Situational Awareness (Tuesday, 2025-09-02):
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 2,000 cubic feet per second (cfs), CO-OP's daily monitoring threshold.
Situational Awareness (Tuesday, 2024-11-19)
Today, CO-OP is suspending its daily drought monitoring and reporting. This phase of CO-OP’s drought response is triggered when daily Potomac River flow at the USGS’s Point of Rocks gage falls below 2000 cubic feet per second (cfs). Yesterday’s flow rose above that threshold. According to the Middle Atlantic River Forecast Center predictions, the average basin rainfall may be up to 0.5 inches over the next 3 days. We will continue to monitor conditions closely and we will resume daily drought monitoring if needed.
Situational Awareness (Monday, 2024-11-18)
While the daily average flow at Point of Rocks has just crossed the 2000 cfs drought monitoring threshold (at 2020 cfs), ICPRB’s CO-OP Section will continue daily monitoring for the time being to ensure that the flow at Point of Rocks will remain above said threshold for an extended period of time. No appreciable rainfall is expected in the basin over the next 24 hours according to the Middle Atlantic River Forecast Center predictions. Over the next 3 days, the average basin rainfall may be around 0.25 inches.
