  2. Stream gauge - Wikipedia

    en.wikipedia.org/wiki/Stream_gauge

    The first routine measurements of river flow in England began on the Thames and Lea in the 1880s, [2] and in Scotland on the River Garry in 1913. [3] The national gauging station network was established in its current form by the early 1970s and consists of approximately 1500 flow measurement stations supplemented by a variable number of temporary monitoring sites. [2]

  3. Freshwater environmental quality parameters - Wikipedia

    en.wikipedia.org/wiki/Freshwater_environmental...

    Because almost all water bodies are dynamic in their composition, the relevant quality parameters are typically expressed as a range of expected concentrations. They include the natural and man-made chemical , biological and microbiological characteristics of rivers , lakes and ground-waters , the ways they are measured and the ways that they ...

  4. Water quality - Wikipedia

    en.wikipedia.org/wiki/Water_quality

    The National Water Quality Inventory Report to Congress is a general report on water quality, providing overall information about the number of miles of streams and rivers and their aggregate condition. [65] The CWA requires states to adopt standards for each of the possible designated uses that they assign to their waters.

  5. Flood stage - Wikipedia

    en.wikipedia.org/wiki/Flood_stage

    Example graph of stream stages showing Action Stage, Flood Stage, Moderate Stage, Major Stage, and Record Stage on a river. Flood stage is the water level, as read by a stream gauge or tide gauge, for a body of water at a particular location, measured from the level at which a body of water threatens lives, property, commerce, or travel. [1]

  6. Stream restoration - Wikipedia

    en.wikipedia.org/wiki/Stream_restoration

    The pools raise the water level and allow fish to swim over a partially-submerged sewer pipe which crosses the creek. [27] These structures, which can be built with rocks or wood (logs or woody debris), gradually lower the elevation of the stream and dissipate flow energy, thereby reducing flow velocity. [7] They can help limit bed degradation.

  8. Pollution of the Hudson River - Wikipedia

    en.wikipedia.org/wiki/Pollution_of_the_Hudson_River

    The most recent comprehensive report on the health of the Hudson River, published in 2020, states that "Water quality in the Hudson River Estuary has improved dramatically since 1972 and has remained largely stable in recent years." Ecological health trends, such as in tributaries and wetlands, are varied in condition. [40] [41]

  9. Stage (hydrology) - Wikipedia

    en.wikipedia.org/wiki/Stage_(hydrology)

    In hydrology, stage is the water level in a river or stream with respect to a chosen reference height. [1] [2] It is commonly measured in units of feet.Stage is important because direct measurements of river discharge are very difficult while water surface elevation measurements are comparatively easy.
