| Station Type |
Description |
| ATMOSPHERE |
Established primarily to measure meteorological properties or atmospheric deposition. |
| CANAL |
An artificial, channeled waterway used for navigation, drainage, land irrigation, etc. Includes drainage ditches. |
| DITCH |
An excavation artificially dug in the ground, either lined or unlined, for conveying water for drainage or irrigation; it is smaller than a canal. |
| ESTUARY |
That part of a river or stream or other natural body of water having unimpaired connection with the open sea, where the sea water is measurably diluted with freshwater derived from land drainage. Includes lagoons, bays. |
| ESTUARY/AMBNT |
|
| FACILITY |
A man-made facility. Includes water supply, wastewater treatment and industrial sites, sewers. |
| LAKE |
An inland body of water, naturally formed. Includes ponds. |
| LAND |
A station located on a body of dry land and samples soil, air, precip, etc. |
| LAND RUNOFF |
|
| OCEAN |
The open sea. |
| POREWATER |
Water in the pores of a saturated soil layer |
| RESERVOIR |
A man-made body of water formed by damming or obstructing a stream or river (many lakes are actually reservoirs). |
| RIVER/STREAM |
A naturally occurring, freshwater, free-flowing channeled body of surfacewater, with regular or seasonal flow, that empties into an ocean, lake, reservoir or another stream. |
| SEEPAGE |
The sediment-water interface as typically monitored with a seepage meter. |
| SPRING |
A natural flow of groundwater from the earth, which feeds into a stream or body of water on the surface. |
| SPRING, GW |
Spring, Ground Water - As defined by the United States Geological Survey. A location at which the water table intersects the land surface, resulting in a natural flow of groundwater to the surface. Springs may be perennial, intermittent, or ephemeral.
|
| TIDAL STREAM |
A stream reach where the flow is influenced by the tide, but where the water chemistry is not normally influenced. A site where ocean water typically mixes with stream water should be coded as an estuary. |
| WATERSHED |
The area of land where all of the water that drains off of it goes into the same waterbody?a river, stream or lake. |
| WELL |
An artificial excavation from which groundwater is drawn or through which liquid waste is disposed of by injection. |
| WETLAND |
A lowland area, such as a marsh or swamp, that is saturated with moisture, especially when regarded as the natural habitat of wildlife |
