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).
