DISTRICT OF COLUMBIA FLOW REPORT
Last Updated: December 24, 2025
Please note that without an actual dataset provided, I am unable to reference specific measurements or give accurate data-driven insights. However, I can write a hypothetical report that would serve as an example of how you could interpret such data for the District of Columbia.
The District of Columbia, with its notable Potomac and Anacostia Rivers, has experienced a variety of streamflow conditions over the past season. During the spring, streamflows in the Potomac were above average, likely due to increased rainfall and snowmelt, appealing to whitewater enthusiasts looking for more challenging conditions. The Anacostia River, however, showed lower-than-expected flows, indicating potential flow drought conditions that may impact local ecosystems. Recreational users of the rivers in the district should note that the higher flows in the Potomac can offer exciting opportunities for water sports, but also require increased caution due to the stronger currents and potential for debris.
On the other hand, the summer months recorded an abnormally large streamflow event in the Potomac River, with gauge readings at Little Falls surging past 10,000 cubic feet per second (cfs), signaling potential flooding risks for adjacent areas such as Georgetown. Such conditions necessitated close monitoring by local authorities for flood control and safety measures. Conversely, the latter part of the season showed a significant decrease in flow rates, dipping below 5,000 cfs, which is considered low for this time of year and may affect water-based recreation and wildlife habitats. Overall, the fluctuations in streamflow highlight the importance of continuous monitoring for residents and visitors alike, ensuring both the enjoyment and safety of the district's river resources.
The District of Columbia experiences a humid subtropical climate, with hot summers and mild winters. The Potomac River is the major surface flow that runs through the city, and its tributaries include the Anacostia River and Rock Creek. The city's water supply comes from the Potomac River and its reservoirs, including the Great Falls Reservoir and Little Seneca Lake. Snowfall is a common occurrence in the winter months, and the city's snowpack plays a role in the seasonal flow of the Potomac and its tributaries. The District of Columbia is also susceptible to flooding due to intense rainfall events and storm surges from hurricanes.
