USGS Current Water Data for Delaware

Click to hide state-specific text
Data collected by the MD-DE-DC USGS Water Science Center are reported in Eastern Standard Time (EST) year-round.

Updated April 1, 2016: USGS streamflow monitoring will soon be discontinued at the following sites:
  • 01490200 FARM CREEK NEAR TODDVILLE, MD (2015 to present) Data collection has been discontinued
  • 01487150 BUCKS BRANCH NEAR ATLANTA, DE (2014 to present) Data collection discontinues July 1, 2016
Currently, data collection activities at these sites (map) are funded jointly by the USGS and partner agencies through the USGS Cooperative Water Program. Lack of partner funding for these sites will result in discontinuation of all monitoring activities. Questions or concerns can be directed to Jon Dillow (jjdillow@usgs.gov; 443-498-5524).

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.
