Situational Awareness (Monday, 2026-10-12)
Yesterday’s average daily flow at the USGS Point of Rocks gage was 2,140 cubic feet per second (cfs), above the 2,000 cfs threshold for CO-OP daily drought monitoring. Flow has continued to rise, with today’s flow estimated at 2,980 cfs based on recently available real-time data. CO-OP is therefore suspending its daily drought monitoring and reporting.
Situational Awareness (Sunday, 2026-10-11)
According to the Middle Atlantic River Forecast Center, the Potomac basin received approximately 0.25–1.5 inches of rain over the past 24 hours, with locally higher amounts up to 2 inches in the southwestern portions of the basin. Widespread rainfall of 1–1.5 inches is forecast over the next three days, with localized totals reaching 2 inches.
Situational Awareness (Saturday, 2026-10-10)
No rainfall was observed over the past 24 hours in the Potomac basin upstream of Little Falls, Maryland. 1 to 3 inches of rain is expected over the next three days.
Special Conditions
Intra-daily flow fluctuations at Potomac River gages, including Point of Rocks, are occurring due to upstream dam operations associated with eel passage.
Situational Awareness (Friday, 2026-10-09)
During the last 24 hours, the Middle Atlantic River Forecast Center reported no significant observed rainfall in the Potomac River Basin. They predict 1.0 to 1.75 inches of rainfall during the next three days, with a similar seven-day forecast total.
Special Conditions
Intra-daily flow fluctuations at Potomac River gages, including Point of Rocks, are occurring due to upstream dam operations associated with eel passage.
Situational Awareness (Thursday, 2026-10-08)
No rainfall was observed over the past 24 hours in the Potomac basin upstream of Little Falls, Maryland. The Middle Atlantic River Forecast Center forecasts 0.1 to 0.5 inches of rain over the next three days. Widespread rainfall totaling 1 to 2 inches is forecast over the next week.
Special Conditions
Intra-daily flow fluctuations at Potomac River gages, including Point of Rocks, are occurring due to upstream dam operations associated with eel passage.
Situational Awareness (Wednesday, 2026-10-07)
According to the Middle Atlantic River Forecast Center predictions, the next 24 hours are not expected to see any rain. They further predict that over the next 3 days, no rain is expected. The week-long outlook, however, could total approximately 1.5 inches of rain in the basin.
Special Conditions
Intra-daily flow fluctuations at Potomac River gages, including Point of Rocks, are occurring due to upstream dam operations associated with eel passage.
Situational Awareness (Tuesday, 2026-10-06)
According to the Middle Atlantic River Forecast Center predictions, the next 24 hours may see 0.0 inches of rain. Over the next 3 days, the average basin rainfall may be around 0.0 inches. The week-long outlook expects a total of approximately 0.5 inches of rain in the basin.
Situational Awareness (Monday, 2026-10-05):
CO-OP is initiating daily drought monitoring and reporting today because Potomac River flow at the US Geological Survey’s gage at Point of Rocks, Maryland, has fallen below 2000 cubic feet per second (cfs), CO-OP's daily monitoring threshold.
Light, scattered rainfall of up to 0.1 inch was observed yesterday in the Potomac basin upstream of Little Falls, Maryland. No substantial rain is expected over the next week.
Situational Awareness (Thursday, 2026-09-24)
Yesterday’s average daily flow at the USGS Point of Rocks gage was 2570 cubic feet per second (cfs), above the 2000 cfs threshold for CO-OP daily drought monitoring. Flow has continued to rise, with today’s flow estimated at 3600 cfs based on recently available real-time data. CO-OP is therefore suspending its daily drought monitoring and reporting.
Situational Awareness (Wednesday, 2026-09-23)
Yesterday’s average daily flow at the USGS gage at Point of Rocks was 1,640 cfs, below the 2,000 cfs threshold for CO-OP daily drought monitoring. Flows are increasing, however, due to recent rainfall, with instantaneous flows at Point of Rocks reaching 2,450 cfs this morning. The decision to discontinue daily drought monitoring will be considered if the average daily flow rises above the 2,000 cfs threshold.
