River conditions once we get in to the season will be updated daily. However there are a few places we go to predict fishing conditions based on flow. As what we do here is both river flow and tidal fishing both factors contribute to fishing conditions. The primary indicator we use os the river flow levels at the USGS Little Falls pump station.
Fishing the Tidal Potomac tends to be optimal when the flow is at or below 5 feet and the temperature around 15-19 Dergees Celcius.
