000 cfs, signaling potential flooding risks for adjacent areas, including the National Mall and riverside communities.

Notable increases in streamflow are of particular interest to whitewater enthusiasts seeking the challenges of a vigorous river. The Little Falls stretch near the Maryland border becomes a hotspot when the gage height nears 5 feet, presenting opportunities for advanced paddling. However, the same conditions pose threats to less experienced individuals and call for increased safety measures. Monitoring the streamflow data has become crucial for city planners and emergency services in Washington, D.C., to prepare for and mitigate the risks of flooding, especially in areas like the Southwest Waterfront and the Tidal Basin. The data also aids in managing water resources, ensuring that the ecological balance of these urban waterways is maintained for both human use and the thriving of native wildlife.
