  • January 22, 2018 - USGS Water Data availability during lapse in Federal funding

    Due to a lapse in Federal funding, the U.S. Geological Survey must suspend those parts of its data collection and distribution processes requiring human intervention. However, automated reporting and serving of telemetered data will continue.

    Users may note some degradation in the quality and completeness of real-time streamflow, groundwater and water-quality data from some reporting stations due to the suspension of field calibrations and adjustments, especially as high flows occur, aquatic vegetation becomes dominant, or ice forms in high altitude streams. The USGS will continue to monitor some performance aspects of its network using a skeleton workforce.

   Prior to October 1, 2015, at datum 1.05 ft higher.
REMARKS.--This is a tidal station. Discharges are not determined at this location. U.S. Geological 
   Survey satellite data-collection platform at station. 
EXTREMES FOR PERIOD OF RECORD.--Maximum elevation, 8.41 ft, datum then in use, October 30, 2012; 
   minimum elevation, -5.55 ft, datum then in use, March 6, 2007.
COOPERATION.--Funding for the operation of this station is provided by the Delaware Geological Survey.
Boating safety tips
7/28/2016 Notice to users - Water level data, beginning on 10/1/2015, at this site has been
re-computed to reference the water level to NAVD88 datum. In order to convert historic
water level data, stored in NGVD29 datum to the current NAVD88 datum, users must apply
known -1.05 ft. datum shift, as calculated for this location using VERTCON.
This station managed by the MD-DE-DC Water Science Center Dover office.
