DELAWARE FLOW REPORT
Last Updated: January 23, 2026
The latest streamflow data for Brandywine Creek at Wilmington, Delaware, indicates a current streamflow of 170 cubic feet per second (cfs), which is notably below what is considered normal for this waterway, showing a 67.66% decrease from the average flow. This significant drop in streamflow, combined with a decrease of 8.11 cfs in the last 24 hours, suggests that river enthusiasts and residents in the area may experience lower water levels than usual. The current gage height is recorded at 8.5 feet, which can impact recreational activities and the aquatic ecosystem. Wilmington, a major city along Brandywine Creek, could see effects on water-dependent activities and local water management strategies.
Seasonal trends are important for understanding the health and behavior of Delaware's rivers. The deviation from normal streamflows, particularly in Brandywine Creek, one of the significant watercourses flowing through the Wilmington area, can signal potential flow droughts. This is a concern for those who enjoy paddling and fishing, as well as for the flora and fauna dependent on the river. Conversely, a large increase in streamflow could indicate potential flooding events, which calls for vigilance among communities living near the waterway. While the current data does not show such an increase, the change in streamflow is something that should be monitored closely, as abrupt shifts can quickly impact the river's condition and pose risks to those engaging with it for recreation or relying on it for water supply.
Delaware has a humid subtropical climate with moderate rainfall throughout the year. Major surface flows in Delaware include the Delaware River, the Brandywine Creek, and the Christina River. The Chesapeake Bay also borders the state. Major reservoirs include the Kent County Water Supply and the Betts Pond. The state is susceptible to coastal flooding and inland flooding due to heavy rainfall. Watershed data indicates that most of the state is within the Delaware River Basin, although small portions are within the Chesapeake Bay and the Atlantic Ocean Basins. Snowpack is typically low in Delaware due to the warm winter temperatures. Overall, the hydrology of Delaware is influenced by its coastal location, moderate rainfall, and dominant surface flows.
Winter Storm Warnings
January 23 2026
Residents of Delaware are urged to prepare for hazardous weather conditions as a Winter Storm Watch is in effect from January 23 through January 26. Anticipate heavy mixed precipitation with potential snow accumulations of 8 to 15 inches and ice accumulations up to a quarter of an inch. Central, northern, and southern regions of the state may face power outages and tree damage, with travel becoming nearly impossible, seriously impacting Monday morning's commute. Additionally, a Cold Weather Advisory warns of extremely cold wind chills as low as 7 below zero, posing risks of frostbite and hypothermia. It's crucial for communities across Delaware to take precautions and stay informed as these severe conditions approach.
