Stream gage levels in Dist. of Columbia, relative to 30 year average.

Explanation
	High
	> 90th percentile
	75th - 89th percentile
	25th - 74th 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.

NOTICE (03/31/2008) --Data collection at the following gages will be discontinued due to funding reductions from partner agencies. Although historic data will remain accessible, no new data will be collected unless one or more new funding partners are found. Users who can contribute funding for the non-Federal share of costs to continue operation of these streamgages should contact Jim Gerhart of the USGS Maryland-Delaware-DC Water Science Center at (443-498-5501, jgerhart@usgs.gov).

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.
