Click on a river basin to obtain real-time data. Quick Links to Real-Time Data 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.
Of Current InterestNew Publication: Relation of Watershed Setting and Stream Nutrient YieldsSandy Run Tributary to Middle Swamp watershed, Greene County, NC The U.S. Geological Survey conducted a cooperative study with the North Carolina Division of Water Quality to characterize relations between watershed settings and stream nutrient yields throughout central and eastern North Carolina. Stream yields of nitrate, total nitrogen (N), and total phosphorus (P) were compiled for 48 sites for the 1997 to 2008 study period. Compiled environmental data (including variables for land cover, hydrologic soil groups, streamflows, wastewater treatment facilities, and confined animal feeding operations) were used to characterize the watershed settings for the study sites. Data analyses indicated that grouping and examining stream nutrient yields based on land-use classifications developed for the study can be useful for characterizing relations between watershed settings and nutrient yields. The analysis of data with four regression tree models further indicated that some of the environmental variables examined in the study were useful for predicting stream yields of nitrate, total N, and total P. The regression tree models can serve as a tool for relating differences in select watershed attributes to differences in stream nutrient yields, which can provide beneficial information for improving nutrient management in streams throughout North Carolina and for reducing nutrient loads to coastal waters.
