Daily Streamflow Conditions

Select a site to retrieve data and station information.
Stream gage levels in Virginia, relative to 30 year average.

Explanation
	High
	> 90th percentile
	76th - 90th percentile
	25th - 75th percentile
	10th - 24th percentile
	< 10th percentile
	Low
	Not ranked

The colored dots on this map depict streamflow conditions as a percentile, which is computed from the period of record for the current day of the year. Only stations with at least 30 years of record are used.

The gray circles indicate other stations that were not ranked in percentiles either because they have fewer than 30 years of record or because they report parameters other than streamflow. Some stations, for example, measure stage only.

Real-time data typically are recorded at 15-60 minute intervals, stored onsite, and then transmitted to USGS offices every 1 to 4 hours, depending on the data relay technique used. Recording and transmission times may be more frequent during critical events. Data from real-time sites are relayed to USGS offices via satellite, telephone, and/or radio and are available for viewing within minutes of arrival. All real-time data are provisional and subject to revision.
