National hydrography dataset--linear referencing [More info]: Explains how the NHD specifies point locations within streams by using a code to indicate the reach (including the hydrologic unit) and a measure, which indicates how far the point is from the downstream end of the reach.
Nevada Water Science Center Projects [More info]: Links to detailed descriptions of USGS water-related research projects in Nevada with project information, location maps, and bibliographies including online reports.
New Jersey District - surface water information [More info]: Links to water data for New Jersey including streamflow, sampling stations, and water-quality data with links to reports on stream gages, hydrology, networks, and floods.
North Dakota River Basin map for current streamflow conditions [More info]: Links by geographic area in North Dakota or by gaging station number to hydrographs, downloadable data, and site description of streamflow stations.
Organic compounds in Elm Fork Trinity river water used for public supply near Carrollton, Texas, 2002-05 [More info]: We identified six compounds at concentrations less than human-health benchmarks, but within a factor of 10 of those limits. Those compounds might warrant further study to understand their transport and fate within the watershed.
Pesticides in Midwestern rivers, 1989-2002 [More info]: Overview of aspects of research on pesticides and herbicides in Midwestern rivers with collection of data, results over a period of time, online publications, and bibliography.
Possible effects of groundwater pumping on surface water in the Verde Valley, Arizona [More info]: We applied a groundwater model to simulate effects of groundwater pumping and artificial recharge on surface water in this area. Results show effects of pumping or recharge on streamflow.
Real-time water levels for reservoirs in Puerto Rico [More info]: Links to stations in Puerto Rico for real-time information on water levels for reservoirs.
Regional assessments of the Nation's water quality--Improved understanding of stream nutrient sources through enhanced modeling capabilities [More info]: Studies of the sources, transport, and fate of nutrients in the streams of six major regions of the conterminous United States.
Relations among geology, physiography, land use, and stream habitat conditions in the Buffalo and Current River systems, Missouri and Arkansas [More info]
