Concepts
  • SURFACE WATER:  Water which flows over, or rests on the surface of a land mass, natural watercourses such as rivers, streams, brooks, lakes, etc., as well as artificial watercourses such as irrigation, industrial and navigation canals, drainage systems, alluvium (subsurface water) and natural and artificial reservoirs. Excluded are sea-water, permanent bodies of stagnant water both natural and artificial, and transitional waters, such as brackish swamps, lagoons and estuaries.
  • REFERENCE PERIOD:  Period to which the information refers and which may be a specific day or a time interval (month, fiscal year, calendar year, among others).

Observations The indicator refers to the ecological status, which reflects the quality of the structure and functioning of the aquatic ecosystems associated to surface waters and it's evaluated through a comparison of the data obtained for the various quality elements (biological, hydromorphological, physicochemical and specific pollutants), with the reference conditions defined for each ecotype.
