There is an increasing pursuit of utilizing plants as a gear to predict, describe and
diagnose environmental stresses. Being united swiftly with their environments,
granting them to offer beneficial information on the condition of the aquatic
environment. The aquatic plant species are effectively reliable indices as water status
indicators. Their ability in taking up metal and toxic pollutants has shown their level of
strength as well as tolerance in any concentration levels. Eutrophication is also being
associated with the existence of aquatic plants. This widespread crisis in water bodies
is made by over enrichment with N and P. Excess nutrients can trigger undesirable
eutrophication, resulting in unhealthy algal blooms, spreading of certain aquatic
macrophytes, depletion of oxygen and loss of key species, resulting in widespread
degradation of many freshwater ecosystems. A broad number of physico-chemical
parameters and biological characteristics render the degree of quality of water
resources. Supervising above parameters is a crucial part to classify the magnitude
and origin of any pollution load. The study was carried out to determine the levels of
Nitrite (NO2), Nitrate (NO3) and Phosphate (PO4), in different stations of urban lakes
in Kuala Lumpur and Selangor. Data for physico-chemical parameter were classified
according to the Interim National Water Quality Standard, Malaysia (INWQS). The
significant outcome of this research is the abundance or loss of certain key species can
be used as indicator for eutrophication state and level for urban lakes management
and maintenance
