Revised June 3, 2002

Flood Warning Improvements Funded or
Completed Since April 2001 in the
Delaware River Basin

  1. Full coverage of the basin by NOAA Weather Radio transmitters except for local terrain interference. (National Weather Service [NWS])

  2. Modernization of NWS Mount Holly Weather Radio system. (NWS)

  3. New stream gages at the following locations:
  4. Re-installed or modernized stream gages at the following locations:
  5. Funding for rating curve extension and maintenance:
  6. PPL Generation, Inc. now provides real time lake level data for Lake Wallenpaupack on its web
    site at: http://www1.pplweb.com/ilwpk/cgi-bin/present_operation.pl.

  7. Using New Jersey state funds provided for drought monitoring, and funds from other sources, the New Jersey District of USGS has reactivated the following stream gages and equipped the gages with satellite telemetry:

    Additionally, satellite telemetry has been or will be added at the following existing gages:

  8. Installation of satellite telemetry for the stream gage at the Brandywine Creek at Wilmington.

  9. Satellite telemetry has been installed for the gages at the Neversink River at Bridgeville and the Delaware River at Barryville.

  10. Emergency Telephone Notification for Lower Neshaminy Creek using Community Alert System. (Bucks County)

  11. Web posting of 5-day significant flood outlook and flood frequency analysis products by the NWS Mid-Atlantic River Forecast Center.

  12. Development by the NWS Mid-Atlantic River Forecast Center of Advanced Hydrologic Prediction Services (AHPS) test products for 30-day probabilistic inflow forecasts for F.E. Walter Reservoir, Blue Marsh Reservoir, Cannonsville Reservoir, and Pepacton Reservoir. Posted on web (NWS).

  13. Web posting of contoured precipitation forecast maps for the region by the NWS Mid-Atlantic River Forecast Center (up to 48 hours lead time).

  14. Doppler radar estimates of precipitation (one hour and storm total) for each of the radar stations in the Middle Atlantic Forecast Center region.

Items In Progress

  1. The National Weather Service and New York City Department of Environmental Protection are working to equip New York City's rain gages with telemetry so that readings are available to the NWS (view NWS press release for details).

  2. The University of Delaware (State Climate Office, Center for Climatic Research, and Delaware Geological Survey) has proposed the Delaware Environmental Observing System (DEOS). This would add 25 additional weather observation sites in the state and integrate weather observations with radar estimates of precipitation, and GIS to provide real time assessments of coastal and stream flood risk potential. The focus is on the availability of real time data for all types of weather conditions. There are only three hourly weather stations in Delaware at this time. This is a five-year program with an estimated one-time cost of $1.64 million and annual operation and maintenance costs of $0.21 million. Delaware is seeking appropriations for the work. Products from this work appear compatible with AHPS.
