Phytoplankton samples were collected as per standard
methods (APHA , 2005) from predetermined sampling stations [S.Ibypass
bridge (upstream of river Bhadra before the entry of industrial
effluents and domestic sewage from Bhadravathi town), S.II- railway
bridge (after the release of MPM effluent to the river Bhadra, 0.5 km
away from the point source of pollution), S.III- new bridge (after the
addition of VISL industrial effluent and domestic sewage from the
Bhadravathi town), S.IV- Nagathi belagalu (Nearly 10 kms away
from the Bhadravathi town), S.V- Holehonnur (before river Bhadra
joins river Tunga in Kudli] from the point of upstream stretch to
effluent outfall along with the downstream stretch, arbitrarily designed
in five sectors in three different seasons, premonsoon, postmonsoon
and monsoon for two years (2004-2005). The collected samples
