All rivers with average discharge more than 15,000 cubic feet per second are listed. Estimates are approximate, because data are variable with time period measured and also because many rivers lack a gauging station near their point of outflow.
The USGS has maintained a gauge (01196620) near Sleeping Giant for the past 41 year to continuously monitor flow. Real time data are available here. A trail is under development that follows the course of the river, especially in the city of New Haven.
A stream hydrograph is commonly determining the influence of different hydrologic processes on discharge from the subject catchment. Because the timing, magnitude, and duration of groundwater return flow differs so greatly from that of direct runoff, separating and understanding the influence of these distinct processes is key to analyzing and simulating the likely hydrologic effects of ...
USGS operates a number of water-related programs, notably the National Streamflow Information Program [23] and National Water-Quality Assessment Program. [24] USGS Water data is publicly available from their National Water Information System [ 25 ] database.
Additionally, USGS uses hydrographs to study streamflow in rivers. A hydrograph is a chart showing, most often, river stage (height of the water above an arbitrary altitude) and streamflow (amount of water, usually in cubic feet per second). Other properties, such as rainfall and water quality parameters can also be plotted. [9]
Within the USGS, the Water Resources Division carries the responsibility for monitoring water resources. To establish a stream gauge, USGS personnel first choose a site on a stream where the geometry is relatively stable and there is a suitable location to make discrete direct measurements of streamflow using specialized equipment.
Historical documents from Danbury and surrounding towns cited the river as a sewage dump around the 1880s, and the water was unusable for both agricultural and industrial use. [4] It wasn't until a court case ruling] in 1895, along with the Clean Water Act in 1972 that the city of Danbury was required to take responsibility for the state of the ...
Baseflow (also called drought flow, groundwater recession flow, low flow, low-water flow, low-water discharge and sustained or fair-weather runoff) is the portion of the streamflow that is sustained between precipitation events, fed to streams by delayed pathways.
