Periodically updated streamflow statistics are essential for the effective management of water resources in New Jersey.StreamStats provides access to spatial analytical tools that are useful for water-resources planning and management, and for engineering and design purposes. A streamgage is a structure installed beside a stream or river that contains equipment that measures and records the water level (called gage height or stage) of the stream.
The Upper Yampa River Basin (UYRB) drains approximately 1,800 square miles west of the Continental Divide in northwestern Colorado. We are using USGS streamgage data and MPCA IBI data to develop relations...Many Dane County, Wis., streams and lakes have been degraded due to excessive nutrients and sediment contributed primarily by agriculture and urbanization. The user sends an email or text message containing a USGS current-conditions gaging site number, and will quickly receive a reply with the station's most recent data for one or more of its monitored parameters.The U.S. Geological Survey WaterAlert service sends e-mail or text (SMS) messages when certain parameters, as measured by a USGS real-time data-collection station, exceed user-definable thresholds. Water-quality “super” gages (also known as “sentry” gages) provide real-time, continuous measurements of the physical and chemical characteristics of stream water at or near selected U.S. Geological Survey (USGS) streamgages in Ohio, Kentucky, and Indiana.
Flood. Rather, streamflow monitoring involves several steps, which generally include (1) continuously measuring and recording the stage of a stream, (2) periodically taking discharge measurements in the stream, (3) developing the relation between stage and discharge for the site and applying this relation to the continuous stage record to compute streamflow (discharge).A streamgage usually measures stage every 15 minutes. Rating curves are developed from numerous physical stream discharge measurements collected over a period of time and over a range of stages (from low flow to flood stage).
How can one tell how much water is flowing in a river? This is generally done by multiplying the cross-sectional area of water in the stream channel by the average velocity of the water in that cross section (see below).

In Michigan, USGS operates 24 traditional crest-stage gages, where stage and streamflow is only measured during high flows, and 6 continuous-record crest-stage gages, where cooperators can continually monitor stage and USGS maintains a high-...Humans, just like aquatic organisms, need water. These basins have been used in several USGS studies such as James Falcone's "GAGES-II: Geospatial Attributes of Gages for Evaluating Streamflow" (2011) and Xiaodong Jian and others, "WaterWatch-Maps, Graphs, and Tables of Current, Recent, and Past Streamflow Conditions " (2008). Flood control, urban infrastructure, irrigation of agriculture, and myriad other ways we manage water affect the natural flow of streams and rivers. The rating curve for almost every streamgage will vary over time due to changes in the stream channel resulting from sedimentation, scour, ice, debris, growth of aquatic vegetation, etc.
When extensive records of past streamflows exist, it is possible to see a pattern of streamflow variation by month and season.
