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 (10/01/04) -- Three stream-gaging stations were discontinued as of October 1 , 2004, due to lack of operating funds. These stations can be reestablished if funding becomes available. The USGS stream-gaging network is maintained in collaboration with Federal, State, and local agencies. USGS provides matching funds in many cases, but in general cannot fund 100 percent of any gage by itself. Any Federal/State/local entity interested in contin uing the operation of any of the following gages should contact Gary Fisher at 410-238-4259 (e-mail gtfisher@usgs.gov).

A number of other stations in Delaware were planned for discontinuation on October 1, 2004, as part of short-term projects. The station on Stockley Branch was discontinued because local conditions have made the data less useful. Stations that were discontinued are:

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.
